The HCG diet is a weight-loss plan that involves taking supplements of the hormone human chorionic gonadotropin (HCG) while consuming only 500 to 800 calories per day. The diet has been around since the 1950s, but it surged in popularity in 2009 due to renewed attention on the internet. While proponents of the diet claim that it boosts metabolism and causes rapid weight loss, there is no scientific evidence to support these claims. In fact, multiple studies have found that any weight loss achieved on the HCG diet is due to the severe calorie restriction alone, and not the HCG hormone. The HCG diet is not approved by the FDA for weight loss, and there are concerns about its safety due to the risk of nutrient deficiencies and side effects such as gallstones, irregular heartbeat, and low electrolytes.

What You'll Learn
The hCG diet is not approved by the FDA
The hCG diet involves taking human chorionic gonadotropin, a hormone produced by the placenta during pregnancy, and following a very low-calorie diet. Typically, this means restricting calorie intake to 500 per day, although some versions of the diet allow up to 800 calories. The diet was introduced by British doctor Albert T. W. Simeons in a 1954 medical journal article. He claimed that hCG injections could promote fat loss in specific areas of the body, such as the belly, hips, buttocks, and thighs.
However, the hCG diet is not approved by the FDA. The FDA has approved hCG as a prescription drug for the treatment of female infertility and other medical conditions, but it is not approved for weight loss without a prescription. The prescription drug label notes that there is "no substantial evidence" that hCG increases weight loss beyond that resulting from caloric restriction or that it causes a more "normal" distribution of fat.
In addition, the FDA warns that very low-calorie diets, such as the hCG diet, can be dangerous. Restricting calories to 500 per day can lead to nutritional deficiencies, and may cause side effects such as gallstone formation, an imbalance of electrolytes, and an irregular heartbeat. These diets can even be potentially fatal. The American Society of Bariatric Physicians also recommends against using the hCG diet for weight loss due to the lack of evidence supporting its effectiveness.
If you want to lose weight, it is important to do so gradually and safely. It is recommended to speak to a healthcare professional about a healthy weight loss plan that takes into account your individual needs and health status.

The diet involves severe calorie restriction
The HCG diet is a weight-loss plan that involves taking human chorionic gonadotropin (HCG), a hormone produced by the placenta during pregnancy, in combination with a very low-calorie diet. Typically, the diet restricts daily calorie intake to between 500 and 800, with some sources specifying a limit of just 500 calories. This severe calorie restriction is a key component of the diet and is intended to promote rapid weight loss.
The HCG diet is usually divided into three phases: the loading phase, the weight loss phase, and the maintenance phase. During the loading phase, there are no restrictions on food intake, and dieters are encouraged to eat high-calorie, high-fat foods to boost their metabolism before beginning the weight loss phase. The weight loss phase is when the severe calorie restriction takes place, with dieters limited to just 500-800 calories per day, spread across two meals. This phase typically lasts for three to six weeks, but this can be extended for those seeking significant weight loss.
The maintenance phase involves stopping the HCG treatment and adopting a well-balanced diet and exercise routine, with the goal of maintaining long-term weight loss. While the HCG diet allows for a variety of foods, including fruits and vegetables, the severe calorie restriction may make it challenging for those with specific dietary requirements, such as vegetarians and vegans, to obtain adequate nutrition. For example, during the weight loss phase, some animal-based protein sources are recommended, which may be difficult for those following a plant-based diet.
The HCG diet has been controversial due to the severe calorie restriction it entails. Such restrictive diets can lead to unpleasant side effects, including headaches, brain fog, fatigue, and dizziness, as well as gallstones, irregular heartbeat, and low electrolytes. Consuming fewer than 1,200 calories per day makes it difficult to meet nutritional requirements, and can result in vitamin and mineral deficiencies. Therefore, it is recommended that very low-calorie diets are only undertaken with careful supervision by a healthcare professional.

There is no scientific evidence that it works
The hCG diet, also known as the Human Chorionic Gonadotropin diet, involves taking a hormone produced by the placenta during pregnancy and following a very low-calorie diet. This hormone is typically injected, but it can also be taken in tablet or drop form. The diet usually restricts calorie intake to 500 to 800 calories per day, and it is often marketed with claims that it can "reset your metabolism" and change "abnormal eating patterns".
However, there is no scientific evidence that the hCG diet works. A 1995 analysis of 24 studies found no evidence that this diet helps reduce hunger, promote weight loss, or trim fat from specific areas of the body. Other research found that placebos or fake injections worked just as well as hCG injections for treating obesity. The American Society of Bariatric Physicians recommends against using the hCG diet for weight loss due to the lack of evidence supporting its effectiveness.
Additionally, the hCG diet can be dangerous. The FDA warns against using hCG products for weight loss, as they are not approved for this purpose and can cause harmful side effects. The prescription drug label for hCG notes that there is "no substantial evidence that it increases weight loss beyond that resulting from caloric restriction". Very low-calorie diets can lead to vitamin and mineral deficiencies and increase the risk of side effects such as gallstones, irregular heartbeat, and low electrolytes.
Furthermore, the hCG diet may be difficult to follow due to the strict calorie restrictions. It can be uncomfortable and challenging to limit calorie intake to just 500 calories per day, and it may be impossible to meet all nutritional needs on such a restricted diet. As a result, people on very low-calorie diets without medical supervision are at risk of experiencing life-threatening side effects.
In conclusion, there is no scientific evidence that the hCG diet works, and it may pose serious health risks. It is important to consult a doctor before starting any new diet plan to ensure it is safe and appropriate for your individual needs.

It has been linked to several health risks
The HCG diet has been linked to several health risks. HCG, or human chorionic gonadotropin, is a hormone produced in large quantities by the placenta during pregnancy. The diet involves taking this hormone as a supplement and following a very low-calorie diet, usually restricted to 500 calories per day.
The FDA warns against using HCG products for weight loss, as they are not approved for this use and there is no scientific evidence that they are effective. The prescription drug label notes that there is "no substantial evidence" that HCG increases weight loss beyond that resulting from caloric restriction or that it causes a more "normal" distribution of fat. Additionally, the American Society of Bariatric Physicians recommends against using the HCG diet for weight loss due to the lack of evidence supporting its effectiveness.
The severe calorie restriction recommended in the HCG diet can lead to dangerous side effects, including gallstones, an irregular heartbeat, and low electrolytes. Consuming less than 1200 calories per day makes it difficult to obtain enough vitamins and minerals without supplements. This can result in vitamin and mineral deficiencies, which can have serious health consequences. Very low-calorie diets can be potentially fatal and are only sometimes prescribed by healthcare professionals for individuals who are moderately to extremely obese to reduce obesity-related health risks.
HCG supplementation can also cause various side effects, including allergic reactions, mood changes, facial hair growth, and swelling of the breasts or penis. Nausea, vomiting, and upset stomach are also linked to this hormone. The sudden influx of hormones can cause skin and hair changes, such as acne, as well as changes in mental health, leading to issues like irritability, fatigue, restlessness, and depression.

The diet has been around since the 1950s
The HCG diet has been around since the 1950s. It was introduced by British endocrinologist Albert T. W. Simeons, who published a book about the diet in 1971, titled "Pounds & Inches: A New Approach to Obesity". The book was based on Simeons's observations of pregnant women in India on a calorie-deficient diet and obese boys with pituitary issues (Frölich's syndrome) treated with low-dose HCG. He noticed that both groups lost fat rather than lean tissue, and he attributed this to the effects of HCG on the hypothalamus.
The HCG diet involves taking human chorionic gonadotropin (HCG), a hormone produced during pregnancy, in conjunction with adhering to a very low-calorie diet. Typically, this involves consuming between 500 and 800 calories per day and incorporating daily HCG injections to promote fat loss. The diet has been controversial due to the lack of scientific data supporting its effectiveness and the potential health risks associated with such a restrictive calorie intake.
The Food and Drug Administration (FDA) has not approved HCG for weight loss and has warned against using it for this purpose. The American Society of Bariatric Physicians also recommends against using the HCG diet for weight loss due to the lack of evidence supporting its effectiveness. In addition, the FDA has prohibited the sale of over-the-counter HCG diet products, and there are concerns about the ingredients and safety of "homeopathic HCG" products promoted online.
Despite the controversy and lack of scientific evidence, the HCG diet has surged in popularity multiple times since its introduction, with people seeking quick-fix solutions for weight loss.
