It’s a common advice that if you’re going to eat a carb-heavy meal, do it after a workout, or in the morning. The reason is that your carbohydrate ‘stores’ are emptier than, and the carbs go towards filling those stores, instead of being converted to fat. There’s a simple trick to emulate this effect, without a heavy workout and without fasting – just hold a squat position for as long as you can, until you feel a painful burn.
Since the leg muscles are the largest muscles in the body that you can flex and keep tension on easily, their glucose receptors ‘open up’. This means that a large percentage of the carbs you eat will go in those muscles and be converted to energy in the mitochondria, instead of ‘spilling’ around your body and going to bad places, like the belly.
