Having lost 50 lbs and kept it off for a year and half, my advice is set a goal for your weight loss, reach it safely, and then reward yourself with a new kilt. Weightloss like getting a new kilt, (unless you order it from Rocky,) is an exercise in patience and self control. Lose the weight and you'll be happier and healthier, as well as look even better in your kilt! Best Wishes!!
