Hcg diet


The HCG diet is a weight loss method involving a very low-calorie diet and a prescription drug called human chorionic gonadotropin (HCG).

HCG is a hormone that is naturally made in the body during pregnancy. People who promote the HCG diet claim that it helps with weight loss and moving fat from the thighs and buttocks to other parts of the body. But studies have shown that this does not happen.

People use the HCG diet for weight loss, but there is no good scientific evidence to support any use.

HCG is an FDA-approved drug for certain conditions, but not for weight loss. Despite this, HCG weight-loss products continue to be available online and in weight loss clinics. They're often marketed as "homeopathic." The FDA warns consumers to avoid HCG diet products.
The HCG diet is possibly safe when used under medical supervision. The drug HCG can cause side effects including headache, fatigue, irritability, restlessness, and depression.

Special Precautions & Warnings:

Pregnancy: The HCG diet is likely unsafe when used during pregnancy. The HCG drug used during the HCG diet can cause birth defects.

Breast-feeding: There isn't enough reliable information to know if the HCG diet is safe during breastfeeding. Stay on the safe side and avoid use.

Prostate cancer: The HCG diet should not be used by people with prostate cancer. The drug HCG might make prostate cancer worse.
