If you aren’t cutting and have a high calorie intake the partitioning is ridiculous. Sure,it may be better to restrict fat intake in a workout shake, or less carbs in your pre-bed anticatabolic shake, or you may feel you want a shake that goes down easy when you wake up and has a low fat content-but beyond that, it doesn’t makes sense unless you are cutting.
What is the point of it? To maintain more stable insulin levels and be able to eat more food without fat gain are the main arguments.
Well, not only does partitioning have no effect on body composition or fat loss, but for someone with a higher allowed carbohydrate intake it can actually result in LESS stable insulin levels from the constant fluctuation in macro intake, the exact opposite of the intention of the plan. There are studies to back this up.
If I am cutting, I end up “partitioning”, but that’s because I have less carybohydrates in my diet and naturally will end up having meals without many of them because most of my CHO intake is earlier in the day when my body is active and needs them most. If you are taking in hundreds of grams of carbs like you should be if you are trying to gain mass, the massive plan would suggest that you have 75+g of carbs over a few of your meals and then close to none in other meals not surrounding your workout- do you really think that is a good idea? Look at the massive changes in calorie and macronutrient intake, do you honestly think that will be better for maintaining insulin sensitivity?
Odds are you should probably be eating healthy foods with each meal in a balance you feel your body responds well to at the time of day and not worrying about splitting up your macros and what to eat when. Try to find a SINGLE athlete who does this. There are NONE. Even most bodybuilders don’t do this, and the massive eating type approach is supposed to be intended for them. That’s because it just doesn’t make sense. It’s a fad that caught on and they’ve been milking it for a while, but in most cases it isn’t practical and should never be the reason for your food choices.
That got a little long but that’s my opinion on this whole mess. You wanna get big, lift lots of heavy weights and eat lots of healthy food and don’t BS yourself with irrelevant details.
