With weight reduction through dieting only, people loose not just fat mass, but a little bit of liver, heart, muscle, and other lean tissue.
Metabolism slows down, when you only diet. And you don’t want your metabolism to slow down while you are dieting. Yes, you loose weight, and than you’ll gain it back.
Your metabolism rate falls with weight loss. Metabolic rate falls, in part, because it’s closely linked to how much muscle and other lean tissue you have.
The only way to counter the slow down in metabolism is to exercise more. And the best way to increase your metabolism is to strength train and build lean muscle. Muscle is natural fat-burning mechanism, it is an active tissue so it consumes energy. 1 pound of muscle requires your body to burn up to 50 extra calories a day just to maintain it.
What doe’s more muscle mean for dieters? More food.
A higher calorie allowance makes it easier to stick to your eating plan – and you get more nutrients too.
Strength training – muscle building will help you maintain the weight loss you worked so hard for. You loose weight permanently. And that’s usually the hardest think to achieve.
