You are overweight for the most simple of reasons -- because you're eating the wrong foods, the wrong types of calories per meal, and you're also eating meals in the wrong patterns each day.
Also, the pattern that you choose to eat your meals each day is more powerful than any prescription weight loss pills. This is true because your body is like an "engine" and it only needs certain foods at certain intervals each day, and if you don't eat the right foods at the right times then it won't burn those calories -- and you'll wind up storing those calories as fat tissue. (Hint: You need to eat more than 3 times per day to lose weight, but we'll show you the details later).
