While reading it, it read more like Freakanomics than an encyclopedia of "how to lose weight". Its more about heres some cool shit i/we've saw happening, heres what we did, try it out. He never advocates heavy drug use or any of that shit. He even mentions: "Medication = can give you weight loss, but trade off is long term damage to your body"

Now heres one interesting thing... if you think "eat whatever you want and you will lose weight" is bullshit, consider this: I used to love drinking soda. Drank it by the gallons. I stopped due to weight gain. Now I don't crave it, I am mostly repulsed by it, and am quite happy just drinking water, in fact I can drink whatever I want because I want water.

Over time your mindset will change, you simply got used to a lifestyle of excessive eating and thus... "I don't want to give up my donuts in the morning". Just eating fruits daily makes me repulsed by eating processed sweets (donuts and the like) because there is so much more and better flavor out there that is not due to just adding tons of sugar.
