"i am not extremely obese, but at 5&#039;7&quot; and my higest weight at 175lbs since having children, i just feel large. i also have hypothroidism (on synthroid). i tried medifast (bad) and nutrisystem (3 months, lost 15 pds) but they discontinued my favorite foods and i got tired of the same 10 dishes. i gained it all back. i did the gym (weights and cardio, 1 hr a day x 4 days a week, for about 5 months). exercise just makes me hungry, so i over eat and only lost like 2 inches and 10 pds. went to a doctor and (after tests) got prescription for phentermine. only moderately curbs appetite for me and gives me dry mouth (but that helps me drink lots of water). exactly 2 weeks so far and went from 170lbs to 165lbs. not bad, we&#039;ll see if it lasts."
