Like mentioned before it is very important to follow this diet like it is written above, if it is altered in any way it may not work for you.
Now you will learn why this diet is not healthy. First of all it makes you lose weight faster than the body can burn fat. Even if you drink a lot, the weight loss will consist of 20% fat, 40% water and 40% lean muscle. So let’s say that you lost 5 pounds, according to the percentage above you lost 1 pound of fat, 2 pounds of water weight and 2 pounds of lean muscle. Did you want to lose that much muscle? Probably not. All of the diets making you lose more than 1-2 pounds per week will burn your muscle mass for energy.
Now, why is that? The body saves the fat stored in your body for a rainy day (starvation period) and if you are on a diet and don’t exercise and use your muscle to the fullest extent your body figures that the muscle is not necessary to save and it will start using it for energy.
The diet above could be executed once a week but it will not give you a long-lasting weight loss. To lose weight for good you have to compose your menu to have the right amount of protein, the right kinds of fat and some great carbs. Those three nutrients cover our total calorie intake. To be a successful dieter(meaning that the fat is burnt and not the muscle) you should reduce your calorie intake by 10-20% and increase your calorie consumption, and how do you do that? Well, you have to start exercising and do some weight-lifting.
Now you know how to lose weight fast (I guarantee that the menu above works) so stop looking for any more fast weight loss diets. You also know why a fast weight loss is only a temporary weight loss and most important, you know that there are no shortcuts to get rid of those extra pounds. It is really a really easy equation: (Calorie intake) – (Calorie burnt) = weight loss/gain. Simple? Yes! But it is not that easy to achieve because it requires some fundamental change of attitude to foods, exercise and body.
