Eat supper earlier and earlier, until you're eating around five PM.
This lets the stomach do its business before you go to sleep and you will sleep better.
If you become hungry in the evening, drink a glass of skim milk, or two or three. No solids. As the diet progresses, you will find it easier and easier to get up in the night.
There will not be fat molecules wandering around in the blood at night looking for a home. The heart will work better. As the arteries serving the brain clear, the brain may start to think more clearly.
Drink a glass of skim milk for breakfast and you may not need food until lunch. The wish for breakfast may not appear until you are truly hungry.
