"Soon the scale hit 265. Mr. Cahill started weighing and measuring his food again and stepped up his exercise. He got back down to 235 to 240 pounds. But his weight edged up again, to 275, then 295.

His slow metabolism is part of the problem, and so are his food cravings. He opens a bag of chips, thinking he will have just a few. “I’d eat five bites. Then I’d black out and eat the whole bag of chips and say, ‘What did I do?’”"

The article is light on the details post-TBL, but it sounds like recidivism in terms of diet is probably a major root cause of weight gain. Also, maybe it's hard to tell whether they're doing steady-state cardio or high-intensity interval training (steady-state cardio has been shown to paradoxically cause weight gain in people). In any case, it sounds like they need more guidance and check-ins post-show.

"He opens a bag of chips, thinking he will have just a few."

Thats the problem right there. Don't have things like that in your house.

Want a snack, try raw carrots or broccoli, by the time you finish binging you would have consumed about 50 calories :)
