You have been on every fad weight loss plan diet. Initially your weight loss is quick, but then you gain it back and find yourself heavier than before.

This is the dreaded cycle of yo-yo dieting. Yes, in the short term you can lose weight, but every time you do this you may be doing more damage than good because your body thinks it's experiencing a famine.

In response to that famine, your body goes into survival mode and conserves energy by slowing down your metabolism. Your body does its best to hold on to the fat you have for as long as it can.

So, with many diets the weight you initially lose is from fat and muscle. And that loss of muscle slows down your metabolism even further because muscle burns calories. Muscle=Metabolism.

There are also common challenges, emotional and other physical ones that come along with dieting. Many diets or weight loss programs are too restrictive or monotonous, or leave you feeling deprived and don't teach you how to permanently change your eating and exercise habits. They leave you feeling hungry, tired, and craving the foods you miss most.

You've about had it, so you return to your old eating habits and gain the weight back. And the sad part is, the weight you put back on is fat weight.

If you really want to lose weight you need a weight loss plan that is powered by leucine to help preserve muscle while you lose weight from fat. Leucine is an amino acid that heads straight to the muscle where it initiates protein synthesis (the process of building muscle). That is why many professional and Olympic athletes take it as a supplement. Preserving muscle mass also prevents your metabolism from dropping.

But how do you know which weight loss plans with leucine are the best? A good weight loss program that contains leucine should be scientifically formulated to help you lose weight, lose inches, and break the cycle of perpetual dieting. That means they should have scientific studies and tests that are published in scientific journals to show the effectiveness of their product.

To get published in a scientific journal, your findings must be agreed upon by the scientific community as a whole. Many companies hire their own scientists to perform tests on their weight loss products, come up with bogus results that they release themselves.

A good weight loss plan is designed for real life, so it should also addresses the physical and emotional challenges that come along with your weight control efforts. Proprietary formulas, should also be provided with your weight loss products so you can control your hunger, boost your energy, and keep you feeling satisfied. Plus, you should also get healthy personalized menus, specific to your body's needs and your individual preferences.

Along with any diet or weight loss plan that includes leucine, you should also exercise regularly, and eat as many raw fruits and vegetables as possible. If you follow these recommendations, you should be able to naturally, and safely lose weight and keep it off.

Good luck on your journey towards health and wellness!
