The program is geared toward people with absolutely no attention span and offers little useful information. Mostly sensational in its format, the presentations are geared toward selling a nutrient, micro nutrient, or "procedure" being marketed by the guests. Medically and scientifically, the show has huge gaps.
The games he used to have at the end, "Jeopardy-like" were abandoned this season -- and good riddance. They made a mockery of both the contestants and the issues being addressed -- the games were supposed to be substantive, to teach the viewer something. They always fell short.
A final observation: there is rarely any follow up with the guests who've had to lose considerable weight, or whom he's challenged to make major changes in lifestyle. Why? Doesn't he/producers believe in what they're doing? Let's see these successes (or not) and work harder to help them, rather than just making 'examples' out of them on TV.
