Hi, I'm 17. I danced intensively for a long time, so I have a very muscular body. I am 5'7" and right now I weigh about 137 lbs. This is the most I have ever weighed. At my height, I have weighed 118, 125, and 133 pounds when I was exercising different amounts. I have hypothyroidism (Hashimoto's). My question is in a couple parts. I am never hungry. Ever. But I crave the taste of food, so I eat, but I am never hungry when I eat, and I don't really understand why. Second: even though I have a thyroid problem, I have a very easy time gaining and losing weight. For example, if I just eat sparingly, I would lose 5 pounds by the next day sometimes. I don't really know how I should be eating, or when, or how often. Any info/thoughts/ideas you have would be great. Thanks.
