This book was surprisingly boring. I don't really think of myself as a health-conscious person, but apparently I read a lot on this topic, because I seem to already have a very solid opinion on almost everything this guy has to say. Some I adamantly agree with, and some I adamantly disagree with.
- "Sleep more"? YES!!! Absolutely! He's right!
- "Sugar is bad for you"? Clearly true, though I eat it anyway.
But...
- "Red meat is bad and should be avoided"? No!
- "Every bite you take matters"? Screw you, guy--that is not a healthy attitude! I have enough perfectionism in my life already!
- "Stigmatize sinful foods"? OMG, don't even get me started. Food is not a fucking sin! At worst, it's a bad decision. If you look in Leviticus, there is nothing that says anything like "...and thou shalt not eat brownie sundaes, for then thou shalt have a fat butt and be an abomination." Eating dessert does not not make you a bad person! I'm convinced this whole attitude that food is something to feel guilty about causes more problems than all the junk food and artificial sweeteners put together.
One major problem with this book is that he cites a lot of good studies (that somehow I've already read about many times before) but then draws wildly unsupported conclusions from them. For example, he talks about a study that found a correlation between aggression and eating a lot of trans-fat (p. 108). Good, but he uses it to admonish readers to avoid fat. What? Maybe avoid trans fat, but all fat?! Just a few chapters ago, he was telling us to get a lot of omega-3s. Newsflash: that's also fat.
An especially funny one is when he cites a study where they measured people's arteries, then fed one group a "meal consisting of a sandwich with sausage, egg, and cheese and three hashbrowns."
"After eating just one poor meal, the arteries of participants in this group dilated 24 percent less than their original state. This study suggests that every meal influences your body's ability to function properly." (p. 198, emphasis the author's)
OMG!!!!!11one!! Since I'm sure this was the first time these people ever ate a sausage, egg, and cheese biscuit, and obviously their arteries never went back to normal later, they'd better be careful never to eat another one ever again! This study suggests that if they ate that three more times, their arteries would close up entirely! Everybody ruuuuuun!!!!
Less hysterically but with a similar lack of critical thinking, he rags on dried fruit. It's unhealthy! Look at all those carbs and sugar! Um, dude, are you talking about the naturally occurring fructose that would also be found in the wet version of the same fruit, which you say is healthy? Or are you actually talking about the sugar that manufacturers add to things like dates and craisins? To me, those are two different animals. He also claims that the nutrients are lost from fruit in the drying process--no support for that claim whatsoever.
I'm alarmed to see from the bio that this author is a science advisor to Gallup and serves in several other science-related roles, because this book really seems like it should have been checked over by someone with a rudimentary understanding of science--at least to the level of "correlation does not imply causation."
From there, he goes on to commit one of my big peeves: observing what works for him and concluding that's what everybody should do. I agree that there are some universals. Everybody needs to sleep, everybody needs to eat. But just because you feel like crap after eating eggs Benedict doesn't give you the right to prescribe yolkless omelets for everyone else from now on. Our bodies are different. Some people can get all the nutrients they need from plant sources, some people need to eat meat. Some people can't tolerate dairy products, some thrive on them. Don't overgeneralize, and don't judge.
Overall, I think this book drags on way longer than it needs to, probably for the purpose of making it fill up a 30-day program. Apparently, the book designer agreed: there's a little progress bar at the bottom of each page, letting you know how much more book is left to slog through. (Note to the book designer: for print books, people can get this information just by comparing the thickness of the pages read to the thickness of the pages remaining. There's no need to add a Kindle-like display at the bottom. Thanks though.)
Notes:
p. 147 Study: mice genetically programmed to age rapidly. Non-exercising mice got frail, decrepit, gray hair, and all died in the first year. Exercising mice (ran on wheel 45 minutes 3x/week) stayed strong, didn't get gray fur, and none died in the first year. I wish they had used a third group where the mice just walked, but I guess mice aren't really into that. But I would be interested to know how much of the effect was from running and how much was just from moving at all.
p. 153 The enjoyable part of a workout for most people is after they're warmed up but right before they get to "ventilatory threshold"--the part where breathing is difficult enough that it becomes hard to talk. That would explain why runners like running--once you get in shape, you can spend a lot of time there if you want to. It also explains why I really enjoyed Couch to 5K when I spent several weeks on each "week."
p. 154 "Intense activity triggers the release of brain chemicals called endocannabinoids, which create a potent feeling of pleasure. When this is tested in the lab by having people either walk or run on a treadmill for 30 minutes, running more than doubles the level of endocannabinoids released in the brain." Day-um!
