Dear Anthony,
6 years ago, when this body here had the same age as you, it ate exactly as much as you are describing. Food that would be enough for 3-4 people was taken in daily until the body couldn't breath anymore =P
Intense spiritual practices also gave more energy and willpower to eat even more.
Somehow over the years this solved itself out and the amount of food is normal or compared to some even a little bit below. The intese wish to eat has disappeared physically, so there was nothing done to handle the situation psychologically, as it never worked out anyway =P
One note though: doing a lot of kumbhakka and going deep into silence both were catalysators of "eating-more". Regulating them to a more easy niveau also balanced this happening.
Over the years the body out of itself started looking for more easily digestable food and stopped eating the other kind or just eats from time to time as needed.
Easily digestable for this body here is:
Bread, rice, potatoes, fresh fruits in any amounts.
Vegetables, salads in medium amounts, except the most fluid ones like tomates which the body likes eating in any amount.
Oils from flowers, corns and olvies, and butter from animals digest easily aswell.
Mediumly digestable:
Nuts, dried fruits/vegetables, but they are eaten in good amounts aswell, but not as frequent, just from time to time.
Digestion is hard with:
Noodles/pasta, meat, cheese, proteins in general. These are eaten only veeery rarely since ~1-2 years.
All the adaptation happened out of itself, so just practicing with self-pacing as needed and living life as it happens will sooner or later dissovle any "problems".
Happy going on =)
