Medically it's unwise and unhealthy to eat less and smoke more expecially as a young dude who is fighting to keep fitness. Excessive  smoking will get you tired quick when doing your push up exercise, i will advise you eat more of healthy food including fruits too and smoke less if you are addicted to smoking.
