Here is what you do. Eat 8 Walnut halves about 20 minutes before you meal and then drink a glass of water.
According to a Harvard study Walnuts can pretty much slash overall hunger signals in your brain.
There is also evidence to suggest that Walnuts may help increase fat burning.
The other thing that helps, is that the fat in the Walnuts activate the pyloric sphincter muscle in the bottom of your stomach that holds food in so that you can digest it. This will help you feel fuller with your meal.
Plan on this taking about 3 days for the full effects to kick in. Fats Rule!
