If that woman was a size 4 at the finale, loose skin and all, I'm the queen of England. This show sets unrealistic expectations and weight loss stories. Maybe the skin surgery wouldn't be necessary if they lost weight the healthy way, rather than "extreme" measures (losing 25% of your body weight in 90 days is ridiculous)
I'm torn with the run time. 60 min seemed too short and I didn't feel invested in her journey. 120 min is obviously way too long. Maybe 90 is the sweet spot?
