The HCG diet was first invented by Dr. A.T.W Simeons. When he was in India researching pregnant women he noticed a strange relationship. He found that lean mother conceived lean children. And later after further research he found lean mothers had high amount of Human Chorionic Gonadotropin.
Human Chorionic Gonadotropin (HCG) is a hormone secreted by pregnant women. This hormone is responsible for the sustainable growth of fetus.
But when Dr Simeon found this relation he invented the HCG diet program.
In this HCG diet program one has to consume HCG solution along with adhering to low calorie diet.
He formulated three low calorie diet. The first is 500 calorie, second 800 and third 1200 calorie.
In modern times people have added 1500 calorie diet.
The idea is simple.
Take HCG solution orally or through injection and eat low calorie diet.
The HCG diet requests that you prohibit some kind of foods .
Moreover, the diet comes in four phases. And each phases take some day to complete.
While taking the HCG drop the hypothalamus of your brain is changed. In other words it is reseted.
for instance, you must be used to consuming sugar and high amounts of carbs. When you get started on the HCG diet your sugar and carb is greatly restricted. And consuming HCG solution while eliminating some foods makes you total aversion from the same.
Therefore, when you complete HCG diet, apart from losing weight, you will also gain food aversion to high fatty foods.
So, HCG diet is completely natural and with no to minimum side effects. Best part is that when you lose weight you keep those weights off for your entire life.
