Eat protein at every meal
Want to control your blood sugar and your weight? Get enough protein. 20 to 30 percent of the calories you eat should come from protein. Protein has little or no effect on your blood sugar, so any time you mix protein-rich foods with carbohydrate-rich foods, you automatically lower the GL of each portion.
But protein has other benefits. It helps keep hunger at bay between meals. And if you're trying to lose weight, taking in more protein will help your body hold on to its calorie-burning muscle tissue so the weight comes off more easily.
