With the huge number of diet programs out in the market, it is obvious that a lot of people are confused about which method is the best for them. Often they try many things, jumping from a diet to the other without real success. By that, they just affect their metabolism so negatively that their body suffers more than before.
It is true that there is no generic answer to the question "what is the best diet" that is valid for everybody. Otherwise you could just go to the doctor and he would give you the prescription, and your problem would be solved. There isn't just one way of doing it, and it also depends on the body, the personal habits, e.g. if you are a person who likes doing exercises regularly, and many other factors.
