Insulin plays a very important role in your body and is key for recovering from exercise, muscle building, and maintaining optimal blood sugar levels. However, when carbohydrate intakes are high and insulin is left to run wild in the body, it can inhibit the breakdown and burning of stored fat. Insulin and carbohydrates are very tightly linked. The more carbohydrates you eat, the more insulin will be released.
To optimize insulin for fat loss, aim to get most of your carbohydrates from vegetables and some fruit. Limit grains and starches to smaller portions directly after exercise.
