To control what is enough Atle tells you to buy a belt. That is a small investment. Your waist line is not the same before eating and after eating. You mark off three holes in the belt. If you have to go up to hole number 4 you know you should eat a bit less.
As quite a lot of people put on kilos (maybe without knowing why?), they only have to cut down on eating to go on using only three holes in the belt.
A belt is a small investment. It will save you a lot of money which you can use for other things.
If you want to you can donate some of the money to Atle. On request he will give you the number of his bank account.
