Most people avoid carbohydrates-based foods such as cereals in an effort to lose weight thinking that grain products could counteract their weight loss effort. Previous studies however do not support this assumption and has shown that eating grain products is not responsible for the obesity epidemic in the US.
According to Dr. T. Colin Campbell, a retired nutrition professor from Cornell University, said in his book "China Study" the Chinese people in rural areas eat more grain products and still more calories, but they have much lower incidence of obesity." His studies have pointed the cause of obesity in the West in the direction of the high intake of fat and animal proteins.
