The hCG diet has remained popular for years. Although hCG is not intended for weight loss and the Food and Drug Administration (FDA) has called the diet dangerous, hCG diet reviews from those who have used it are largely positive. The reason the FDA warns against the diet is that it is extreme. The diet claims to provide up to a pound or two of weight loss per day.

The hCG diet is a very low-calorie diet, which restricts food intake to 500 calories per day but promises that you won’t feel hungry while you are on the diet. Reading hCG diet reviews and comparing it to other diets can help you find the best method for you to reach your weight loss goals.

What Are HCG Diet Reviews?

Human chorionic gonadotropin (hCG) is the hormone that is present in the body during pregnancy and detected by home pregnancy tests. The hormone is also used for infertility in men and women. An off-label use of the hormone is weight loss, but it is not approved by the FDA for this purpose. The diet was developed in 1954 by a British physician named Albert Simeons, and hCG diet reviews have been largely positive from that time until now.

Dr. Simeons developed the diet with two components: a diet of only 500 calories per day and daily hormone injections of hCG. You can learn about the effectiveness and results others have gotten from this diet by reading hCG diet reviews and comparing the results with other diet plans.

How Does the HGC Diet Work?

Advocates of the hCG diet assert that the diet is effective for boosting the metabolism and curbing hunger, so you lose weight and burn fat without feeling hungry. There are several theories that explain the weight loss mechanism of this hormone. Detractors of the diet insist that the weight loss benefits gained from the diet are solely caused by the very low-calorie diet and not from the hormone.

One major problem with diets, in general, is that there is often a loss of muscle mass, as well as fat loss. When calories are severely restricted, this becomes an even greater concern. However, the use of hCG promotes fat loss and limits muscle loss. The hormone elevates other hormones in the body and boosts metabolism. This leads to an anabolic state, or muscle building state, which helps you burn fat without losing muscle mass.

Three Phases of the hCG Diet

Phase one of the hCG diet is known as the “loading phase” and during this phase, you do not have to restrict calories or the foods that you enjoy. The loading phase lasts for the first two days of the diet. During this time, you are encouraged to eat plenty of high fat and high-calorie foods. Enjoy all your favorite foods and do not limit the quantity of the food you are eating. You will begin taking hCG on the first day of the diet and continue throughout the first two phases.

Phase two is known as the weight loss phase of the diet. This lasts from three to six weeks, depending on the amount of weight an individual has to lose. During this phase, you will continue to take the hCG and consume a diet of only 500 calories per day. There are many food restrictions during this phase of the diet.

Phase three is the maintenance phase. You will stop using hCG and increase your food intake gradually. You should avoid sugar and starch for the first three weeks of the maintenance phase and then you may have sugar or starch in small amounts. It is important to note that you may regain the weight you lost if you go back to a high-fat, high-calorie diet after the maintenance phase. Stick to healthy food choices to maintain your weight loss.

Foods on the hCG Diet

When you are in the weight loss phase of the diet, you are only allowed 500 calories per day. This is usually limited to only two meals, lunch, and dinner. However, if you have blood sugar issues, you may need to have a small snack in the morning. If you have a health condition, you should talk to your doctor before trying any weight loss method to make sure it is safe for you.

There are several food restrictions on this diet. You cannot have sugar, butter, or oils of any kind. During each of the two meals, you are directed to include one protein, one vegetable, one bread, and one fruit. However, there are many restrictions on the foods that are allowed.

The meats that are allowed are broiled or grilled chicken breast, beef, veal, fresh white fish, crab, shrimp, or lobster. There should be no visible fat on the meat. Vegetables include spinach, beet greens, tomatoes, green salad, celery, cucumbers, chard, onions, asparagus, fennel, and cabbage. Fruits that are allowed on the diet include an apple, orange, half a grapefruit, or a handful of strawberries. Bread can be either a breadstick or melba toast. Drinks are limited to water or coffee or tea without sugar.

Choosing Quality hCG

One reason that hCG diet reviews are mixed may be attributed to the quality of the hCG that people are using. The original diet calls for the use of hCG injections, which contain the hormone human chorionic gonadotropin. There are also diet drops that contain true hCG. However, there are a variety of products on the market now, including drops, sprays, and pellets.

It is important to note that not all of these products actually contain hCG in amounts that are sufficient for curbing hunger on the diet. Some products sold in stores are homeopathic drops, sprays, or pellets. These may contain little, if any, hCG. If you are feeling starved on the diet, make sure you are actually taking authentic hCG, since the homeopathic products may not contain enough of the hormone to produce the desired results.


The cost of the diet is the cost of your food and the hCG injections, which can vary in price depending on how long you are on the weight loss phase. For example, if you are on it for six weeks, the injections will cost twice as much as if you only stayed on it for three weeks. Various hCG diet reviews mention the cost of the hormone as between $ and $$ per injection.

This is the most common way that intermittent fasting is used.
