What are the basics of the separate nutrition plan? Eat simple food and don't combine such belonging to various types at one and the same time since it slows down the digestion.
Some foods are digested quite quickly unlike many others. Fruits, for instance, are pretty fast to digest (that takes only an hour after their consumption) since they go directly into the small intestine. The reason is that they contain ferments which boost the assimilation.
Don't combine sweet fruits with protein-loaded foods since the assimilation of the latter happens in an acidic environment. Besides, when combined with bananas, for instance, it will take a toll on the digestive process.
Just write down the basics of the separate nutrition program and get to stick to them for real! Make your own list of forbidden and permitted food combinations and try to remember them! Plan ahead your eating regimen for each day and dose properly (as we will think of foods as a medicine)
Even if you are not a programmer or an IT specialist, you can still "program" your consciousness, if you are willing to. As old as our habits are, it is quite hard to ditch them since we have been following them for many years; plus, we have got used to how some foods taste and even considered them healthy.
