THE DIFFERENCE BETWEEN SKINNY AND FAT PEOPLE

Ever notice that there are some people who can eat anything they want without gaining weight and other people who can't? Some people manage to stay fat even without overeating.  What makes this possible? Its insulin.  The pancreas in skinny people makes a small amount of insulin and as a result they make small amount of fat. Obese people make 4-10x more insulin than skinny people and that insulin causes the fat to grow and prevents it from burning off. Insulin in fat people is even higher in the fasted state and spikes higher with meals. Elevated insulin levels shut off fat burning. Fat people simply can not burn fat because their insulin levels are high all the time.
Check out the graph. The three humps represent the insulin bump that occurs with meals, brakfast, lunch and dinner. The normal subjects have much smaller spikes with meals. Even between meals, lean people have lower insulin levels. This is it. The reason why the lean are lean and the fat are fat.

The best way to reduce the insulin spikes is to cut out carbs. Carbs strongly stimulate the pancreas to make insulin. Fat doesn't.
