MS, you brought up something that's sort of been tickling at the back of my brain.
During the week, my diet is very clean on carbs. About 250 grams/day, almost all from oatmeal, whole bread brown rice, etc.
Weekends are a different story. I go through a bag of jelly beans, Spree, and some other hi-GI, no fat stuff.
This has worked great for fat loss, and seems to be working well for adding some mass now, too (really, too soon to tell on that yet).
But am I screwing myself with this? I know at times I get kind of zoned out on the weekends. Just wanted your thoughts.
