When you eat small amounts of carbs, your body gets wacky – your muscles start craving more carbs but it’s okay because it has more potential to utilize them correctly instead of just putting them in your fat deposits. This way, when you start eating more carbs again, they will go straight into your glycogen stores in your muscles, which means you will look buffer and better. This starts a chain reaction that ends with your muscles creating more muscle tissue due to protein synthesis, so reducing the amount of carbs for a few days can be very beneficial to your body. However, make sure that you eat more protein to protect yourself from muscle breakdown, which can be caused by a lessened carb intake.
