Weight training helps women lose body fat and build lean muscle. Lean muscle speeds up your metabolism so that you burn more calories through out the day. Your clothes will fit better because you will be losing inches. It will also strengthen your bones, which can help reduce your risks for osteoporosis later in life. So, along with aerobic activity, women need to include weight training.
Some people think that high protein diets help burn fat and lose weight.
People who do lose weight on these diets do so because of water loss, not body fat loss. The body can not store extra protein so it must either use it or lose it. If you eat more protein than your body can use, the protein is broken down and part of it is either used for energy or stored as body fat. The other part, the nitrogen part, can be toxic to the body in excess amounts. Also diets high in protein are usually high in fat and calories.
