For a period of seven years I did not have the will to live. During this period I tried to control what I ate but could not. I often ate excessive amounts of food and then tried to get rid of what I had eaten.
The ability to control ones eating is not a function of what you are eating as much of a function as why you are eating what you are eating. The reason behind why people eat excessive amounts of food and/ or food that is unhealthy is often more important than what the people are actually eating.
If you become completely happy, peaceful and satisfied, you will no longer have as much trouble controlling your eating. The positive emotions required are beyond your ability to bring about, otherwise you already would have brought them about. It is possible to receive sufficient understanding so that you become more peaceful etc.
Pslam 29:11 The Lord gives strength to his people; the Lord blesses his people with peace.
