Another trend, is the diet that is back on the radar and promises to help dieters lose one pound per day, or even more. It is the diet of HCG (Human Chorionic Gonadotropin), and was developed  by a doctor who believes that a hormone found in the body of a pregnant woman can help overweight men and women lose weight, and maintain that weight even after returning to normal routines.
HCG and Pregnancy
In 1927, the researchers discovered that in  the urine of pregnant women was a substance that normally does not occur outside of pregnancy: human chorionic gonadotropin or HCG. This represented the first modern  pregnancy test , and to date, urine is still checked for signs of HCG to determine pregnancy.Doctors also look at HCG levels (among other factors) in pregnant women to assess the risk of birth defects.
HCG can play many roles, but one function it does is to ensure that the developing fetus receives the calories and nutrients it needs to grow, almost independent of the daily caloric intake of the pregnant woman in those early months of development. How to do this?
We are not hungry for high-fat foods for no reason. Our body wants to maximize caloric intake in the case of difficult times. In the case of women, excess calories tend to end in “problems” in areas such as the hips, buttocks, abdomen and thighs. However, once pregnant, the fat from these areas is released in the presence of HCG, and this fat then works its way to the fetus. In this way, if a woman does not consume the nutrients necessary for the growth of the fetus, her fat reserves will suffice. (Structural fat, such as that found on the face or in layers below the entire skin, is not affected.)
HCG is produced by a woman at the beginning of her pregnancy, and HCG levels at peak blood flow in about 14 weeks. After that, the levels gradually decrease. HCG and its presence in a pregnant woman seems to occur in the period in which a woman would be less likely to know that she is pregnant, and therefore, it is likely (especially in the ancient times of human history) to be consciously trying of ensuring nutrients to maintain a pregnancy.
On the other hand, HCG (Human Chorionic Gonadotropin) was used as a treatment for children suffering from a delay in adolescence or genital development due to disorders of the pituitary gland.
It was during research in the 1930s, when a physician, ATW Simeons, realized that children treated with HCG for underdeveloped gonads were also able to lose excess weight by eating much less without the feeling of hunger that accompanied them. . Simeons’ interest in HCG soon changed its potential as a dietary aid, and after two decades of research, published an article promoting its effects, and has developed a dietary regime for the use of the drug as a tool to lower of weight.
Weight Loss with the HCG Method and Calorie Burning
 Despite subsequent HCG diets, most programs remain very faithful to the original formed by Dr. Simeons.
Each round of treatment lasts a minimum of 26 days, and 23 of these days require a daily dose of HCG, either through injections or drops under the tongue. The treatment can last up to 43 days (with 40 injections), unless a patient loses 34 to 40 pounds (15 to 18 kilograms) before the expected time. Patients who do not receive HCG injections during the last three days of a treatment period, so that the hormone can complete a full cycle in their bodies before resuming a normal diet.
Why stop after 40 days? Simeons observed that the subjects seemed to develop immunity to HCG after 40 days and needed a six-week break from the diet. Simeons recommends no more than four treatments in total, separated by breaks.
In addition to receiving the hormone, dieters are instructed to reduce their daily caloric intake by about 500 a day, but not until after the third dose. Once HCG is active in a dieter’s body, the release of stored fat provides the body with the calories it needs to burn in a day (one day, it should be noted, without much exercise). While the fat deposits are being released for use, of the 500 daily calories that are ingested it is supposed to be sufficient to maintain the diet without the feeling of hunger. Once a dieter decreases excess weight, treatment should be stopped, since HCG only affects stored fat. Once used, the body quickly rejects a self-imposed limit of 500 total daily calories.
Of the few foods that you can eat on the HCG diet, it is supposed to be high in protein and low in starch, carbohydrates and high-fat foods. Dairy products, sugar and alcohol are prohibited, you must spend the next 24 hours drinking water and eating six apples.
The Dangers of the HCG Diet
Losing weight at a rate of one pound a day may sound tempting, but the HCG diet may present some very serious health risk.
Taking the HCG hormone itself can cause a variety of complications that can be read as the fine print on the prescription of a disclaimer: Users can report cases of headaches, blood clots, agitation, cramps in the legs, constipation, temporary thinning, depression and enlarged male breasts. Also, can you feel, like, pregnant, swelling, breast tenderness and water retention, anyone? HCG can also cause a life-threatening condition called ovarian hyperstimulation syndrome (OHSS), in which ovaries over-stimulated by hormones can swell and leak fluid in the abdomen. This can cause abdominal pain and weight gain,
On top of the possible complications of the hormone, low-calorie diets that have their own set of side effects were strongly reduced. While the amount of calories your body needs depends on the amount of activity we do every day, more adult women need between 1,800 and 2,400 calories per day, and adult men need between 2,000 and 3,000 calories per day. Those who try to lose weight usually eat between 1,200 and 1,500 calories per day. At 500 calories, the HCG diet requires only a fraction of those requirements.
When you are on a very low calorie diet like the HCG plan. By allowing yourself so few calories per day, it can be difficult to meet your daily nutritional needs. You may also experience some not-so-pleasant side effects such as fatigue, nausea, constipation and diarrhea. Your hair may start to fall. Worse, you can develop gallstones, which may require surgery to correct.
The FDA has also received at least one report of an HCG diet, which developed a pulmonary embolism, a blood clot in the lung that can be potentially fatal.
Proponents of the feeding point indicate that the HCG hormone is natural and clear, is safe for pregnant women and fetuses that lead to dieters, and that they receive a much lower dose of HCG that is found in normal conditions in women pregnant.
