Quantum Metabolic Nutritional Therapy

Do any of these ring true for you? 
  • Are you struggling with brain fog, depression, anxiety, sleep, mood swings, anger or irritability? 
  • Do you struggle with your weight or binge/compulsive  eating?
  • Are you disillusioned or confused about current medical and nutritional advice?
  • Are you on medication you feel is doing you no good? 
  • Do you have/are worried about developing diabetes or dementia?
  • Are you following a way of eating but not getting the health benefits you expected or are experiencing unusual symptoms? 
  • Are you interested in a medical low carb,  ketogenic diet or elimination diet but want to be guided?


Hello I’m Sara and I help people improve their metabolic health, physical health and mental health and metabolic issues using low carb or ketogenic nutrition along with quantum / circadian biology. 

I found that fixing my body clock and  with my way of eating was what healed my metabolism and mental health. 

I spent 20yrs looking down every rabbit hole you can imagine.  Movement, neurology, supplements, diets, medications, machines etc. 

WHEN you eat can be just as important as WHAT you eat. 

Diet is MORE than just food and I look at other factors in your life that other people overlook that affect your metabolism, mood and hormones. 

I give you information, answers, support  and guidance you need to take control of your health.

  • WHY is my body malfunctioning?
  • WHAT is on offer  beyond medications or operations to help restore it to good health?
  • HOW do some people easily lose weight, overcome mental health problems or reduce/pain inflammation on certain diets? 
  • WHICH hormone imbalances can lead to obesity or depression, even when we eat ‘healthy’? 

If you have a persistent health problem, then a combination of quantum biology which is your ENVIRONMENT  and professional advice on your WAY OF EATING is the best place to start.  

We have often gone on holiday or know others who go away and suddenly feel much better even though we ate MORE food.  

The underlying biochemical and biophysical issues with mental and physical health are to do with the following 

  • Circadian rhythm or body clock out of balance (Your brain and body doesn’t know what time which is very stressful and linked to depression, cancer and diabetes. It is so doesn’t know if you are meant to be burning fat, relaxing or healing) 
  • Neuro transmitter imbalances (Brain chemicals and mood all over the place)
  • Oxidative stress and inflammation (Damage to cells, accelerated ageing. Depression, anxiety and chronic pain strongly linked to inflammation) 
  • Poor mitochondrial function (Cells not able to produce enough energy, make exclusion zone (EZ water) or burn fat properly)
  • Cerebral glucose hypo metabolism (Poor glucose use in the brain brain fog)
These CAN BE FIXED BY FIXING YOUR BODY CLOCK AND WAY OF EATING It is much easier than you think when you have professional help and support

My areas of expertise include:

How to ensure your ENVIRONMENT is optimised so you can have more ‘wiggle room with your diet’ as its very easy to get obsessed with food and make yourself worse. (I did that) 

The biophysics of our body is always overlooked and by taking a quantum approach I was able to lose 15lb without painful caloire restriction, get at least 8 hrs of quality sleep per night, energy to work 10hrs a day with no mood swings and  no aches and pains. 

I offer dietary advice on the following as I have done them all over the past 20yrs. 

  • Quantum / Circadian 
  • Paleo
  • Low-carbohydrate
  • Ketogenic
  • Cyclical Ketogenic
  • Carnivore
  • Fasting 

To learn about the benefits of low carb diets and how they help your mental and physical health go to ‘7 Reasons To Try a Low Carb Diet‘ 

If you are considering a low carb or ketogenic  but want to know if its safe, please go to ‘Is The Ketogenic Diet Safe’

I am Quantum Biology certified which is key for helping you with hormone imbalances, sleep, mental health and unexplained weight issues. 

I trained in ketogenic metabolic therapy AKA how do medical keto diets with adults and children with Beth Zupek-Kania RDN, CD (30yrs with keto diets)  and Denise Potter RDN, CSP, CDE (31 yrs in practice). 

I also did a CME-approved course  with Dr Georgia Ede who is board certified psychiatrist specialising in ketogenic diets for psychiatric conditions and insulin resistance.  

My background is biochemistry and I was a research scientist for 10yrs. Lab work requires  understanding the science, attention to detail, making observations, planning, practical work and trouble shooting. 

I have been a hypnotherapist since 2012, so I support you psychologically with your diet changes so you get the best results. 

The conditions I work with are:

I am very familiar with the medication often used in the above conditions, although you need to talk to your prescriber about altering your medication (if you use any) as a medical ketogenic diet or even a paleo diet often means some people reduce or come off their medication.

I am not a medical Dr so I cannot give your advice on medication or medical advice.

I know about other conditions so if yours is not on the list please ask as I might be able to help. 

“I cannot recommend Sara highly enough for advice and support on the keto diet and different types of fasting. As a life long calorie counter and a member of Slimming World for many years, I struggled to get below a certain weight. Feeling demoralised, I decided to take a totally different approach and asked Sara for a consultation and ongoing support.

Sara was with me every step of the way. Her qualifications and knowledge were particularly important, as I knew her advice was based on her in-depth understanding of the ketogenic lifestyle.

Sara provides a personalised consultancy, depending on individual needs, rather than a standard programme.

I now have the skills and confidence to maintain weight loss and enjoy my food so much more. Thanks so much Sara”  – Gill Wyatt
