Having been diagnosed with under active thyroid last year and having to take Levothyroxine- I have tried various diets but my weight still remains the same-I would like to lose two stone but have remained the same since been diagnosed. I go Aqua fitness three times a week (an hour each session) and do super hula hoop at least twice a week for half an hour a session. I eat healthily as my husband has Type 2 Diabetes so have to cook carefully and do not eat junk foods. I feel now that cooking has become scientific having to look at Sat Fat, Sugar and salt intake. Whilst my husband loses weight I still struggle despite eating less than him and am constantly counting calories which I feel has become an obsession.
