People, despite being in their right mind, still keep on producing and consuming alcohol although they are quite aware of its extremely bad effect. Of course, it is not that you cannot reach out for it now and again - go for a little amount of it whenever being at parties or gatherings but don't drink it systematically since it will absolutely take a toll on your health!
Don't consume them either during or after meals since they contain carbon oxides acting against all our cells, taking a heavy toll on the brain cells. Also, they affect the lining of the stomach, shrink the blood vessels and are generally quite bad for one's health state.
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.
