I explain it in this simple way - Our bodies use sugar (most of which comes from complex carbs) as fuel. When we cut down on that available fuel, the body turns to fat to burn. First the fat we eat, and second the fat on our bodies. The body actually runs more efficiently on fat than on carbs.

Our ancestors (before agricultural - which is where most of the time has been spent) did not have access to complex carbs, and fruit was available only during the short time it was in season. Processed sugar was unknown. They existed on meat, preferring the fatty parts, and green type plants they found growing. The few carbs they did eat came from roots.

Our bodies have not evolved quickly enough to cope with the massive amounts of sugar we consume. Bread, pasta, potatoes, etc. are converted to sugar in the body. Because we are using sugar for fuel, the fat we consume becomes fat on our body. We need to change that and start burning fat as fuel as we were meant to by mother nature.

I do believe that the obsesity and diabetes epidemics are caused by sugar consumption - in all its forms. Unless we get back to basics - we will just keep getting fatter and sicker.

Good Luck - Orchid
