The HCG diet is a short-term eating plan that involves a drastic reduction in calorie intake and the use of the HCG hormone to promote rapid weight loss. The diet is typically divided into three phases: the loading phase, the weight loss phase, and the maintenance phase. During the weight loss phase, dieters are restricted to a very low-calorie intake, often limited to 500 calories per day. To prevent the body from burning carbohydrates for energy, the HCG diet recommends minimizing carbohydrate consumption. This forces the body to tap into its fat stores for fuel, leading to weight loss. While the HCG diet promises dramatic results, health experts warn that it is unsafe, unhealthy, and unsustainable.

What You'll Learn
Carbohydrates are converted into glycogen and stored in the liver
The HCG diet is a short-term eating plan that involves a drastic reduction in calorie intake and the use of HCG hormone supplements or injections. HCG stands for human chorionic gonadotropin, which is a hormone produced during pregnancy. The diet has been deemed unsafe and illegal by the FDA due to its extreme nature and lack of evidence supporting its effectiveness.
Carbohydrates are one of the main sources of glucose, which is a vital source of energy for the body and its organs, muscles, and nervous system. Glucose is especially important for the brain, which consumes approximately 60% of blood glucose in fasted, sedentary individuals. When the body has an excess of glucose, it is stored as glycogen in the liver and muscles. This stored glycogen can then be converted back into glucose when the body needs energy, such as during fasting or exercise.
The liver plays a crucial role in regulating blood glucose levels. Liver glycogen content decreases rapidly during fasting, and after 12-24 hours, it is almost completely depleted. This is because the liver releases glycogen to convert into glucose, which enters the bloodstream and is used by the body for energy. This process is called glycogenolysis and is triggered by the hormone glucagon.
While the HCG diet does not specifically prohibit carbohydrates, it does involve a very low-calorie diet, typically restricting intake to 500-800 calories per day. This extreme calorie restriction is intended to force the body to burn stored fat for energy instead of glucose. As such, dieters are instructed to choose low-calorie foods that are also filling, such as lean proteins. During the weight loss phase, dieters are advised to keep empty carbohydrate intake to a minimum.
In summary, while the HCG diet does not explicitly eliminate carbohydrates, the focus on severe calorie restriction likely results in a reduction in carbohydrate consumption. This, in turn, can affect the body's ability to maintain glycogen stores in the liver and muscles, potentially impacting energy levels and overall health.

The body burns fat when it runs out of carbohydrates
The HCG diet is a short-term eating plan that involves a drastic reduction in calorie intake and the use of the HCG hormone, which stands for human chorionic gonadotropin. This hormone is produced during pregnancy by the placenta, but the diet itself has nothing to do with pregnancy. The diet is typically divided into three phases: the loading phase, the weight loss phase, and the maintenance phase.
During the loading phase, which lasts for two days, individuals eat a high-calorie, high-fat, and high-carb diet. The idea is to store these calories in the form of fat, which the body will then tap into during the second phase. The weight loss phase, which can last between three to six weeks, involves a significant restriction in calorie intake, with individuals consuming only 500 calories per day. During this phase, it is recommended to eat low-calorie foods that are also filling, such as lean proteins and low-carb fruits and vegetables. The goal is to keep the body burning fat for fuel instead of carbohydrates.
The HCG hormone is believed by some to elevate other hormones, boost metabolism, and lead to a growth-promoting, or anabolic, state. However, there is no scientific evidence to support these claims. In fact, multiple studies have concluded that weight loss achieved through the HCG diet is due to ultra-low-calorie intake alone, rather than the HCG hormone. The drastic reduction in calorie intake forces the body to retrieve stored fat when it runs out of readily available sugars. This is why it is important to limit carbohydrate intake during the HCG diet, as carbohydrates are the body's primary source of energy. When carbohydrates are not available, the body turns to fat stores for energy.
During the maintenance phase, individuals gradually discontinue the use of the HCG hormone while slowly increasing their calorie intake. This phase helps to keep the weight off and avoid rebounding to the pre-diet weight. It is important to note that the HCG diet is controversial and not recognized by health experts as safe. The HCG supplements are considered unsafe and illegal in the United States. Therefore, it is recommended to consult with a healthcare provider or registered dietitian before starting this or any other diet plan.

The HCG diet is extremely low-calorie
The HCG diet is a short-term eating plan that involves a drastic reduction in calorie intake, typically to between 500 and 800 calories per day. This extreme calorie restriction is one of the main reasons why the diet promises rapid weight loss in a short amount of time.
During the weight loss phase, adherents of the HCG diet typically consume a very low-calorie diet while taking HCG supplements or injections. The idea is that the body will be forced to retrieve stored fat for energy when it runs out of its usual supply of sugars from carbohydrates. By limiting carbohydrates, the body is encouraged to burn fat for fuel instead.
The HCG diet is often divided into three phases: the loading phase, the weight loss phase, and the maintenance phase. The loading phase typically lasts for two days, during which individuals eat a high-calorie, high-fat diet to prepare the body for the low-calorie phase. The weight loss phase then involves a significant reduction in calorie intake, typically to around 500 calories per day. This phase can last anywhere from three to six weeks, depending on individual weight loss goals.
During the weight loss phase, dieters are encouraged to choose low-calorie foods that are also filling, such as lean proteins like white fish, lean beef, egg whites, or crab. Carbohydrate intake is limited, with a focus on low-carb fruits and vegetables like apples, asparagus, broccoli, spinach, and kale. It is important to note that the HCG diet is not recognized by health experts as safe, and there is no scientific evidence that it is effective for long-term weight loss.

The body can enter 'starvation mode' and burn muscle tissue
The HCG diet is a short-term eating plan that involves a drastic reduction in calorie intake and the use of the HCG hormone, which stands for human chorionic gonadotropin. This hormone is produced during pregnancy and is believed to drive the body to burn fat. The diet typically lasts between three and six weeks and promises dramatic weight loss.
However, health experts warn against the HCG diet, stating that it is extreme, unsustainable, and illegal. The extreme calorie restriction can lead to various side effects, including decreased muscle mass. When the body experiences a severe reduction in calories, it may enter a state known as "starvation mode." This occurs when the body has no more fuel to burn and starts breaking down muscle tissue for energy.
During the weight loss phase of the HCG diet, individuals are restricted to a very low-calorie intake, typically limited to 500 or 800 calories per day. This drastic reduction in calories can deplete the body's primary fuel sources, stored sugar (glycogen) and stored fat. When these sources are depleted, the body may start breaking down muscle tissue to meet its energy demands.
To prevent muscle loss during the HCG diet, adequate protein intake is crucial. Protein helps keep individuals satiated and makes sticking to the diet easier. Additionally, physical activity is recommended during the HCG diet. It helps burn fat faster and promotes heart health. However, it is important to note that weight training may be necessary to maintain lean muscle mass while losing weight.
While the HCG diet claims to cause only fat loss and prevent muscle loss, there is no scientific evidence to support these claims. Low-calorie diets, like the HCG diet, are associated with decreased muscle mass due to the body's response to extreme calorie restriction. Therefore, it is essential to carefully consider the potential risks and side effects before embarking on the HCG diet or any other extreme diet plan.

The diet is not recognised as safe by health experts
The HCG diet is a short-term eating plan that involves a drastic reduction in calorie intake, alongside daily HCG hormone supplements or injections. The HCG hormone, or human chorionic gonadotropin, is produced by the placenta during pregnancy. The diet has two main phases: the loading phase and the weight loss phase. During the loading phase, which lasts for two days, people are encouraged to eat extremely high-fat, high-calorie foods, consuming up to 2,250 calories a day from fat alone. The idea is that this will stock the body's normal fat cells, preparing the body to burn "abnormal" fat during the weight loss phase.
During the weight loss phase, people continue taking HCG supplements while restricting their daily caloric intake to between 500 and 800 calories, spread over two meals. This phase typically lasts between three to six weeks. While the HCG diet promises dramatic weight loss in a short amount of time, it is not recognised by health experts as a safe practice.
The U.S. Food and Drug Administration (FDA) has warned consumers that over-the-counter HCG products are illegal and unsafe. The FDA has only approved HCG as a prescription medicine for certain medical conditions, such as female infertility, and it is not approved for weight loss. The prescription drug label notes that there is "no substantial evidence" that HCG increases weight loss beyond that resulting from caloric restriction.
The HCG diet is considered highly unsafe and unhealthy due to the extreme calorie restriction it entails. Such restrictive diets can be dangerous and may lead to serious side effects, including gallstone formation, electrolyte imbalances, and irregular heartbeats. Without medical oversight, people on very low-calorie diets may also suffer from nutritional deficiencies, lacking sufficient vitamins, minerals, and protein.
The most common side effects of the HCG diet include depression, extreme fatigue, swelling or edema, enlarged breasts in men, and trouble sleeping. Rarer but more severe side effects include blood clots, testicle tumours, and ovarian cysts. Given these risks, health experts strongly discourage individuals from attempting the HCG diet and recommend safer alternatives for weight loss.

Frequently asked questions
The HCG diet is based on the idea of altering the body's hormones to turn fat into fuel. The body has two fuel sources for daily metabolic functions: "sugar" (carbohydrates) and stored fat. By reducing the intake of carbohydrates, the body is forced to burn fat for fuel.
The HCG diet is a short-term eating plan that takes between three and six weeks to complete. It involves taking hormone supplements or injections alongside an extremely low-calorie diet.
The main phases of the HCG diet are the loading phase, the weight loss phase, and the maintenance phase. During the loading phase, people preparing to begin the diet eat extremely high-fat, high-calorie foods for two days. The weight loss phase involves consuming either 500 or 800 calories per day, with a focus on low-calorie, filling foods and low-carb fruits and vegetables. The maintenance phase involves a gradual discontinuation of HCG supplementation while slowly increasing calories.
The HCG diet is not recognized by health experts as safe. The FDA has warned about the safety and fraudulent weight-loss claims of HCG supplements, which are illegal in the United States. Multiple studies have concluded that weight loss achieved by the HCG diet is due to ultra-low-calorie intake alone, rather than the HCG hormone.
