If you eat a nice and big meal in the evening and that you don’t wait 3 hours before going to bed, your body, while sleeping, will STOP THE DIGESTION WORK to concentrate on his main task in the night which is Repairing.
So your digestion will be set aside by your body, and will start ONLY in the morning once you wake up.
That’s why most people who eat a lot in their diner are not hungry at all for breakfast. Actually this is apparently the behaviour of almost all obese people.
Let your body perform his task without annoying it with digestion that it can’t handle in the night!
That’s why eating fish and little bit of veg is good. It is easy and fast to digest.
