There is a pandemic of obesity and diets will not solve the problem because they are not scientifically sound. Our cells know what they need in our diet and if they don't get it they send messages to our appetite center saying eat. However, what we eat is not what we need; it is fast food that is relatively devoid of the nutrients we need. Environmental toxins also interfere with burning fat. When we are exposed to these toxins it interferes with fat burning, so we have a predisposition to store fat and not burn it.
