Well, there is a lot of good stuff in there about over-the-counter fat burning pills - you need to be careful, look at the studies, etc ...
However, he makes the argument ... "Go walk your dog instead of taking a fat burner".
Why not do both?
I don't know man - it just seems like one of those arguments like ... "Hey, don't do squats!" ... because you don't need to do squats; you can satisfy your goals without squats; squats are dangerous; etc ...
But I like squats and they work for me. I like Fat Burners too ... especially taken before cardio.
