BetsyHi Kaye,
No...I have always been quite small. 5'2", about 105 pounds. The only time weight was an issue was many years ago when an endo I saw at the time (and quickly 'fired') put me on hydrocortisone. I ended up all cushing-like. He was happy...my levels were right on; I was miserable. Thankfully, I quickly shed that weight.
I eat whatever I want, but only when I am hungry and only until I am full even if there is still food on the plate. The only 'special' dietary need I subscribe to is an adequate supply of salty things like olives and pickles in my fridge ;-) I do avoid a lot of greasy things, most fast food, and snack foods like chips but that is because I had my gall-bladder removed about 13 years ago and my digestive/intestinal system gets very unhappy with that stuff.
