Basic dietary and lifestyle improvements, especially as they relate to snacking, are drastically easier to make when you don't have a decade's worth of bad habits holding you back. I wish I'd started cutting back on pops and energy drinks and chips and chocolate at 22 instead of waiting until I was 32 years old and pre-diabetic.

Also, fucking floss. It's not bullshit, and it's not a scam to help Big Dental sell you flavoured string. It's a real thing you should actually do. Especially if you're like me, still eating like a fucking teenager into your 30s.
