Exactly. Back when I lived in Texas, I was a budding small fat (borderline overweight to overweight category). Before I opened my eyes to the disgusting truth of the fatties. I had a friend(see: backstabber) who was at least four inches taller than me, purported lacto-ovo vegetarian / celiac who was definitely obese.  My eating habits at the time were certainly unstable and unregulated compared to how they are now, but whenever I would hang out with this friend, she and I would end up grazing the ENTIRE time.  Froyo!  Fancy cheese and wine!  More snacks! Full sugar soda! Gluten free baked goods!  Chips and dips!  Then her boyfriend would come home from his job and have Chipotle (he worked there) and we'd eat MORE.  It was absurd.  Absolutely mind-boggling how much a person can eat when they aren't paying attention.  I'd always go home feeling wretched and sickly.  It was no wonder she would rarely want to hang out- catching up on "lost sleep" all the time (she didn't have a job, and was going to ONE certification class) if you're fueling yourself with garbage all of the time, and not actually eating VEGETABLES (remember the vegetarian bit? I rarely saw anything other than chips at her house)  or anything good for her body.  I think back to how I felt when I was overweight, and I cannot believe the difference in my overall eating habits as well as my energy levels.
