The quest for effective weight loss solutions has led to various trends and methods, with HCG (Human Chorionic Gonadotropin) weight loss shots being one of the more controversial. This article delves into the details of HCG, its purported role in weight loss, the science (or lack thereof) behind the claims, potential risks, and the stance of various health organizations.
What is HCG?
Human Chorionic Gonadotropin (HCG) is a hormone naturally produced in the human body. In women, HCG supports the normal development of an egg in the ovary and stimulates its release during ovulation. It is also used to treat infertility in women and to increase sperm count in men. Additionally, HCG may be used in young boys when their testicles have not descended normally into the scrotum, a condition sometimes caused by a pituitary gland disorder. During pregnancy, the placenta produces HCG in large amounts, which is why pregnancy tests measure HCG levels.
HCG and Weight Loss: Separating Fact from Fiction
The central claim surrounding HCG weight loss shots is that they can help individuals lose weight quickly and efficiently by targeting fat stores, reducing hunger, and boosting metabolism. However, scientific evidence and the consensus of medical experts paint a different picture.
The Core Issue: Calorie Restriction, Not HCG
The fundamental principle to understand is that HCG itself does not result in weight loss. Any weight loss observed in individuals using HCG is primarily attributed to the very-low-calorie diet (VLCD) they are prescribed to follow.
Many HCG protocols involve consuming as little as 500 calories per day. This drastic calorie restriction inevitably leads to weight loss, regardless of whether HCG is administered or not. The methods used alongside HCG, such as a very-low-calorie-diet (VLCD), are what might result in weight loss. HCG providers often prescribe a 500-calorie diet. However, there are risks associated with a VLCD, and medical monitoring is suggested as a standard of medical care. It's actually the diet that accompanies "prescriptions" of HCG that causes the weight loss.

Why the Perceived Lack of Hunger?
One common claim associated with HCG is that it reduces hunger and cravings. However, this effect is more likely due to the dietary changes accompanying HCG protocols, particularly the emphasis on higher protein intake and/or carbohydrate restriction, which can lead to ketosis. These dietary regimens are associated with diminished hunger sensation. It is not the HCG itself that reduces hunger, but the accompanying prescribed diet.
Methods of Taking HCG
HCG is available in various forms, including drops, tablets, and injections. However, their effectiveness and safety vary significantly.
HCG Drops: An Ineffective Delivery Method
HCG is often marketed as drops to be absorbed sublingually (under the tongue). However, the molecular weight of HCG is approximately 30,000 daltons, far exceeding the size of molecules that can be absorbed orally (approximately 1500 daltons). Even if drop formulations actually contained HCG, the protein molecule would pass into the stomach where it would be broken down into small peptides and amino acids by gastric acid-just like your dinner portion of chicken-again, no potential for biological action!
HCG Injections: Potential Risks and Limited Benefits
HCG can be administered by injection by a licensed physician under "off-label" use. However, doing so is not risk free. This medicine can increase chances of a multiple pregnancy. Some women using this medicine have developed a condition called ovarian hyperstimulation syndrome (OHSS), especially after the first treatment cycle. You should NOT use this medicine if you are at risk for a hormone-related cancer such as tumor of the breast, ovary, uterus, prostate, hypothalamus, or pituitary gland.
Homeopathic HCG: A Deceptive Practice
Homeopathic HCG products are based on the principle that disease symptoms can be cured by small doses of substances that produce similar symptoms in healthy people. However, all HCG drop formulations are inert, or having no pharmacological action, due to their high molecular weight. Moreover, it is the specific shape and structure of a molecule on which the hormone’s action depends. It would be impossible to “take a small dose” or “a segment” of a hormone and expect to cause any kind of biological action.

The Expert Consensus: HCG is Ineffective for Weight Loss
Numerous organizations and experts have voiced their concerns and skepticism regarding the use of HCG for weight loss.
FDA's Stance: Since 1975, The Food and Drug Administration has considered the use of HCG for weight loss to be fraudulent and requires labels for HCG to state: HCG has no known effect on fat mobilization, appetite or sense of hunter, or body fat distribution. HCG has not been demonstrated to be effective adjunctive therapy in the treatment of obesity. There is no substantial evidence that it increases weight loss beyond that resulting from caloric restriction, that it cases a more attractive or “normal” distribution of fat, or that it decreases the hunger and discomfort associated with calorie-restricted diets.
FTC's Action: In 1976, The Federal Trade Commission ordered the Simeon Management Corporation, Simeon Weight Clinics Foundation, Bariatrics Management Corporation, C.M. Although the order did not stop the clinics from using HCG, it required that patients who contract for the treatment be informed in writing that: These weight reduction treatments include the injection of HCG, a drug which has not been approved by the Food and Drug Administration as safe and effective in the treatment of obesity or weight control. There is no substantial evidence that HCG increases weight loss beyond that resulting from caloric restriction, that it causes a more attractive or “normal” distribution of fat, or that it decreases the hunger and discomfort associated with calorie-restricted diets.
American Society of Bariatric Physicians' Opinion: In 2009, The American Society of Bariatric Physicians issued a position statement which stated: Numerous clinical trials have shown HCG to be ineffectual in producing weight loss. HCG injections can induce a slight increase in muscle mass in androgen-deficient males. The diet used in the Simeons method provides a lower protein intake than is advisable in view of current knowledge and practice. There are few medical literature reports favorable to the Simeons method; the overwhelming majority of medical reports are critical of it. Physicians employing either the HCG or the diet recommended by Simeons may expose themselves to criticism from other physicians, from insurers, or from government bodies.
Scientific Studies: A meta-analysis of eight controlled and 16 uncontrolled trials that measured the effect of HCG in the treatment of obesity shows no benefit to using HCG. It was concluded that there is no scientific evidence that HCG is effective in the treatment of obesity; it does not bring about weight-loss of fat-redistribution, nor does it reduce hunger or induce a feeling of well-being.

The HCG Diet Protocol: A Closer Look
The HCG diet typically involves three phases:
- Loading Phase: This phase involves consuming high-calorie, high-fat foods for a couple of days while starting HCG administration (injection, tablet, or other form).
- Weight Loss Phase: This phase is the most restrictive, involving a 500-calorie per day diet for 3 to 6 weeks while continuing HCG administration. The diet typically consists of lean protein, non-starchy vegetables, limited fruits, and minimal carbohydrates. Common food choices include chicken, fish, lean beef, spinach, asparagus, broccoli, apples, oranges, strawberries, and Melba toast. Butter, oils, and sugar are strictly avoided.
- Maintenance Phase: HCG is discontinued, and food intake is gradually increased while avoiding sugar and starch for three weeks to stabilize weight.
The diet lets you have two meals a day: lunch and dinner. Each meal has to include one protein, one vegetable, one bread, and one fruit. You can broil or grill veal, beef, chicken breast, fresh white fish, lobster, crab, or shrimp as long as you don’t eat any visible fat. No salmon, eel, tuna, herring, or dried or pickled fish are allowed. Vegetable choices include spinach, chard, chicory, beet greens, green salad, tomatoes, celery, fennel, onions, red radishes, cucumbers, asparagus, and cabbage. Bread can be one breadstick or one piece of melba toast. For fruit, you can choose an orange, an apple, a handful of strawberries, or half a grapefruit. The diet allows as much water, coffee, and tea as you want. You can also have up to 1 tablespoon of milk per day. You can use sugar substitutes but not sugar to sweeten drinks. Butter and oils aren't allowed.
Safer and More Effective Weight Loss Strategies
Given the lack of evidence supporting the effectiveness of HCG for weight loss and the potential risks associated with it, it is crucial to explore safer and more sustainable strategies. These include:
- Balanced Diet: Focus on consuming a variety of nutrient-rich foods, including fruits, vegetables, lean proteins, and whole grains.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week, along with strength training exercises.
- Portion Control: Be mindful of portion sizes to avoid overeating.
- Hydration: Drink plenty of water throughout the day.
- Stress Management: Practice stress-reducing techniques such as yoga, meditation, or spending time in nature.
- Professional Guidance: Consult a registered dietitian or healthcare provider for personalized advice and support.
