hCG is extremely safe. It is naturally produced by the human body. hCG has been used by doctors in weight loss programs for over 50 years. There are no known side effects associated with the hCG diet.
hCG drops are just as effective as injections. The only difference is that the injections are much more expensive, costing around $700. The most important thing is that people taking drops instead of injections show the same results (losing 1-2 pounds per day).
As a result of being on the diet your eating behavior will change, cravings will disappear, your appetite will decrease, and your body will also change. It is important to understand that the hCG diet is not only a catalyst for weight loss, but also lifestyle change. As with any diet, if you go back to your "old ways" you will gain weight.
After the diet, your hypothalamus has been "reset" which causes your metabolism to change. You will find it easier to eat less, with no real urge or desire to overeat. Developing a moderate exercise regiment of 15-30 minutes a day will also help you keep the fat from coming back. About 80% of people who have done this diet have had no problem in maintaining their "ideal weight".
In the first few days you may feel a little hungry. This feeling should completely go away by week 2 on the diet. Your body will be using a lot more calories from the excess stored fat that the hCG is helping to burn. You will see that it takes a lot less food to feel satisfied. The hypothalamus begins to adjust your metabolic rate, and 500 calories will seem to be more than enough.
While 500 calories per day may seem like a small amount, keep in mind what is happening on the hCG diet. Your hypothalamus is mobilizing your excess stored fat and releasing it to be used. Your body is actually getting thousands (1500 to 4000) of calories per day from this stored fat. Burning all these extra calories from stored fat enables the dieter to lose massive amounts of fat, 1-2 pounds or more, per day.
How will I have energy only eating 500 calories per day?
Many people actually report feeling an increase in energy on this diet. As hCG releases 1500 to 4000 calories from fat stores, along with the extra 500 calories you take in per day, your body will have plenty of energy. After all, "energy" contributed to your body from any food source is measured in, yep, calories.
Wouldn't anyone lose 1-2 pounds/day if they were only eating 500 calories per day?
It is always possible to lose weight by lowering your caloric intake. However, attempting to lose weight by severely limiting your caloric intake without a fat mobilizer such as hCG, would cause other issues. You would be sending your body into starvation mode, sending your metabolism signals to hold on to as much fat as possible. So when you eventually go back to eating more, you could experience accelerated weight gain. In starvation mode, the body also tends to break down muscle before it breaks down stored fat because muscle takes more energy to support.
On the hCG diet you will be using an extra 1500 to 4000 calories from mobilized, stored fat. This prevents your body from going into starvation mode.
