Improve Energy and Metabolism

The thyroid is the most ignored gland in your body. It is situated in your neck just below the Adam’s Apple and produces hormones that affect every major organ and the metabolism and repair of every single cell and it has a major influence on hormonal function. The thyroid is one of the most important areas to look at to improve energy.

The most important thyroid hormone is thyroxine (also known as T4), which outside the thyroid is converted to T3, which is the active form of the hormone.  Basically, the more T3 you produce the faster your metabolism.  If you don’t produce sufficient thyroid hormones many systems in your body begin to slow down – heartbeat, circulation, blood pressure, energy levels, metabolism and temperature.  Slow metabolism will mean that you don’t burn calories as efficiently as you could so you gain weight more easily.  Also, when the body slows down, the body’s ability to detox is greatly impaired.  Symptoms that should make you investigate whether your thyroid may be underactive include low energy, mental fogginess, depression, cold hands and feet, weight gain even with a poor appetite, high cholesterol even when you eat sensibly, a slow pulse, low blood sugar, headaches, infertility, dry and sometimes puffy skin, brittle nails, poor vision, thinning hair, low libido and heavy periods.  Phew!

An underactive thyroid is seven times more common in women than in men, unfortunately because some of the symptoms associated with an underactive thyroid are so often attributed to the menopause thousands of women go undiagnosed and are offered orthodox HRT treatment.  Further standard GP tests for TSH and total T4 are less than useless and 100,000s of people go undiagnosed.

At the London Clinic of Nutrition we take a functional approach to assessing thyroid imbalance, looking at foods that may inhibit its function, deficiencies in minerals, amino acids, fatty acids and often most importantly, we look at Iodine, stress and adrenal function.  It is very rare that people have thyroid problems without some element of adrenal dysfunction.  We then look to support the Client and improve their ability to handle stressful situations using life style changes and often herbal adaptogens.

One of the main problems with thyroid health is that if you are tested by your doctor it is very likely that they will report that everything is fine.  Unfortunately, the tests are rather crude and your thyroid would have to be very underactive indeed before it will show up as altered blood levels.  We use a comprehensive thyroid panel along with saliva adrenal hormone testing and Iodine loading  for a far more accurate picture of your thyroid health.  We also use the Barnes Temperature Test, which involves putting a thermometer under your arm first thing in the morning and recording your temperature (but please note women should ideally do this test on days two and three of their period).  Readings under 36.5 suggests that an individual has sub-clinical hypothyroidism.

Thyroid disease testimonials

I first contacted Oliver after being told by my GP I had insulin resistance, which could ultimately lead to diabetes. After a brief consultation Oliver suggested various herbs and supplements, and after taking them for six months my blood glucose levels came normal. Since then Oliver has also helped me with stopping hair loss and increasing energy levels by supporting my thyroid and adrenals. What i particularly appreciated was that he would always try and explore the less pricey options first, being mindful of saving me from unnecessary expenses.

Oliver has been assisting me (very successfully) with chronic long term complications of Diabetes type 1 and hypo-thyroidism. Over the past year, I have found my general well-being greatly improved, and the continuity of care and provision to be outstanding. There have been certain approaches, that I have found difficult to adapt, and have been amazed that Oliver has always found time to find a method that works with my lifestyle. I feel very fortunate that I managed to use a practitioner that delivers a positive result – and therefore have no hesitation in passing on a very good recommendation for this young man, to anyone that may want to try his approach.


Having read all the good reviews of the London Clinic of Nutrition, I had high hopes of healing my Hashimotos thyroid problem, I was not disappointed. They identified the foods that were contributing to my autoimmunity, reduced systemic inflammation and identified that I was incredibly Iodine deficient. After working with the clinic for 4 months, I had no signs of antibodies, no fatigue, brain fog, or constipation. I feel like I now have my life back after 7 years of battling with my health. I wish my GP took the time to listen to me in the way that Oliver the Nutritionist did. Thanks again.

Got excellent results with Oliver Barnett working to correct symptoms from Hashimotos Thyroiditis, most significantly the extreme fatigue and brain fog, hand in hand with depression, headaches, etc. I went from 3/10 energy levels to a consistent 8/10, over a 12 month time period. I now find that I can do things in the gym and at yoga that I have never been able to do before! Like any illness that has been slowly building up over years, I was not going to suddenly get better overnight. Working with Oliver, I had to make some big changes to my diet and lifestyle, some of which felt overwhelming at the time, but I was relieved by Oliver's gentle approach to this - the odd lapse was allowed, and actually knowing that made it easier to stick to the new regime. We identified the food intolerances that were holding me back, I invested in several new cookbooks, and set to cooking some new things! A set of supplements were prescribed. The recovery wasn't a straight road - on a couple of occasions I found myself slipping backwards, but with patience and tenacity, Oliver worked to uncover the culprits, and I'm so pleased to say that we got there in the end! I am extremely grateful! Sarah Chatterton

Conditions that we can treat include...


My session with Oliver Barnett was very interesting and informative and he told me how to build on my existing healthy diet, broadening what I ate and how I prepared it, and prescribed a course of herbs and a detox.
