Today’s modern diets can often mean we eat too much or too little fat, or frequently just the wrong type. Our cell membranes consist of lots of oil aka. fat. For optimal performance they require quite a specific ratio of different types of fats, especially with regard to the essential fatty acids (EFA’s), omega 3 and 6. If these are out of sync, cells can malfunction a bit like trying to run your car on the wrong type of oil or petrol.
Cell membranes are your cells’ border control. They control what gets in and what gets out. They act as both the gatekeeper and the hostess.
Every cell in your body has a cell membrane and your body has a lot of cells. Experts think we have in the region of 30 trillion, and we want every one of these to have a healthy cell membrane. If your cell membranes are working correctly, they will let micronutrients in and waste products out. As well as supervising which molecules can enter and exit, most cell metabolism takes place in, on, or around this location. It’s like your very own production line inside you, manufacturing energy and proteins, and churning out waste products such as urea and toxins.
The next thing to understand is that their structure is critical to how well they function. We don’t want them to be too rigid or nothing will get in, or out. We also don’t want them too soft and floppy. This might allow too much in or too much out and over time this could cause multiple issues.
So how can we nourish them and maintain their structure so they can function properly? Firstly, the fat they contain needs to be eaten, as the body cannot make it. Some of these fats have special functions such as the EFA’s. There are many arguments about the correct ratio of fats to eat in the diet but researchers generally agree that we tend to be more deficient in omega 3 which is found in fish, nuts, seeds and vegetable oils.
So by now I think you get the idea that I like my clients to achieve healthy cell membranes because “the stronger our cells the more resilient our selves”.
It’s easy to check our ratios with a simple finger prick test because the concentration in our blood has been found to strongly reflect our dietary intake. The current European average for our omega 3 percentage is less than 4% but research confirms that 8% is optimum, and that this ratio is associated with a 90% reduction in risk of sudden cardiac death.
There is nothing like analytics to demonstrate to my clients (and me) that we either need to work harder on our diet or take targeted supplements to give our cells what they need to function tip top.
Here's Derek from Luxor Wellbeing explaining a bit about what he does. Hope it peaks your curiosity.
Using a combination of traditional therapies like Deep Tissue Massage, modern TECAR electrotherapy and, most importantly, working with your body’s energy flows using Radiesthesia, we work holistically, linking your body, mind and spirit together. The combination approach works just as well if you’ve suffered a physical or psychological trauma, we can aid your recovery, support your rehabilitation, and help you achieve enrichment.
This is wellbeing for the mind, body and spirit.
No one therapy generally is the answer.
Humans are a fantastic mix of physical, chemical, mental, spiritual, mechanical and electrical systems, and as such we need a holistic approach to our wellbeing to achieve our best.
That’s why at Luxor we look at you holistically, and the therapies we offer compliment and support each other. Deep tissue massage is a great tool, but it’s far more powerful when combined with a balancing of your energy fields with Radiesthesia. The use of our hi technology TECAR electrical therapy works very well on physical aspects of the body, but ensuring you have the right state of mind is just as important when recovering from trauma or injury.
A significant contributor to our wellbeing, both physical and psychological is our emotional balance. Our subconscious has its own beliefs, and these can quite often be at the root of a lot of our physical pain. Using Radiesthesia we can access the subconscious, bypass the intellect, and realign the inner mind.
Our brains have a map of every cell in our body, it knows what every bit of us should be doing and when this map gets damaged or interfered with then we suffer physical and phycological dysfunction. Being able to help our brain recover that map is a powerful element of our approach and it lays at the centre of our key therapy – Radiesthesia.
But its not all doom and gloom, Massage, TECAR and Radiesthesia can be used together to enrich you, build a better you, increase your energy, reinforce your overall balance of Body, Mind and Spirit.
A simple example of the approach……………a client has some pain in a particular joint, they’ve seen a doctor and there’s nothing obvious to diagnose, we test to see if it has an emotional element, if it does then that’s where we start, if not we would use the TECAR machine to warm up the joint, its muscle and tendons, its ligaments and its bone. This promotes vasodilation and brings more blood flow and nutrients to the joint, it also improves lymph flow and the removal of toxins. The energy input fires up fibroblast cells which secrete collagen the building block of all new cells……….. Using massage and stretch techniques we would ensure the joint is capable of its full range of movement and the associated muscles are providing the right control. Using Radiesthesia we would ensure the area has optimal energy fields around it, ensuring the brain has retaken full control of the joint and the nerves associated with the joint.

This month I did a fascinating webinar with Dr Jenny Goodman, author of Staying Alive in Toxic Times, and more recently Getting Healthy in Toxic Times. Jenny is an ecological Doctor, very well respected author and rigorous researcher. The webinar was about her top 7 strategies, based on her up to date findings and research. The book will cover many more issues of course.
We all know now that everything is connected and we need to become kinder and more loving to everything, and everyone, especially nature. But how do we tackle this on an individual and daily basis? Her top three were nutrition, water filtration and cleaning up the home from indoor pollution. The issues covered in the book can cause overwhelm but as a practising Doctor she is an advocate of what I call ‘meeting people where they are’. So she includes advice regarding prioritisation and practical suggestions and ideas to tackle each area.
For example the first area ‘nutrition’ is a subject close to my heart but not everyone can afford top quality organic produce. My advice is always to buy the best you can afford. If you eat meat this is critical as animals concentrate toxicity through a process called bio-transformation. The body stores these toxins in fats to try to shield the body from harm.
There are useful strategies though such as avoiding those vegetables grown with the most pesticides such as grapes, strawberries and lettuce. You can sign up for a list of the ‘dirty dozen’ here https://mailchi.mp/pan-uk/dirty-dozen-23. There is of course also a prioritisation issue. According to Tim Spector we are one of the sickest countries in Europe but little attention is being paid to this. 33% of our income used to be spent on food, today just 8% so this is no doubt part of the problem.
Water filtration seems to be a rapidly developing area. I do have a hand-out on this if anyone is interested I am happy to send it out. She doesn’t give specific recommendations anymore because the companies themselves change what their products filter so the advice dates very quickly. What she outlines in her book are the questions which need to be checked before making a buying decision. The challenge of course is to filter out the harmful toxicity but retain or replenish the mineral content that can be lost in the process.
I was fascinated to learn that the Netherlands use physical filters and ultraviolet light to kill bacteria rather than chlorine as per the UK. This means they don’t drink ‘disinfection by- products’.
Where the home is concerned Jenny highlighted chemicals from cookware and soft furnishings, which are relatively easy to address. The most at risk are pregnant women and young children but pre conception couples should also take note here. Again there are options so if you can’t afford the organic mattress, you buy them in the summer and leave them to ‘detox’ with the windows open. Don’t paint the nursery very close to the birth etc.
I should add that there is also a lot of encouraging work being done by enterprising individuals, organisation’s and companies all of which is covered in the book. Her website if of interest is www.drjennygoodman.com.

The role of cholesterol and fats in cardiovascular disease (CVD)
Cholesterol and fat receive a lot of attention in the health and wellness media especially in connection with cardiovascular disease (CVD). Most of it is negative and places the blame for heart disease on high fats diets in general and more specifically the cholesterol molecule. Of course there are numerous CVD risk factors such as age, genetics, sedentary lifestyles, obesity, diabetes and so on but this blog is focused on clarifying the role of cholesterol and fats.
Where does cholesterol come from and what does it do?
Only about 20% of our cholesterol comes from diet, the remaining 80% is made by the liver. So why does our body make it, if it’s harmful?
Cholesterol is an essential component of many processes in the body including the formation of every cell membrane. Our cell membranes consist of 1/3 saturated fat, 1/3 polyunsaturated fat and 1/3 cholesterol and it is here that all cellular activity (metabolism) takes place.
Cholesterol is the raw material of hormone production and we manufacture vitamin D from it, via the action of sunlight. We also need it for bile, which facilitates fat absorption and toxin excretion. It’s a key component of the myelin sheath surrounding our nerve fibres making it important for brain and nerve function. The list goes on, but you can see how important it is for many critical functions.
How does cholesterol go wrong?
The problem occurs when there is damage to the delicate lining of our blood vessels. The immune system steps in creating plaques to try and repair the situation and over time they can narrow our arteries. This process can result in an oxidised cholesterol molecule (LDL-c), which depending on the size, density and number of them can increase cardiac risk.
If our cholesterol metabolism is working correctly however LDL-c should be picked up by HDL-c and returned to the liver for excretion. For this process to work properly it requires a consistent supply of antioxidants.
So as is often the case it’s a question of balance.
What causes blood vessel damage?
The biggest culprits are high blood pressure from stress, sugar, trans fats and inflammation. This is because:
High blood pressure caused by the stress hormone adrenaline causes turbulent blood flow, which can easily damage the delicate blood vessel lining. Adrenaline can be triggered by any stressor such as: erratic blood sugar, lack of sleep, financial or emotional difficulties.
Refined carbohydrates and refined sugar are pro-inflammatory and can form ‘advance glycation end products’ (AGE) which stick to plaques further narrowing the arteries.
Trans fats which are contained in most biscuits, cakes and ultra processed food, raise LDL-c as well as making these particles more dangerous (atherogenic).
Inflammation arises from various sources such as infection and toxicity but vascular cell damage is also inflammatory so a vicious cycle emerges.
What if cholesterol is high? WHAT IF TOTAL CHOLEST
This may or may not be a problem but it’s always wise to investigate. Ideally our total cholesterol:HDL-c ratio should be less than 4.5 for men and less than 4 for women. The other important ratio is the HDL:LDL - c ratio and this is kept in balance by our level of antioxidants.
Preliminary check
An easy way to assess if there might be an issue is to calculate your waist to hip ratio (WHR). This is a good indicator of the presence of fat around the organs (visceral fat). Women should be 0.8 or more with a waist measurement below 90 cm (35 inches). The ratio for men is 1.0 or more with a 102 cm (40 inch) waist or less.
Can nutrition and lifestyle help?
The good news is there is so much you can do with nutrition, lifestyle and supplements to balance cholesterol metabolism and reduce risk. Medication may be necessary especially if there are genetics at play but this can often be minimised if every thing else is addressed.
Nutritional therapy is always very unique and personalised but it tends to focus on the following:
Nutrition
Lowering inflammation levels - through dietary change and supplements if required. Levels of omega 3 in the diet are important to evaluate.
Making sure sources of fat in the diet are good quality and that fats used in cooking are very stable. Trans-fats should be eliminated as much as possible. Digestion and absorption of fats is assessed and improved if needed.
Is the diet high in processed carbohydrates and refined sugar? Any excess will be converted to fat. Fat in the body doesn’t only come from the fat we eat.
Ensuring sufficient Vitamin D levels – these are highly protective against heart disease.
Balancing the antioxidant status in the body and levels of B3 – testing can be useful here
Adjusting levels of fibre in the diet to facilitate cholesterol excretion.
Checking sulphur intake in the diet. We are often low due to soil deficiency or we may not convert it to sulphate so cholesterol circulates as LDL-c. Some diets such as FODMAP can be low in this nutrient.
Testing and supplementation
A preliminary urine and blood spot test can be done to gage risk, before making the decision to invest in a more expensive, comprehensive CVD profile. The latter does help to establish blood lipid (fat) levels and direct priorities. The number and size of LDL-c particles and whether or not they are oxidised also helps to pinpoint risk.
Appropriate supplementation to fill any dietary gaps and tackle priorities.
Lifestyle
Stress management - 75% of people admitted with heart attacks have normal cholesterol with LDL levels below average (Dr. Aseem Malhotra FRCP).
Improve sleep for physical and mental recovery.
Improving breathing function to maximise nitric oxide production. This relaxes the blood vessels, improving blood flow to deliver nutrients and oxygen to the tissues, including the heart and the lungs.
Exercise – the right sort appropriate for age.

Ultra processed food trial – ‘The results are in’
The results are in. This (2019) study involved 20 adults following either an ultra-processed (UPF) or unprocessed diet for 2 weeks at the NIH Clinical Centre. This was followed immediately by 2 weeks of the alternate diet. The diets were matched for nutritional composition: calories; energy density; macronutrients; sugar; sodium and fibre and participants were free to eat as much as they liked.
Despite composition matching, subjects on the UPF diet consumed an average of 508 extra calories per day, comprising more carbohydrate and fat, but not protein. Participants gained more weight during the UPF diet, an average of 1kg, and lost weight during the unprocessed diet. This implies that there is something about the processing itself which causes a metabolic issue.
Other interesting points to note were:
During the UPF diet
• The eating rate was faster
• Sodium consumption increased
• To compensate for the lower fibre level and match fibre intake for both diets, beverages with dissolved fibre were given
• Body fat mass increased
During the un-processed food diet:
• Appetite suppressing hormone increased
• Hunger hormone decreased
• Total cholesterol decreased
• Inflammation markers decreased
• Fasting glucose and insulin levels decreased
One thing is clear. Whilst there is much conflict about which diet is the ‘best’ the whole world seems to agree that avoiding processed foods is a good thing.

A lot of my clients rely on white rice or pasta for quick meals. I thought I would write this blog about the benefits of brown rice and how to prepare it. Hoping to convince you all that brown rice is the way forward.
Brown rice is a whole grain and a major source of complex carbohydrate, fibre, minerals and B vitamins. Once the husk is removed the rice is sold as whole or brown rice. Otherwise it is milled and polished at least three more times to remove the bran and the germ from the endosperm, producing white rice.
1. Slower energy release
White rice is quickly digested to sugar increasing the potential for blood sugar spikes which are associated with increased risk of type 2 diabetes and insulin resistance. The carbohydrate in brown rice is wrapped in fibre which our bodies can’t digest. This means brown rice is digested to sugar much more slowly with a much slower release of energy.
2. Fitter and fuller with fibre
Whole grains and fibre keep us full for longer which can help with weight management and keep our gut bacteria happy. This is turn supports our immune system, mental health and risk of multiple chronic diseases.
3. Good for the heart
The British Heart Foundation says: “Higher intakes of fibre are also associated with a lower risk of heart and circulatory disease, and some cancers.” Brown rice may therefore improve heart health due to its fibre content as well as another specific compound found in its outer layers.
4. Packed with nutrients
Most of the nutrients in a whole grain of rice can be found in its outer layers which are removed during the production of white rice. So brown rice is more nutritious being a better source of vitamins and minerals, including calcium, iron, phosphorous, magnesium, selenium, vitamin B1 (thiamine) and vitamin B6 (pyridoxine). Brown rice has 10 times the amount of B1 compared to white rice unless it is fortified. Vitamin B1 deficiency (beriberi) has been known to affect populations with a heavy reliance on white rice. This affects the heart, nerves and the muscles.
The protein content and the quality of whole grains is also much greater than that of refined grains.
5. Antioxidant supply
In January 2023, researchers identified the main antioxidant of brown rice as cycloartenyl ferulate (CAF). This not only protects cells it also boosts the production of antioxidants within other cells.
CAF is hybrid compound of two different types of antioxidant (polyphenols and phytosterols) which may help lower cholesterol levels, suppress inflammation and reduce chronic disease risk.
6. Soaking
This not only reduces cooking time but lowers the arsenic content which can be high in rice according to the FDA. The soaking also makes the nutrients in rice more absorbable because it helps to remove the phytic acid content. The latter can combine with minerals such as magnesium and zinc and block their absorption. Whole grains are effectively seeds so they contain enzyme inhibitors which are activated by water and warmth in preparation for growth. Soaking in essence pre-digests the grain making it’s nutrients more readily available.
I personally soak brown rice overnight if possible with water and a dash of lemon juice or apple cider vinegar. Even a few hours is helpful if I forget the night before. I am constantly surprised when discussing this with my older clients how many will tell me that their parents used to do this. We seem to lose many of our food traditions with the speed of modern life.
7. Leftovers
Cool quickly and store in fridge within an hour of cooking. Eat within 24 hours or you can freeze it. Defrost it in the fridge and reheat thoroughly.
There are two major forms of vitamin D from two different sources.
Vitamin D3 (cholecalciferol) is our main source (80-90%) and it is produced in the skin following sunlight exposure but it is also found in foods of animal origin. Technically this makes vitamin D a pro hormone.
Vitamin D2 (ergocalciferol) is found in foods of vegetable origin and supplements
In the UK our main dietary sources of vitamin D are food of animal origin, foods fortified with vitamin D and supplementation. Naturally rich food sources include egg yolk and oily fish such as salmon, mackerel, herring and sardines.
Absorption
We probably absorb between 62 to 92% of our dietary vitamin D. It is fat soluble and absorbed in the small intestine from where it is transported via the lymph into the circulation. Vitamin D produced under the skin enters the fluid between our cells (extracellular) before defusing into the circulation and being transported to the liver.

Vitamin D content is taken from British Nutrition Foundation ‘Vital vitamin D’ resource sourced from McCance and Widdowson's The Composition of Foods: Seventh Summary
Total vitamin D production depends on a combination of factors:
Intake via the diet and from sunlight
The amount of vitamin D absorbed and then delivered to the liver
The amount produced by the liver
It’s half-life in plasma.
Uptake by body fat and muscle mass.
Rate of conversion to other metabolites
Levels of acute inflammation in the body appear to adversely affect vitamin D levels.
The body appears to store vitamin D in adipose tissue (fat cells) and possibly muscle tissue. Studies suggest that levels of vitamin D decline as our body mass index (BMI) increases, and increase as BMI decreases. However the ability of the body to access these stores is unclear and it may be sequestered rather than stored.
There are in fact, a whole lot of factors that affect how much vitamin D our bodies can make including:
how much skin we expose to the sun
the height and angle of the sun in the sky
the time of year
the duration of exposure
the health (and age) of our liver and kidneys
excess weight
Role in the body
The main role of vitamin D is to help regulate the absorption and metabolism of calcium and phosphorus from the gut. To a lesser extent it also regulates magnesium absorption.
Vitamin D is therefore vital for bone mineralisation, bone growth and bone health. Without it bones will be soft, malformed, and unable to repair themselves normally. This results in the disease called rickets in children and osteomalacia in adults. Vitamin D also plays an important role in musculoskeletal health and neuromuscular function because of its’ role in calcium homeostasis.
However evidence is emerging of other roles for vitamin D including:
Appropriate muscular function
Better brain health and improved mood
Stimulation of anti-inflammatory pathways
Good gut function
Proper functioning of the immune system (immune-modulation)
Prevention of acute respiratory infections
Optimisation of blood sugar levels and weight loss
Cardiovascular health
Healthy pregnancy and reduction in pre-eclampsia risk
Reduction of cancer risk, heart disease, autoimmune disease and osteoporosis
Healthy aging
Latterly, more data is emerging for post-covid vaccine support
Measurement
Both vitamin D2 and vitamin D3 are converted by the liver to 25-hydroxyvitamin D written in shortform as 25(OH)D and then to the active hormone 1,25 dihydroxyvitamin D. Tests measure 25(OH)D to estimate the status of vitamin D in the body because it is the most useful indicator. It remains in the blood longer and is present at much higher concentrations than the active form.
The National Osteoporosis society (NOS) guidelines (UK, 2013) and the Institute of Medicine (US) classify vitamin D results as follows:
Less than 30 nmol/L is deficient
30-50 nmol/L may be inadequate in some people
Greater than 50 nmol/L is sufficient for almost the whole population.
The Scientific Advisory Committee Report (SACN) report (2016) considers levels in the UK below 25 nmol/L to be inadequate with an increased risk of rickets and osteomalacia.
However the Endocrine Society Task Force concluded 50 nmol/L as the cut off for deficiency and recommended that concentration “should exceed 75 nmol/L” for maximum benefit on calcium, bone and muscle metabolism. Other researchers have proposed thresholds between 50-120 nmol/L to reduce the risk of adverse non-skeletal outcomes.
Dr Damien Downing, president of the British Society for Ecological Medicine and vitamin D expert, recommends a vitamin D blood level of at least 75 nmol/L for immune support and levels over 100 nmol/L to lower your risk of cancer and autoimmune disease. Grassroots Health (vitamin D global expert Group) suggest anything below 100 nmol/L is inadequate and recommend optimum levels of 100-150 nmol/L.
Your magnesium and vitamin K2 intake can also influence your vitamin D absorption. Magnesium is required for the conversion of vitamin D into its active form. If your magnesium level is too low you may store vitamin D in its inactive form.
How to supplement if blood levels are low
Low blood levels of vitamin D may mean that you are not getting enough exposure to sunlight or enough dietary intake or that there is a problem with its absorption from the intestines.
In the UK most people should be able to obtain enough vitamin D from sunlight from the end of March to the end of September.
During autumn and winter as many of us don’t get enough sun exposure a supplement may be required. The best way to determine your requirement is to measure your vitamin D (https://www.vitamindtest.org.uk/) level and then use the Grassroots vitamin D calculator to work out the correct dose. https://www.grassrootshealth.net/project/dcalculator.
Grassroots Health also suggest taking 600mg of magnesium and supplemental K2 of 90 mcg for women and 120 mcg for men daily. This helps to support bioavailability of your vitamin D as well as conversion to the active form.
Elderly people, those with darker skin tones, overweight or obese individuals or those exposed to limited sunlight have a much higher risk of becoming deficient. The Department of Health and Social Care recommends a daily supplement containing 10 micrograms (400IU) of vitamin D for higher risk groups like these.
You can also get some idea of where your level might be by using the D Minder Pro app from the App Store. This app is expertly designed to help you track and manage your vitamin D levels. It also provides other useful data related to your geographical location.
How much to supplement
Official recommendations on how much to supplement vary widely. In the UK it's 400 IU (international units) or 10mcg (micrograms). The EU and many countries go for 400-600 IU, the exception is Italy's 2000 IU (50 mcg), in the USA its1000 IU (25 mcg). Some vitamin D researchers and experienced clinicians, such as Professor Hollick, recommend 4000 to 5000 IU (125 mcg) for daily maintenance. A general guideline for adults over the age of 18 is between 50-100 mcg (2000 – 4000IU) for the colder months. It is recommended to work with a healthcare practitioner before supplementing at these levels.
Which form of vitamin D to supplement
Clinicians usually recommend vitamin D3 for supplementation as D2 isn’t so effective at raising vitamin D levels in the blood.
Toxicity
Commercially vitamin D is synthesised by UVB irradiation of 7DHC (from sheep wool) and ergosterol (from fungi). Prolonged sunlight doesn’t cause excess production but high dose supplementation can be toxic and can cause hypercalcaemia (soft tissue deposition of calcium). High levels will usually reflect supplement intake.
To evaluate how your sun exposure and/or supplement dose is working for you it’s a good idea to re measure your vitamin D level after three to six months.
N.B. 1 microgram of vitamin D is equal to 40 International Units (IU). So 10 micrograms of vitamin D is equal to 400 IU.

Intermittent fasting and fasting for health
Intermittent fasting is in the limelight at the moment but many traditions have been incorporating fasting for millennia. Humans have historically fasted overnight, for religious reasons or during periods of food scarcity. Some monks have a precept called ‘no meals after noon’ and religions such as Taoism, Sikhism, Hinduism, Christianity, and Buddhism all fast.
Fasting principles
What we eat at mealtimes is our primary fuel source for 3-4 hours. After 4-12 hours we utilise sugar (glycogen) stored in the liver, muscle and brain. Somewhere between 10 or 12 hours we will start to burn fat out of the liver to produce glucose for energy (gluconeogenesis). It takes 2-3 days for fat to become the predominant fuel source.
The body will often store toxins in fat cells waiting for an opportune moment to detoxify. It’s a bit like us putting things in cupboards, pending a rainy weekend for a clear out. When we are constantly digesting this moment doesn’t materialise. The body never gets chance to undertake any longer term regeneration or deep cleaning projects and our cells and guts can become overwhelmed.
"fasting is the body's equivalent of spring cleaning your house or servicing your car"
The digestive system
The inside of our gastro intestinal (GI) tract is still considered external to the human body. The cells lining the GI tract act as the gatekeeper to our body’s internal environment. The lining is delicate about half the width of a human hair. Nevertheless it underpins all of our health by protecting our immune system and blood stream from toxins and pathogens. The lining is covered in a mucus layer which contains our gut flora (microbiome) and this forms a selective barrier between us and the outside world.
Host microbiome axis: Interaction between the GI tract, the mucus layer and our immune system
Source: Esser, D. et al. (2019) Functions of the microbiota for the physiology of animal metaorganisms; Journal of Innate Immunity; 11(5), pp. 393-404
The immune system
Just behind our gut lining sits our gut associated lymphoid tissue (GALT) which is host to the majority of our immune system. Most people eat at least 3 meals a day plus snacks. This means our immune system is on duty 14 hours a day assessing anything that filters through the gut lining for potential toxins and pathogenic material.
With constant stimulation and no rest, our immune system can’t build up reserves of antioxidants or take care of any long-term building projects. It then risks developing faults or errors of judgment which scientists believe can make us susceptible to:
Gut inflammation
Food sensitivity
Asthma/eczema
Allergy
Autoimmune issues
Diabetes
Cancer
Types of fasting
There are a number of different types of fasting (see below)*. There are also hybrid diets such as the fasting mimicking diet (FMD). This is low in calories and protein but high in fat and maintains micronutrient content. Time restricted feeding (TRF) when food is kept to an eating window of 12 hours (7am to 7pm) or 8 hours (8am to 6pm) will provide an overnight fast of 12 and 14 hours respectively. These variations may be more suitable for some people depending on their state of health and unique physiology.
Longer fasts of up to 5 days can promote autophagy which is a process of programmed cell dissolution. This takes place once all of our glycogen stores have been utilised c. 24-72 hours around the 4th or 5th day. With this process the body breaks down any damaged cells such as mis-folded proteins, ameloid plaques, damaged DNA etc. It’s a process of self-eating where the body recycles damaged materials for alternative use. Shorter fasts such as Intermittent fasting help the body to train into longer fasting periods. Fasting shouldn’t be undertaken without due consideration of your current health status and reference to your health practitioner or GP.
“You get rid of the junk during starvation — and once you have food, you can rebuild… The damaged cells are replaced with new cells, working cells — and now the system starts working properly.”
Dr Valter Longo
What fasting does
Your autonomic nervous system (ANS) carries out all the functions which basically run your body on a day to day basis. Fasting seems to press the reset button on your physiology and all the functions of your ANS including:
Gut / immune system reset - fasting appears to reset our metabolism and rejuvenate the immune system as it gets chance to rest and recover and restore our antioxidant reservoirs.
Gut hormone/stress reset – fasting resets our hormonal systems and avoids the constant adrenaline state to which so many of us have become accustomed.
Gut / brain reset – fasting can help to change our emotional relationship with food as we challenge the body to adapt to different levels of food supply.
Liver reset – fasting facilitates detoxification as we burn fat and sugar out of our liver compartments.
How fasting improves health
Studies in humans and mice of different types of fasting demonstrate improvement in multiple health indicators such as:
Weight loss
Reduced insulin resistance
Lower insulin levels
Decreased oxidative stress

My approach and cautions
I don’t introduce fasting until I believe the client is sufficiently healthy to follow the protocols safely. My approach is personal to each client. Before starting to restrict food intake we work to ensure that they are well nourished from a micronutrient perspective, have a well functioning liver and detoxification pathways and are hormonally stable. In addition they will preferably be trained in the breath-work I teach. This helps clients to work with their autonomic nervous system to manage their stress levels and emotional state in general, but also around food.
We typically start with 2-3 days of intermittent fasting. Usually it’s from the last evening meal at around 7 pm until about 1 pm or lunchtime the next day. This provides an 18 hour break for both the digestive and the immune systems.
Hydration is also important. I have a specific hydration protocol for clients to follow when they are preparing for or undertaking a fast or intermittent fast. There are some contraindications to fasting so I always recommend working with a health practitioner.
What the research shows
Most of the research is currently in mice but it seems to demonstrate:
There are metabolic benefits from fasting including time restricted feeding even if no weight loss is recorded.
As well as quality and quantity the timing of food intake appears to be a key parameter for nutritional and metabolic health. Circadian rhythm and metabolic processes are linked and their disruption can lead to weight gain. Gut bacteria appear to have their own circadian rhythm and fasting benefits this.

Please note: This article is intended for information purposes so readers can gain an understanding of the benefits of fasting for health. I highly recommend working with a health practitioner if you plan to try this as there are many aspects to take into consideration.

Fed up with snoring?
Nighttime snoring can range from being a mild embarrassment and nuisance to a more serious chronic problem. It can sometimes be a potential indicator of more serious health issues such as obstructive sleep apnea (OSA). There are essentially two reasons snoring can happen, either breathing is too forceful or the upper airway is too narrow.
During sleep the tissues of the throat relax which can partially block the airway. This tissue vibrates as air flows past it and it is this vibration and turbulence in the airway which leads to snoring. The more this airway narrows the more forceful the airflow becomes increasing vibration and therefore the snoring volume. There are two types of snoring mouth snoring and nasal snoring.
Mouth snoring
If you wake with a dry mouth then you are probably mouth breathing during the night and this won’t refresh you properly. If you mouth breath during the day you will build neural pathways regarding this behaviour pattern which will continue during sleep. This can often be a habitual pattern rather than an anatomical requirement especially where children are concerned. To re-establish full-time nasal breathing Patrick McKeown founder of The Oxygen Advantage breathing programme and author of the book by the same name recommends using lip tape. You can use any tape suitable for skin contact such as Mircropore but if the idea of covering your mouth with tape is stressful you can use MYOTAPE. This tape uses elastic tension to bring the lips together without covering the lips completely. You can purchase this tape here https://myotape.com. It may seem rather alien but a new 2020 study revealed that even full-time mouth breathers could often lip-tape providing there wasn’t any nasal obstruction. They also concluded that in children full-time nasal breathing is critical for craniofacial and airway development.
Nasal snoring
If you are nasal breathing during sleep but still snoring then this can be due to a number of different reasons summarised below.
The way we breathe during the day affects the way we breathe at night which affects how we sleep and whether or not we snore. The lower and upper airways are mechanically connected. Diaphragmatic breathing tones and opens the throat area minimising the risk of collapse to cause snoring. The exercises I teach look to reset the day to day breathing pattern. When we breathe light and well during the day we can also breathe light during the night.
The exercises
The breathing exercises correct dysfunctional breathing patterns and help to:
Decongest the nose
Retrain nasal breathing during the day and night
Recalibrate the breathing centres in your brain
Improve lung volume and activate the diaphragm
Stimulate your vagus nerve and activate your parasympathetic nervous system
Reduce stress hormones
Insomnia
There is a lot of crossover between snoring and insomnia. Insomnia affects between 25 and 30% of the general population and for about 10% this is a chronic complaint requiring medical help. Insomnia is linked to many health complaints such as hyper arousal of the autonomic nervous system (ANS), stress, irritability, daytime fatigue, anxiety, emotional dysregulation, difficulty concentrating, depression and even high blood pressure.
Obstructive sleep apnea (OSA)
If OSA is present or if chronic snoring progresses to OSA this can lead to more serious health consequences. If you suspect OSA you should consult your GP who will probably recommend a sleep study to identify if OSA is present and if so which type.
