The was a lot of interesting information, but enough cringe too. The chapter about the "health at every size" made go "ugh", if I may quote the authors themselves. The given statistic of 5-10% of US women over forty weighing more than 250 pounds is a scary one and should ring an alarm bell.
In the end, the authors talk way too much about stuff that does not help dealing with burnout. I wish they would have made their book more practical, rather than kept banging on about the various causes. But kudos for giving the advise on the utility of exercise at the very least.
