I'm new here. I would like to lose weight. I have an underactive thyroid which I currently take thyroxine for I am a healthy eater and active but I find my weight just creeps up. I weigh 12stone 5lb and my height is 5' 5" I used to be around the 10stone mark. I have tried dieting I lose the weight when I do lose it I feel really good about it, but then it starts to come back on and I find I weigh even more than before the I comfort eat which does not help. I do exercise and I am active. I just wondered if anybody else finds it difficult to lose weight and keep it off after being diagnosed with an underactive thyroid. I've been to weight watchers etc but none of that has really helped me maintain my weight loss.
