Before listing the numerous bad points I have to say there is one point about this show that is so amazingly good it almost makes up for the bad ones: it demonstrates with no doubt whatsoever that nearly ANYONE CAN BE ACTIVE no matter what their weight. A good deal more active than most people believe is possible. This is so important. It shows that change is possible. It also shows how people who do eat well and exercise can accomplish amazing things well before they reach their goal weights, that there are rewards for changing your lifestyle throughout the journey, not just when you reach that magical number you've been striving for on the scale.
Among the bad points are the cheap psychoanalyzing that goes on, which appears to be more for making drama moments than actually accomplishing anything constructive, product placements (especially for products one strongly doubts the trainers actually encourage the contestants to use), the necessity for some contestants to lose more weight than is healthy in order to win, and raising unrealistic notions of what constitutes an appropriate rate of weight loss or level of intensity of exercise would be safe for viewers at home without strict medical supervision.
