Welcome to our forum,

Unexplained weight gain is a clinical symptom of hypothyroidism. Exercising also reduces the main thyroid hormone T3 (liothyronine) which is needed in all the billions of receptor cells in our bodies. It is needed to drive our whole metabolism.

Have you had a Full Thyroid Blood Test, GPs might ask for more than TSH but some labs wont do so if TSH is 'in range'.

In range doesn't make sense to most of us as the doctors ignore clinical symptoms which used to be known by doctors before blood tests were introduced.

A blood test for thyroid hormones should be at the very earliest possible and fasting (you can drink water). This is because the TSH is highest and it drops throughout the day and may mean the difference of being diagnosed or not.

If GP wont do more than TSH, T4 you can get a private blood test taken and I'll give you a link. If you quote Thyroiduk's code you will get a small discount. You should also get thyroid antibodies checked.

GP should do Vit B12, Vit D, iron, ferritin and folate. This is an explanation of thyroid hormone blood tests:-

Always get a print-out of your blood test results with the ranges (labs differ) and post for comments. This is a list re hypo:-

Thank you so much i will do


There is an Italian/American Naturopath who specializes in this problem and is currently writing a book on it.

Look up Elizabeth Bright

She is very kind and will occasionally do skype.



If you are hypo, you need to eat more than 1200 calories a day. Eating so few calories will not make you lose the weight, and will probably make you put more on, because it has an adverse effect on T4 to T3 conversion.

If you are hypo, your weight gain has nothing to do with eating too many calories, so cutting back on your calories cannot make you lose the weight. What you need is optimal levels of T3. So, imperative to get those thyroid hormone labs done!

Also, if you have nutritional deficiencies - which you very well might do on so few calories - you will find it difficult to lose weight. So, ask your doctor to test vit D, vit B12, folate and ferritin to give you a base line. These all need to be optimal for you body to be able to use thyroid hormone, whether it's the hormone one makes naturally, or the hormone with which we supplement. :)
