A low-glycemic meal plan that contains approximately 100 grams of protein is a great way to balance your blood sugars. Protein does a great job of helping you feel fuller for longer, which is especially helpful when cutting calories and limiting your carb intake, which in turn decreases how much fiber you're getting. So what can you actually eat on a high-protein, low-GI meal plan? Thankfully, there are plenty of delicious, healthy foods to fill your day with while following this eating plan.
