They don't tell you about studies like that because the weight loss industry is a huge enterprise.
All along I have said people get fat purely and simply because they eat more food than they need.
If you want to lose weight then stop eating so much.
A mate took on a method where you eat every second day and drink only water on the alternate day.
He lost about 20kg in three months, no special diet, normal exercise, and no cost.
