I finished Burn! Not the easiest read but so worth it for the information. My husband and I listened to a podcast where Herman Pontzer was interviewed. The idea of fixed calories astonished me as it goes against everything I thought I knew about calories and matabolism. I knew I had to read his book. Six months later and many library checkouts later, I'm done!

This was not the easiest or most interesting read. There was a lot of science covered. I didn't always follow the flow of the text. I also missed the chapter on how to lose weight??? However, there was so much good information and I learned tons. I also enjoyed learning about the Hadza people.

Some random sections I highlighted:

That means you burn the same number of calories to run three miles at your fastest pace as you do to jog it casually--you just burn the calories faster (and finish sooner) when you run fast.

At around 5mph, the cost of walking exceeds the cost of running; it's actually cheaper to run at that speed than it is to walk.

...The total number of heartbeats in a lifetime are the same across species, from the tiniest shrews to the mightiest whales. We all get about one billion heartbeats.

Exercise is one way to maintain weight loss in a constrained energy expenditure world, allowing people who've lost weight to retain their old, pre-weight-loss daily intakes and expenditures without regaining weight. Exercise also seems to help the brain do a better job matching eating and expenditure.

We should all take responsibility for our diets, but overeating isn't simply a failure of willpower or discipline.
