Eat Less Carbs on the Days You're Inactive To prevent a weight-loss plateau, eat less carbs on the days when you're inactive. Eating carbs is important for recovery and energy, but if you eat too many calories, you can actually end up gaining body fat. Eat less fruit on this day, don't have protein shakes, eat lots of lean proteins with green veggies, and eat healthy fats. Image Source: POPSUGAR Photography / Maria del Rio
