Ahhh, so the main reason is compliance? I was thinking (before reading your explanation) that surplus/deficit is harder for compliance than just keeping calories the same every day. But I see what you mean in terms of being really strict is sometimes easier than "kinda sorta strict, oops, I just ate that whole donut" type mentality. Your work situation sounds pretty abysmal in terms of not eating all of the calories. And pretty ideal for fatties who wanna fat.
Btw, pretty fish move to binge on Fritos imo. M&Ms
though.
