The Chazon Ish was asked how he overcame his love for food. He answered that if Torah is geshmak enough then food loses its hold over you. He was once asked if he ate breakfast that day and he said that HE DOESN'T REMEMBER[!!]. He explained that if he is served a meal by his wife then he assumes he hadn't yet eaten. Otherwise, he has no way of knowing!!
