The metabolic HCG diet is a weight-loss plan involving the use of the hormone HCG (human chorionic gonadotropin) in combination with a very low-calorie diet. HCG is produced in large amounts during the first three months of pregnancy and stimulates the production of other essential pregnancy hormones. The diet was developed by Dr Albert T. W. Simeons in the 1950s and involves three phases: a loading phase, a weight-loss phase, and a maintenance phase. During the loading phase, dieters eat high-calorie, high-fat foods for two days. The weight-loss phase involves eating a very low-calorie diet (500 to 800 calories per day) and taking HCG through an injection, tablet, or other form for three to six weeks. In the maintenance phase, dieters stop taking HCG and gradually increase their food intake while avoiding sugar and starch. While the HCG diet has grown in popularity, it is not approved for weight loss and there is no scientific evidence that it is effective.

HCG diet involves taking the hormone HCG to reduce appetite and cause weight loss
The HCG diet involves taking human chorionic gonadotropin (HCG), a hormone produced in large amounts during the first three months of pregnancy. This diet was developed by Dr Albert T. W. Simeons in the mid-1950s and gained popularity in 2009. It is a very low-calorie diet, with a daily intake of around 500 to 800 calories. Proponents of the diet claim that it boosts metabolism, prevents muscle loss, and reduces appetite, all while helping to lose large amounts of abnormal fat weight.
HCG is typically taken through injections, tablets, or other forms during the weight loss phase, which lasts around three to six weeks. During this phase, individuals are instructed to follow an ultra-low-calorie diet. The HCG diet claims to promote rapid weight loss by resetting the hypothalamus and signalling the body to break down and use abnormal fat as fuel. It is believed that this process helps maintain lean body mass and prevents a decrease in basal metabolic rate, which is common in other low-calorie diets.
However, it is important to note that the FDA advises against using HCG for weight loss, as it is not approved for this purpose. There is a lack of scientific evidence supporting the claims made by proponents of the HCG diet. Multiple studies have found no significant difference in weight loss between individuals taking HCG and those receiving a placebo while on a calorie-restricted diet. Additionally, these studies suggest that the HCG hormone does not effectively reduce hunger or promote weight loss.
The HCG diet can be dangerous and may lead to adverse side effects. Very low-calorie diets can increase the risk of gallstone formation, electrolyte imbalances, and irregular heartbeats. Therefore, it is crucial to consult with a healthcare professional before considering any restrictive diet or weight-loss plan.

HCG is not approved for weight loss and there is no evidence it helps
The hCG diet involves taking human chorionic gonadotropin, a hormone produced by the placenta during pregnancy, alongside a very low-calorie diet. While hCG products are approved by the FDA as a prescription drug for treating female infertility and other medical conditions, they are not approved for weight loss. In fact, the FDA warns against using them for this purpose, and hCG products that are marketed for weight loss are often sold without a prescription, which is illegal.
The prescription drug label for hCG notes that there is "no substantial evidence" that it increases weight loss, influences the distribution of fat, or decreases hunger and discomfort associated with calorie-restricted diets. This lack of evidence is supported by multiple studies that have tested the effectiveness of the hCG diet since it was introduced by British doctor Albert T. W. Simeons in 1954. A 1995 analysis of 24 studies found no evidence that the hCG diet helps reduce hunger, promote weight loss, or trim fat from areas like the hips and thighs. Other research found that placebo injections worked just as well as hCG injections for treating obesity. Due to this lack of evidence, the American Society of Bariatric Physicians recommends against using the hCG diet for weight loss.
The makers of hCG products for weight loss claim that they can boost your metabolism, reduce hunger, and help you lose up to 30 pounds in a month or two. However, these claims are not supported by scientific evidence. The extremely low-calorie diet recommended alongside hCG products (as little as 500 calories per day) is also unhealthy and dangerous. Living on such few calories can lead to nutritional deficiencies, and people on such restrictive diets are at increased risk for side effects, including gallstone formation, an imbalance of electrolytes, and an irregular heartbeat, which can be potentially fatal.
If you have been using hCG products for weight loss, you should stop using them and throw them out. Talk to your healthcare professional about a safe and healthy weight loss plan that takes into account your individual needs and health status.

The diet includes a very low-calorie diet, usually 500 to 800 calories per day
The HCG diet is an extremely low-calorie diet, usually limiting consumption to 500 to 800 calories per day. This is combined with taking HCG, a hormone produced in large amounts during the first three months of pregnancy, through an injection, tablet, or other form. The HCG diet was introduced by British doctor Albert T. W. Simeons in 1954, who claimed that it could promote rapid weight loss, particularly from areas such as the buttocks and thighs, without causing muscle loss.
The diet typically consists of three phases: the loading phase, weight loss phase, and maintenance phase. During the loading phase, which lasts two days, individuals consume high-calorie, high-fat foods to prepare their body for the upcoming calorie restriction. The weight loss phase involves adhering to a very low-calorie diet, typically restricted to 500 calories per day, alongside daily HCG injections. This phase usually lasts between three to six weeks.
In the maintenance phase, individuals stop taking HCG and gradually transition to a well-balanced diet, avoiding sugar and starch for the first three weeks. This phase focuses on maintaining the weight loss achieved during the previous phase and adapting to new eating habits. It is important to note that the HCG diet is controversial, and there is a lack of scientific evidence supporting its effectiveness.
Proponents of the HCG diet claim that it boosts metabolism, reduces hunger, and promotes fat loss without affecting muscle mass. However, multiple studies have found no evidence that the HCG hormone contributes to weight loss, reduction of hunger, or targeted fat loss. Additionally, very low-calorie diets can be dangerous and may lead to side effects such as gallstone formation, electrolyte imbalances, and irregular heartbeats. Therefore, it is crucial to consult a healthcare professional before considering such restrictive diets.

HCG diet is believed to help maintain lean body mass (muscle) and prevent metabolic slowdown
The HCG diet is a weight-loss plan involving the use of the hormone hCG (human chorionic gonadotropin) in combination with a very low-calorie diet. Typically, the diet is divided into three phases: loading, weight loss, and maintenance. During the loading phase, dieters consume high-calorie, high-fat foods for two days. This is followed by the weight loss phase, where dieters restrict their calorie intake to 500-800 calories per day while taking hCG through injections, tablets, or other forms. The final phase involves gradually increasing food intake while avoiding sugar and starch, with the goal of maintaining weight loss.
The HCG diet is believed by some to help maintain lean body mass (muscle) and prevent metabolic slowdown. Proponents of the diet claim that it supports rapid weight loss by targeting cravings, encouraging fat burning, and protecting against muscle loss. However, it's important to note that these claims are not supported by scientific evidence. The FDA has not approved hCG for weight loss and warns against its use due to safety concerns.
The HCG diet has been associated with several side effects, including gastrointestinal issues such as nausea, vomiting, bloating, and indigestion. Additionally, dieters may experience a decrease in urinary frequency, which can lead to urinary tract infections (UTIs) and other complications. One of the most concerning side effects is the potential for fluid buildup (edema), which can be particularly noticeable in the legs, hands, and feet. In rare cases, women taking HCG have developed ovarian hyperstimulation syndrome (OHSS), typically seen during IVF treatment.
Furthermore, very low-calorie diets like the HCG diet can have serious health risks. Restrictive diets can lead to an increased risk of gallstone formation, electrolyte imbalances, and irregular heartbeats. They can also result in a deficiency of essential vitamins, minerals, and protein. As a result, healthcare professionals recommend gradual weight loss and moderate calorie reduction instead of extreme calorie restriction.
While the HCG diet may show short-term weight loss, it is not a sustainable or safe method for long-term weight management. It is always advisable to consult with a healthcare professional before starting any weight-loss plan to ensure it is safe and appropriate for your individual needs.

HCG diet products are available over-the-counter and should be avoided without a prescription
The HCG diet, short for the Human Chorionic Gonadotropin diet, was introduced by British doctor Albert T. W. Simeons in 1954. It involves a very low-calorie diet, restricting calories to 500-800 per day, alongside taking HCG through an injection, tablet, or other form. HCG is a prescription drug approved for treating female infertility and other medical conditions.
Despite its popularity, the FDA has not approved over-the-counter (OTC) HCG products for weight loss. In fact, the FDA warns against using these products or following the HCG diet, stating that there is no evidence that HCG increases weight loss beyond that resulting from caloric restriction. The prescription drug label also notes that there is "no substantial evidence" that HCG causes a more attractive distribution of fat or decreases hunger and discomfort associated with calorie-restricted diets.
Additionally, very low-calorie diets can be dangerous and may lead to serious side effects, including gallstone formation, electrolyte imbalances, and irregular heartbeats. Without medical oversight, individuals on such diets may not be getting adequate vitamins, minerals, and protein.
Therefore, it is essential to avoid OTC HCG products and not follow the HCG diet without a prescription. If you want to lose weight, it is advisable to do so gradually by reducing your daily calorie intake and consulting a healthcare professional for a safe and healthy weight loss plan.
