Allowing adequate rest intervals between meals, such as five to six hours, is beneficial.

Original passage

In many cases the faintness that leads to a desire for food is felt because the digestive organs have been too severely taxed during the day. After disposing of one meal, the digestive organs need rest. At least five or six hours should intervene between the meals, and most persons who give the plan a trial will find that two meals a day are better than three.
