An old Russian proverb says you should "Eat your breakfast alone, eat your lunch with your friend, give your dinner to your enemy." A new school of dietitians would have it, therefore, that missing dinner twice a week actually contributes not only to the patients' weight loss, but also to their general health.

The new school of dietitians' argument is based on which of the following assumptions?

A. While the Russian proverb argues that dinner is a problematic meal, it does not promote forsaking it altogether.

B. Eating dinner with enemies is a sign of reconciliation, which may improve one's health.

C. While eating solids is to be encouraged at breakfast and is permissible during lunch, Dinner should contain only fluids.

D. The Russian proverb states that one should give his dinner to his enemy, so that one never has dinner.

E. Russian metabolism works differently from western metabolism, and therefore while for the Russian the evening meal is merely problematic, the westerner should actually do without it.
