Balanced meals=Balanced weight?
How you combine the foods at your meals affects how quickly that food passes through the stomach and how quickly and dramatically the blood sugar rises. If your meal is primarily carbohydrate, the stomach empties in 1-1.5 hours and the blood sugar shoots very high very quickly. If you add protein to your carbohydrate, you meal hangs around the stomach for about 2.5 hours and the blood sugar response is slower and not quite as high. Adding fat (focus on quality fat--olives or olive oil, fish or fish oil, avocados and nuts) to your meal provides for the meal to retain in the stomach for up to 4 hours (hence less hunger) and blood sugar response is much slower and lower.
The down side to controlling hunger and keeping our insulin response to meals in control by balancing our meals with carbohydrates, protein and quality fats... can't think of one.
