The best thing you can do for your weight is to gain a few pounds—of muscle! Muscle burns more energy than fat, even when resting. Five extra pounds of muscle lets you eat 375 more calories in a day and not gain weight. If you maintain your calorie intake, energy for new muscle will come from fat stores, so you will actually lose weight. Don’t be fooled by what the scales say. When clothes start fitting better but the scales show you weigh more, you’ll know the fat that was formerly there has been replaced by muscle elsewhere. Muscle-strengthening exercises include weightlifting, leg-lifts and standard pushups. If you have the space, invest in home exercise equipment.
