I was wondering about this. For example, I'd have a schedule like this:
Monday - Lifting - 500 calorie surplus
Tuesday - Off/Cardio - 1000 calorie deficit
Wednesday - Lifting - 500 calorie surplus
Thursday - Off/Cardio - 1000 calorie deficit
Friday - Lifting - 500 calorie surplus
Saturday/Sunday - Rest - 1000 calorie deficit both days
This adds up to a 2500 calorie deficit each week, so around 3/4 of a lb, which is a safe steady loss. My question is would this have any positive effect that I wouldn't get from simply doing a 400-500 calorie deficit each day? Would the 500 calorie surplus on the lifting day have any effect on muscle/strength gain or would it be offset by the deficit on the following day? Could this type of diet help to not damage metabolism through long term deficits, or would I still end up with the same plateaus due to metabolism changes? I've no idea on the science behind this kind of thing, it's just a thought I had today.
