Despite their boasts, Mark and Luke still had to adjust to the new lifestyle. The day after the first binge, they woke up feeling tired and terrible, but like any guy in a bet, committed to continue. Over the course of a week, they did settle into a pattern. The guy at their burger joint now knew them by name, and they noticed that he always seemed to have some cancelled order that doubled the size of what they paid for.
The fridge, which they had entirely cleaned out over the course of three days, was restocked with everything microwaveable and unhealthy. They bought loads of snack foods but couldn't seem to keep them in stock, since every time even the largest bags would be opened, they wouldn't last 20 minutes.
Luke, by past history, did settle in faster to the lifestyle. The third day, he was putting away much more food than he had before. leaving Mark behind. After only a week, not an enormous amount was showing, but you could see it through his clothes. Luke had bought tightly fitted clothes to show off his chiseled body when he had gotten fit; now they were serving to show off every pound he put on. His t-shirt no longer came over the top of his jeans, and the tiniest bit of midriff showed. A treasure trail led up into the hint of a starter belly, that became more than a hint when he was stuffed. His pants were tighter, and mostly in the butt. You could see from up close it was becoming a struggle to put them on.
Mark was never one to be left behind. He always ordered as much as Luke at the burger joint, and tried to catch up with him everywhere else. Luke may have led the way after three days, but Mark's shear determination was leading him to catch up. Just to help, Mark stopped by the nutrition store early on in the week and picked up a protein weight gain formula. He had two shakes every night right before sleep, to make sure that he wouldn't fall behind.
In fact, Mark ended up being ahead. The protein shakes right before bed went straight to his body, and he was in the same position as Mark. His shirts showed a hint of midriff, his pants tighter than before, and his arms looked slightly less defined.
Both boys were still determined to win.
