In brief: The hCG diet combines homeopathic pellets or hormone products with an extremely low-calorie diet. No additional weight-loss effect has been established for the pellets. Rapid weight loss results mainly from the large calorie deficit.
What does the hCG diet promise?
Claims include less hunger, targeted loss of stored fat and protection against weight cycling. At the same time, energy intake is often supposed to fall to around 500 to 800 kilocalories a day. These promises sound attractive but mix two entirely different factors.
People who consume very little energy lose weight in the short term, regardless of pellets. This does not establish a specific effect of hCG or a homeopathic dilution.
What do studies show?
Controlled studies have not shown a convincing advantage for hCG in weight loss, hunger or fat distribution during a weight-reduction diet. In addition, highly diluted homeopathic pellets often contain no detectable hCG.
Authorities therefore warn against unapproved hCG products for weight loss and their combination with extremely low-calorie diets.
Risks of very low-calorie diets
- Insufficient protein, vitamins and minerals
- Dizziness, fatigue and concentration problems
- Muscle loss rather than targeted fat loss
- Electrolyte disturbances and heart rhythm problems
- Gallstones and a higher risk of weight regain
Medically used very low-calorie programmes are different: they are provided to selected people for a limited time, using suitable products and under professional supervision.
How can you recognise responsible weight-management advice?
It does not promise precisely targeted fat burning or guaranteed weight loss. It considers illnesses, medicines, sleep, physical activity, eating behaviour and a realistic pace. What matters is a plan that remains workable after weight loss.
Conclusion
hCG pellets make a crash diet neither more effective nor safer. Sustainable weight reduction requires a diet that meets nutritional needs, enough protein, physical activity and medical support where appropriate. The hormone’s role is explained in hCG: medical uses and misuse.
People with substantial excess weight, eating disorders, diabetes, cardiovascular or metabolic conditions should seek professional support for weight reduction.
