True, its much easier to find someone or something else to explain their portly predicament, but this will rarely result in weightloss. BTW... This is a fun thread!
Actually, the only sacrifice it takes is not eating high glycemic carbohydrates. A low carb, high protein eating plan, combined with moderate exercise, will get the weight off.
If you want to KEEP IT OFF, you've got to decide you're going to eat and exercise like that for the rest of your life.
If you like vigorous exercise, you should keep right on doing it.
But it's simply not true that losing weight requires hard work. It doesn't. It requires discipline.
Most Americans don't have time to work out two hours a day, and they won't, no matter what anybody says.
