The man engaged in muscular work requires plenty of food; he can digest foods which the professional or business man, or the man of sedentary habits, cannot. He will probably be able to drink coffee and tea without any disturbance to nerves or to digestion. In his muscular work he liberates the waste freely and needs fats, starches, and sugars to supply the heat and energy. This is especially true of men who work in the fresh air; the muscular action liberates waste and heat and the full breathing freely oxidizes the waste, putting it in condition to be excreted through lungs, skin, kidneys, and intestines.

He should have more meat, eggs, and nitrogenous foods, and he also needs more carbonaceous foods to supply heat and energy, as given in Diet V. Three hearty meals a day are necessary.

His muscular movements keep the circulation forceful and the vital organs strong so that his diet may be almost as heavy as that of the football player. Meat or eggs, twice a day, with tea or coffee, and even pie may be eaten with impunity. He needs a good nourishing breakfast of bacon and eggs or meat, also potatoes, or a liberal allowance of bread and butter, corn bread, muffins, etc.
