Don't forget that muscle weighs more than fat. Post surgery, I lost about 7 pounds very quickly - mainly muscles in my legs. I'll never forget looking at my legs on the leg press machine first day in the gym & thinking "Whose skinny legs are those?"

Also, "thin" women can have a higher body fat percentage than normal weight women. Fat doesn't need any calories to exist. Many women gain & lose the same 20 pounds over & over - except that each time it gets harder to take off because metabolism is all messed up.

Muscles need 50 calories/day/per pound to exist. It pays to get into the weight room. Your bones will get stronger, you'll get definition and you'll be sprinting up hills before you know it!! AND - (here's the best part) your metabolism will be raised throughout the day so you can toss back that extra Hershey's kiss (or two...three.. ) and not feel guilty - or think "I'll ride it off tomorrow."
