Is Chorionic Gonadotropin Used for Weight Loss?
Chorionic gonadotropin, or hCG, is a hormone produced during pregnancy and approved by the FDA for treating fertility issues and certain hormonal deficiencies in men.[1] It is not approved or proven effective for weight loss. Claims linking hCG to fat reduction stem from the 1954 Simeons diet protocol, which pairs 500 daily calories with hCG injections, but no scientific evidence supports hCG's role in enhancing weight loss beyond calorie restriction.[2][3]
What Does the FDA Say About hCG Diets?
The FDA has repeatedly warned against hCG for weight loss, classifying it as unapproved and fraudulent when marketed that way. In 1976, the agency banned over-the-counter hCG products for obesity treatment, and in 2011, it cracked down on homeopathic versions sold online, citing no evidence of efficacy and risks of harm.[4] Legitimate hCG remains prescription-only for its approved uses.
Does hCG Actually Help with Weight Loss?
Clinical trials show hCG provides no advantage over placebo or diet alone. A 1995 meta-analysis of five studies found identical fat loss in hCG and control groups under very-low-calorie diets, with hCG users reporting more hunger.[5] A 2009 review in the British Journal of Clinical Pharmacology confirmed hCG does not mobilize fat or suppress appetite beyond starvation effects.[6] Any weight loss is due to the extreme 500-calorie limit, not the hormone.
What Are the Risks and Side Effects?
hCG injections can cause blood clots, ovarian hyperstimulation in women, and prostate issues in men. Diet-related risks include gallstones, electrolyte imbalances, fatigue, and muscle loss from malnutrition.[2][7] The FDA notes compounded or black-market hCG may be contaminated, leading to infections or inaccurate dosing.[4]
Why Do Weight Loss Clinics Still Promote It?
Some clinics market hCG drops, pellets, or shots despite bans, often as "hormone therapy" to skirt regulations. These products are typically homeopathic dilutions with negligible hCG, relying on aggressive marketing rather than evidence.[8] Patient reviews on sites like WebMD highlight short-term losses followed by regain and disappointment.[9]
Legal Alternatives for Weight Loss
Evidence-based options include FDA-approved drugs like semaglutide (Wegovy) or tirzepatide (Zepbound), which reduce appetite via GLP-1 mechanisms and show 15-20% sustained weight loss in trials.[10] Lifestyle changes—calorie-controlled diets, exercise—remain first-line without hormonal risks.
