Where is that?

Although you are right.

But how many people use it. My thoughts

It's too greasy in the morning. Have some porridge and pickles. At noon, you must be full, not rich but nutritious, and try to eat as little greasy as possible at night.

Eat something light.

It helps to lie and digest. Remember not to eat too much at night! Put a burden on the stomach! A day should have a reasonable collocation.
