Simply implementing the 500 calorie diet simply won’t work as the body is surviving on 500 calories which can lead to many detrimental side effects which includes harm to vital organs. Your body isn’t getting the daily nutrition for survival and as a result, it goes into starvation mode. This is the main reason that implementing the low cal diet is dangerous. It might even lead to loss of muscle mass.
When you include hCG in your diet, it will use the existing excess fat from the body especially from areas such as thighs, under the arms, stomach etc. It will also increase the energy levels and tricks the hypothalamus to thinking that you are full. As a result, you will feel less hungry and the hCG utilizes the excess body fat to add along with the 500 calorie diet that you take.
As a result, you will lose weight proportionately. Hence, always follow the 500 cal diet along with HCG.
