They have found times a day don't matter. Only breaking up the meals due to amount per sitting and your insolent sensitivity. I can't eat very big meals per sitting with out spiking insolent levels so I have to go with 5-6 meals to control my spikes other than post workout.
As posted earlier its all in and out per day, but you also have to use common sense and not eat all your daily macro's in one meal. lol
As a BBer you want to learn to control and manipulate your spikes.
