To save some time, here's the gist of the clip I saw:

--eat a tablespoon of almond butter with a big glass of water 30 minutes before a meal.
--supposedly this slows down the entry of carbohydrate foods into the pyloric valve at the lower end of the stomach.
--supposedly this prevents immediate blood glucose rush and the consequent quick rise and quick drop in blood sugar.
--that means you won't eat as much at the meal and carb cravings are prevented

The theory is that 100 calories of almond butter will prevent the consumption of 500 calories of pasta.

Believe that?
