Mystified About 2 weeks ago I started tracking calories to do a relatively clean bulk. I'm a 5-9 male at 138 pounds. To gain a pound a week in my active life I have to eat 2770 calories a day. Eating this much food is so hard to do. Even with treats like pizza and hamburgers its a struggle to get this much food in a day, yet hams do this their whole life to an extreme! I'm not sure they have any gag reflexes or shame.
