Im pretty sure i understand the theory of a pro/carb meal after workin out to get an insulin spike. But besides this, is there any good reason to purposely be consuming carbs on a cut cycle? For instance, i see alot of people including oatmeal in the mornings. My diet roughly consists of protein shakes and water, tuna, chicken, lean beef, egg whites, and maybe some f. free cottage cheese, rotating these foods from day to day to meet protein and caloric requirements. I never purposely consume carbs except post workout.

If so, why would i want to do this? (purposely add carbs to my cutting diet)
What time of day should they be consumed at?
What are specific examples of these carbs?

Thanks for the help guys,
