What Are HCG Injections?

HCG (Human Chorionic Gonadotropin) is a hormone produced during pregnancy that has been marketed as a weight loss aid when combined with an ultra-low-calorie diet. Although it has gained popularity, it remains controversial and is not FDA-approved for weight loss.

How Do HCG Injections Work for Weight Loss?

Proponents claim that HCG injections:

  • Suppress appetite

  • Help preserve muscle mass

  • Boost metabolism

However, these claims lack strong scientific backing. The main driver of weight loss in HCG protocols is the extreme calorie restriction—often as low as 500-800 calories per day.

The HCG Diet: What to Expect

Phase 1: Loading Phase

For 2-3 days, individuals are encouraged to consume high-fat, high-calorie foods while beginning HCG injections.

Phase 2: Low-Calorie Phase

This phase typically lasts 3-6 weeks, requiring strict adherence to a 500-800 calorie daily intake while continuing HCG injections.

Phase 3: Maintenance Phase

Gradually, caloric intake is increased, but carbohydrates and sugars remain restricted.

Scientific Backing: Does HCG Help With Weight Loss?

Several clinical studies have debunked the effectiveness of HCG injections for weight loss. Research indicates that:

  • Weight loss is due to calorie restriction, not HCG itself.

  • There is no significant difference in weight loss between those using HCG and those following a low-calorie diet alone.

  • The FDA has issued warnings against HCG diet products, stating that they offer no proven benefits.

Risks & Side Effects of HCG Injections

HCG injections come with potential risks, including:

  • Fatigue and dizziness

  • Nutrient deficiencies due to severe calorie restriction

  • Increased risk of blood clots and hormone imbalances

  • Gallstone formation due to rapid weight loss

The FDA has labeled over-the-counter HCG products as fraudulent and illegal for weight loss purposes.

HCG Injections vs. FDA-Approved Weight Loss Medications

For those seeking medically supported weight loss treatments, FDA-approved options such as GLP-1 receptor agonists like Saxenda (Liraglutide), Mounjaro (Tirzepatide), and Zepbound (Tirzepatide) have demonstrated clinical efficacy in aiding weight loss while preserving lean muscle mass.

Should You Try HCG for Weight Loss?

Given the lack of scientific evidence and FDA warnings, HCG injections are not recommended for weight loss. Instead, consider safe, evidence-based weight loss treatments or consult with a healthcare professional about medically supervised options.

Final Thoughts: HCG for Weight Loss – Worth the Risk?

While the HCG diet may lead to short-term weight loss, it is primarily due to extreme caloric restriction and is not a sustainable or scientifically supported method. If you’re looking for an effective and safe way to lose weight, FDA-approved treatments and lifestyle changes are a more reliable approach.
