When was the last time you tried to lose some weight? Went on a diet for a couple of weeks, the scale didn’t move much and you just returned to your old habits?
Sticking to a diet is a bitch. No more than 20% are actually losing the weight and keeping it off.
But that 80% didn’t have my advice. You will not be in the 80%, you will be one of the few that have the knowledge to keep being on a diet for as long as they want.
