Food intake in Antarctica
1. Body-weight, skinfold thickness and food intake were measured at regular intervals in twenty-five young men while on an Antarctic expedition. 2. The mean calorie intake over the year was 3600 kcal/man per day; 12.1% of these calories were supplied by protein, 39.8% by fat, and 48.1% by carbohydra...
