I caught a couple of episodes of We channel's Diet Detective yesterday. Never heard or saw that before.
It's a guy who goes to the home of an overweight person (who's applied to be on the show), spends a week with him/her (both were hers in the episodes I saw), goes over diet, exercise and discusses emotional issues with them, then comes back 13 weeks later to see if there's been any progress. The first woman lost 37 lbs (training for a triatholon), the second 0 (I'm not sure why she even applied for the show, she seemed totally unwilling to do anything he suggested, and even showed up 2 hours late to meet him at the gym.
at the end of the second show he said he recommended 90 minutes of cardio for anyone 70 lbs or more overweight 5 to 6 times a week, then resistance 3 times. wow, that sounded like a lot of cardio to me for someone starting out with that much weight to lose. not sure I would have been able to stick it out. what do you think?
