Natural diet

My friends noticed that my dad lost weight. Well, it's noticeable because his tummy went away and he looked slimmer now compared from before. His doctor advised him to take weight loss supplements, like xenical to get rid of all those fats in the tummy. All in all, he lost 25 lbs. I love to take xenical but I just don't have the budget for that, so doing the natural way to loose weight. Jogging and exercise.
