I reached a goal weight when I was around 20 yrs old through a low carb diet and went to a normal, healthier diet and kept it off for about 2yrs. I gained it all back and then some, but during the time I was thinner, I felt like some things were better and as good as I thought - I could wear a bikini and get attn from boys like everyone else, I could run pretty fast and stick with it and stay motivated b/c I was looking good as a result. I too thought I was still fat at the time, but I look back at those pics and think, darn I looked hot!
I am not as heavy as I've ever been, but I am still about 15-20lbs heavier than I was at my goal. Like Carolyn, I am watching what I eat and working out quite a bit, but not doing anything per se. I am considering Nutri-system for the last 10-15lbs, but I don't know if I want to spare the expense. I know what I need to do and I am healthy now, just want to get to a little healthier weight (I am technically overweight).
