Someone who follows every food trend like it's a religion, even if they don’t need to lose weight or have a doctor’s approval.

I’m on the paleo diet now. I’ve been eating like a caveman for a month and I’m still not a caveman.

I tried the bulletproof coffee thing. Now I can't even drink normal coffee without feeling like I’ve been poisoned.

My coworker is doing the 16:8 diet and it’s driving me insane.
