No. On our program because you are eating in a specific scientific way, each time you actually consume 200-300 calories you actually turn on your digestive system which causes your body to burn 160 calories just while it is digesting your 200-300 calories, which then activates the "T-REX" to go and eat another 300-500 calories of fat out of your body. The happens because you intentionally under ate through your mouth you have activated the fat burning mechanism that we affectionately call the "T-REX" to go and eat even more fat. (release the T-REX beast!!) :)
