How much can you lose on HCG in 21 days

How the Diet Is Prescribed

The HCG diet is a very low-fat, very low-calorie diet.

It is generally divided into three phases:

Loading phase: Start taking HCG and eat plenty of high-fat, high-calorie foods for two days.

Weight loss phase: Continue taking HCG and eat only 500 calories per day for 3–6 weeks.

Maintenance phase: Stop taking HCG. Gradually increase food intake but avoid sugar and starch for three weeks.


While people seeking minimal weight loss may spend three weeks on the middle phase, those seeking significant weight loss may be advised to follow the diet for six weeks — and even repeat all phases of the cycle several times.

During the weight loss phase, you're only allowed to eat two meals per day — usually lunch and dinner.

HCG meal plans generally suggest that each meal should contain one portion of lean protein, a vegetable, a piece of bread and a fruit.

You may also get a list of approved foods to select from in specific amounts.

Butter, oils and sugar should be avoided, but you're encouraged to drink a lot of water. Mineral water, coffee and tea are allowed as well.


Does HCG Help You Lose Weight?

Proponents of the HCG diet claim that it boosts metabolism and helps you lose large amounts of fat — all without feeling hungry.

Various theories attempt to explain HCG’s weight loss mechanisms.

However, multiple studies have concluded that weight loss achieved by the HCG diet is due to ultra-low-calorie intake alone and has nothing to do with the HCG hormone (7Trusted Source, 8Trusted Source, 9Trusted Source, 10Trusted Source).

These studies compared the effects of HCG and placebo injections given to individuals on a calorie-restricted diet.

Weight loss was identical or nearly identical between the two groups.

Furthermore, these studies determined that the HCG hormone did not significantly reduce hunger.
