Ah well, he actually does a decent review of cholesterol & heart disease.
He also seems to be something of a libertarian- regarding 'it's easy to eat too many calories' I think his opinion would be 'people know it's high-calorie food when they eat it, (he even does street-side interviews about this), and what with their being consenting, informed adults, changing their mind about it is none of our business'. (20 minutes in)
Further, the 5000-calorie thing is Spurlock literally stuffing himself. It's not so easy to hit that, as shown in the first half-hour. (15 minutes in)
'Addiction' was also one of the topics he rails against, to the point I even thought it was annoying. But I agree with him- No, it isn't addictive, that has a definition dude.
Which Strawman? (I'd not be surprised if there are several.)
He's pointing out BMI isn't a good measure, & the 'EPIDEMIC!' craze happened the same time the definition was changed. (44 minutes in)
Also, the documentary puts the cause of any BMI growth on our growing inactivity & what we eat between meals- snacks & high-fructose drinks. (28 minutes in) And also demographic changes. (48 minutes)
-Worth noting, one of my beefs with the documentary is right around that second spot. He claims minorities are genetically predisposed to being overweight. I'd need to cross-check that relationship with income-to-BMI before accepting it.
~50:00 is where it really starts to hit its stride.
