Absolutely not. Lifting weights will not only help you lose weight, but maintain the loss. Here's why:
- Muscle keeps your metabolism revved up, burning calories, fat, and glucose (sugar).
- When you lose weight, up to 25% of the loss may come from muscle, resulting in a slower metabolism. Weight lifting will help preserve or rebuild any muscle you lose by dieting.
- Muscle helps you with aerobic exercise. The stronger you are, the better you will be at any aerobic activity.
- Weight training improves your body's muscle-to-fat ratio (you end up with less body fat and more muscle), which improves both your health and your fitness level.
- Gaining muscle will help you look better as you define and tone your physique.
- Building strength helps you feel good about yourself. Although the scale may show a slight weight gain when you start lifting weights (usually five pounds or less), you probably won't look heavier because the gain is in muscle, and your clothes may even fit more loosely.
