The HCG diet is a weight-loss plan that involves taking daily injections of human chorionic gonadotropin (HCG) alongside a severe calorie restriction of only 500 calories per day. HCG products are sold in various forms, including oral drops, pellets, and sprays, and are often marketed with promises of rapid weight loss. However, it's important to note that the FDA has not approved HCG for weight loss, and there is limited evidence supporting its effectiveness. The extreme calorie restriction recommended in the HCG diet can be dangerous and may lead to side effects, including gallstone formation and irregular heartbeat.

What You'll Learn

HCG diet drops are not approved for weight loss
The HCG diet involves taking human chorionic gonadotropin, a hormone produced by the placenta during pregnancy, in combination with a very low-calorie diet. Typically, this means restricting calorie intake to 500 per day, although some diets allow for 800 calories. The HCG is usually administered via injections, but it can also be taken orally in the form of diet drops, pellets, or sprays.
In fact, the FDA warns consumers to avoid HCG weight-loss products, stating that very restrictive diets, such as the HCG diet, are dangerous. Living on a very low number of calories can be unhealthy and may lead to serious side effects, including gallstone formation, an imbalance of electrolytes, and an irregular heartbeat. These diets can be potentially fatal and should only be undertaken with strict and constant medical supervision.
Despite the claims of HCG diet proponents, multiple studies have found no evidence that the HCG diet helps reduce hunger, promote weight loss, or trim fat from specific areas of the body. A 1995 analysis of 24 studies concluded that any weight loss resulting from the HCG diet is entirely due to the low-calorie component of the diet, not the HCG itself. Due to the lack of evidence supporting its effectiveness and the potential risks associated with very low-calorie diets, the American Society of Bariatric Physicians recommends against using the HCG diet for weight loss.

HCG is a hormone produced during pregnancy
Human chorionic gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. It is sometimes referred to as the "pregnancy hormone" because of its unique role in supporting pregnancy. HCG can be found in the blood and urine around 10 to 15 days after conception, with levels rising rapidly and steadily in the first trimester before declining.
HCG plays a crucial role in the early stages of pregnancy by helping to thicken the uterine lining to support a growing embryo and signalling the body to stop menstruation. The rapid increase in HCG levels during the first trimester may also contribute to the nausea and vomiting often associated with pregnancy.
The presence of HCG in the body is detected by pregnancy tests, which can be done at home or by a healthcare provider. These tests can be qualitative, determining the presence of HCG, or quantitative, measuring the amount of HCG present. Obstetricians typically check HCG levels early in pregnancy and may re-check them if there are signs of problems or concerns about the progress of the pregnancy.
While HCG is essential for supporting a healthy pregnancy, it has also been the subject of controversy due to its association with weight-loss products. The HCG diet involves combining daily injections of HCG with a severe calorie restriction of only 500 calories per day. However, it is important to note that the FDA has not approved HCG for weight loss, and there is no scientific evidence that it causes weight loss, redistributes fat, or reduces hunger. In fact, the FDA advises consumers to avoid HCG weight-loss products as they are potentially dangerous and can lead to side effects such as gallstone formation, electrolyte imbalances, and irregular heartbeats.

HCG diet side effects include gallstones and irregular heartbeat
The HCG diet involves taking a hormone called human chorionic gonadotropin, which is produced by the body during pregnancy, and following a very low-calorie diet. The diet usually restricts calorie intake to 500 per day, although some variations allow for up to 800 calories. It is often sold in the form of oral drops, pellets, and sprays, and can be found online, at weight loss clinics, and in some retail stores.
HCG is not approved by the FDA for weight loss and there is no scientific evidence that it aids weight loss. In fact, the FDA warns against using HCG products for weight loss, stating that they are not safe and that any weight loss is due to the low-calorie diet. The prescription drug label on HCG notes that there is "no substantial evidence that it increases weight loss beyond that resulting from caloric restriction".
Despite its popularity, the HCG diet has been associated with several side effects, including gallstones and irregular heartbeat. Gallstones can form as a result of the very low-calorie diet, which can also cause an imbalance of electrolytes, leading to an irregular heartbeat. Other side effects of the HCG diet include 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.
Due to the potential dangers of the HCG diet, it is important to consult a doctor before starting this or any other new diet plan. There are safer ways to lose weight that do not involve supplements or highly restrictive diets. A balanced diet and regular exercise are recommended by healthcare professionals as a healthier and more effective way to lose weight and maintain long-term weight loss.

HCG diet drops are available online and in retail stores
HCG diet drops are often marketed as a weight-loss aid, claiming to boost metabolism, reduce hunger, and promote rapid weight loss when paired with a very low-calorie diet. However, health professionals advise that such restrictive diets can be dangerous and may lead to serious side effects, including gallstone formation, electrolyte imbalances, and irregular heartbeats.
The HCG diet, introduced by British doctor Albert T. W. Simeons in 1954, involves consuming only 500 to 800 calories per day and taking HCG through injections, tablets, or drops. While this diet has surged in popularity, a 1995 analysis of 24 studies found no evidence that it helps reduce hunger, promote weight loss, or trim fat from specific areas of the body.
Despite the availability of HCG diet drops online and in stores, it is essential to prioritize health and safety when considering weight loss methods. Consulting with a healthcare professional is crucial to ensure that any weight loss plan is safe, effective, and tailored to individual needs.

The HCG diet includes a very low-calorie diet
The HCG diet is a weight-loss plan that combines daily injections of human chorionic gonadotropin (HCG) with a severe calorie restriction of only 500 calories per day. The HCG diet plan recommends eating either 500 or 800 calories spread over two meals per day. The timing of these meals is not critical, but in general, calories are divided equally between lunch and dinner. This diet plan allows for one tablespoon of milk per day, and some people choose to put it in their coffee at breakfast.
The HCG diet plan does not require specific recipes, but many online resources offer suggestions for meal plans that stay within the 500-calorie-per-day target. While you can eat a variety of foods on this diet, the calorie count is so restrictive that it might be hard for people with specific diets to follow. For example, during the weight loss phase, you will need to eat some protein from animal sources, such as chicken, beef, fish, and eggs, which could be a problem for vegetarians and vegans.
The HCG diet is controversial because it combines illegal HCG supplements or hormone injections with an extremely low-calorie diet. HCG supplements are not approved for weight loss and there is no scientific evidence that they help with weight loss. In fact, the prescription drug label for HCG notes that there is "no substantial evidence that it increases weight loss beyond that resulting from caloric restriction". Additionally, the U.S. Food and Drug Administration (FDA) has only approved prescriptions for HCG drugs for the treatment of female infertility, and no HCG supplements may be legally sold in the United States for weight loss.
The FDA warns that very restrictive diets, such as the HCG diet, are dangerous. Living on 500 calories a day is not only unhealthy but also dangerous, and people on such restrictive diets are at increased risk for side effects, including gallstone formation, an imbalance of electrolytes, and an irregular heartbeat. Without medical oversight, people on very low-calorie diets may not be getting enough vitamins, minerals, and protein.
