Obesity has become a national problems, and
more than 50% of Americans are overweight. This increase the health care system burden.
We have too many food choices; when we are bored, we eat and when we are, when we have
party we eat. So the eating becomes a problem for the weight control. And because we have
so many food choices, and it really, it’s up to us to control which kind of food we
eat, we suddenly have a surgery to control the weight, it’s called stomach bypass surgery.
But this surgery cost so much money and so much problems, malnutrition and even death.
So we need to find another way to control our weight and address the fundamental causes
of weight gain.
