The HCG (human chorionic gonadotropin) diet has become an increasingly popular and controversial weight loss method. This ultra-low-calorie diet calls for severe calorie restriction paired with HCG supplements or injections. Proponents claim you can lose a pound per day on the diet without feeling hungry. However, mainstream health experts have many concerns about the safety and efficacy of this diet. Where did the HCG diet originate and what is the science behind it? Let’s take an in-depth look at the origins and evolution of this radical diet approach.
History of the HCG Diet
The HCG diet was first developed in the 1950s by British endocrinologist Dr. A.T.W. Simeons.
Dr. Simeons’ Early Research
While studying pregnant women in India on severely calorie-restricted diets, Dr. Simeons made a surprising observation. He noticed these pregnant women were losing abnormal fat deposits instead of precious muscle and structural fat. This occurred even while the fetus continued to grow normally. Dr. Simeons hypothesized that the HCG hormone, which is produced during pregnancy, might be protecting the mother’s structural fat and muscle mass. He theorized the HCG was tapping into the abnormal fat reserves to nourish the growing fetus.
Initial HCG Diet Studies
To test his theory, Dr. Simeons began experimenting with giving obese patients small doses of HCG along with restricting calories. The results were striking. Over several years of testing and refining, Dr. Simeons concluded that his HCG diet protocol resulted in rapid fat loss without the hunger, weakness, and muscle loss expected from very low-calorie diets. In 1954, Dr. Simeons published his groundbreaking paper “The Action of Chorionic Gonadotrophin in the Obese” in the Lancet, detailing his HCG diet theories and clinical results. He followed up with his seminal manuscript “Pounds and Inches” in the 1960s, laying out specific protocols for the HCG diet that are still followed today.
Key Components of Dr. Simeons’ HCG Diet
Dr. Simeons’ original HCG diet protocol consisted of two main components:
- Very low calorie diet – Restricting calories to just 500 per day
- Small doses of HCG – Typically injected daily or taken as oral drops
The ultra-low-calorie diet was intended to encourage rapid weight loss. The HCG hormone was proposed to reduce hunger, boost metabolism, and trigger the breakdown of abnormal fat deposits. The diet consisted of three phases:
- Loading Phase – Eating high calories and fats
- Weight Loss Phase – Taking HCG and restricting calories
- Maintenance Phase – Stopping HCG and slowly increasing calories
Evolution of the HCG Diet Over the Decades
In the decades after Dr. Simeons introduced the HCG diet, it went through periods of popularity and obscurity.
Resurgences in Interest
In the 1970s, several studies tested the HCG diet but did not find conclusive evidence of HCG’s effects separate from the very low-calorie diet.
Interest surged again in 2007 when Kevin Trudeau promoted the diet in his book “The Weight Loss Cure”.
In 2009, Dr. Oz introduced the HCG diet to viewers of his popular TV show, triggering another spike in popularity.

Safety Concerns Emerge
As the HCG diet gained followers, concerns also grew among mainstream health organizations about potential risks:
In 1976, an American Journal of Clinical Nutrition study found no evidence that HCG provided additional weight loss beyond calorie restriction alone.
The FDA expressed concerns about the extremely low 500 calorie diet and unproven supplement claims.
By 2011, the FDA banned the sale of over-the-counter HCG supplements and required label warnings about the diet’s risks6.
Today, debate continues over the safety and effectiveness of the HCG diet. But thousands still undertake this restrictive regimen annually in hopes of fast weight loss.
HCG for Weight Loss Today
Currently, the HCG diet remains controversial but popular. Modern versions look similar to Dr. Simeons’ original protocol but with some modifications:
- HCG doses used today are typically lower than Simeons’ original recommendations.
- The very low 500 calorie diet is sometimes increased to 800 calories to improve safety.
- Phases may be shorter in duration to reduce health risks.
- New HCG supplement forms like sublingual drops, pellets, sprays, and lozenges are often used instead of injections.
There is still no conclusive evidence that HCG provides additional weight loss effects separate from severe calorie restriction. But modern diet practitioners claim it can help suppress hunger, reduce fat deposits, and promote quick weight loss with fewer side effects when properly supervised.
Is the HCG Diet Right for You?
The HCG diet provides a powerful tool for rapid weight loss. However, the extremely low calorie diet and HCG supplements pose potential health risks that each dieter must carefully consider. Here are some key factors to weigh when deciding if the HCG diet could be suitable for your needs:
- Consult your doctor – Get their approval before starting any very low-calorie diet.
- Consider your health history – Make sure you don’t have any conditions that could be aggravated by the diet.
- Check your motivation – The diet requires high commitment. Are you ready?
- Get professional supervision – Work with an experienced HCG provider to ensure safety.
- Follow protocols closely – Don’t attempt the diet without guidance.
- Watch for side effects – Stop if you experience adverse reactions.
- Make lifestyle changes – Adjust your nutrition and exercise habits for long-term success.
For those who qualify medically, commit fully, and get professional supervision, the HCG diet can deliver fast results. But it is absolutely not for everyone. Discuss your options with a doctor to decide if it could be a fit for you.

The Bottom Line
The HCG diet originated from the weight loss research of Dr. A.T.W. Simeons in the 1950s. Though controversial, it remains popular today as a rapid weight loss method. However, mainstream health experts have concerns about potential risks of the very low calorie diet and unproven HCG supplements. Always consult your doctor before attempting this restrictive regimen. When done correctly under medical supervision, the HCG diet can offer fast results for some. But it is not a panacea and carries health risks that each dieter must carefully consider.
