My brother , 26yr, civil engineer, works at a private firm and usually undergoes tremendous work pressure ( generally leaves for office at 9.30am and returns back home at 9.30pm) He weighs - 60kg Height - 5'7" Exercise- almost regular at gym Body structure - normal to lean built Food habits- normal He has inhibitions for quite a few food items {e.g. he will not eat 1 whole egg boil as he thinks yolk does no good, but a young man (with no health problem,normal to lean built,with strenuous daily life) can perhaps have that,no butter/ghee } and a bit of food tantrums here and there. Water intake- normal Sleep- mostly 6hrs Food- rice/roti/dal/fish/egg-ocassionally/chicken Fruit - mostly 1apple a day/a few grapes Suggest a healthy diet for him which will be easy to follow even in his hectic schedules.
