Devising a diet
- Food intake should be consistent but should take into account lifestyle and physical activity.
- The total daily energy intake should be distributed consistently with at least three regular meals each day.
- Total energy intake must be individualized, because it varies with age, sex, and body weight and is affected by physical activity. It can also be greatly altered by illness. (Dietitians employ standard methods to estimate daily energy requirements. One of these methods is the Harris-Benedict equation.)
