should be aiming for is roughly 40% of carbs, 40% protein and 20% fat.What about calories; don't those matter?lories aren't as important but what you shoProGain 350uld be looking for in terms of the amount of calories is an alternating pattern. You want low calories (about 2,000 for men and 1,200 for women) for 2 weeks followed by higher calories for 2 weeks (about 2,500 for men and 1,500 for women).http://www.supplements4help.com/progain-350/
