I doubt every hour would be a good idea. The meals would be so small that you would *never* get even a partial feeling of fullness, which is something that a lot of people need to stay sane.
For the last 2 weeks I've been living on 5 meals per day, each meal exactly 3 hours apart, each meal consisting exactly of the following:
1 scoop whey
5 triscuits
1 tbsp ANBP
Plus some cottage cheese, fish oil, and a multivitamin before bed.
This is for cutting, and I never feel hungry on it, even at only 1700kcal.
