Super Size Me blamed fast food for obesity epidemic, sparked response docs — Solid (80/100)
Yeah, Supersize Me did blow up the fast food panic — and yeah, counter-docs like 'Me at McD's' proved you can eat junk and not explode. Solid setup.
Childhood obesity rising, fast food marketing to kids is huge cause — Verified (90/100)

Insane but checks out — 5k+ calories/day = ~1.5 lbs/day gain. Pure excess fueling the stunt 🔥📈

Day 14: developed food addiction signs — Sketchy (35/100)
Self-reported shakes/cravings = addiction? That's film drama, not clinical diagnosis 🚩🍟
