Maintaining your weight below your set point is like trying to walk on a never-ending tightrope. No matter how good you are, you will eventually slide off.
And even before falling, you will be obliged to constantly scrutinize and limit what you are eating. Instead of living on a tightrope, could you envision letting your body stabilize itself at the weight that was predetermined by nature? At that point, there will no longer be a need for vigilance and constant control.
