Not totally buying into that bashing of BL. They do put a heavy emphasis on cardio, but they also are lifting much. I think just that cardio stuff makes for 'better tv' than lifting maybe!
It is a show, for obese people, and they put them through more than what anyone could expect to do. Much has come out over the years and what they do is total extreme.
I think more harmful than what the show does is the so many myths out there about how to lose weight. One person will say this, one will say that, another will say something totally different.
Weight loss is a multi million, if not billion, dollar industry wanting overweight people to buy this book, buy that food, join this group, purchase this supplement. I started into the fasting thing last year and the backlash of some people say how bad it is because of the infamous 'starvation' mode.
In reality, for a vast majority of people, it comes down to burning more than you take in. Now, when you are getting to a certain point, or have a certain goal, you get much more technical but too many people make weight loss too confusing, too expensive and just make it too hard on themselves.
