Cheat anything is bullshit.  Healthy is not one meal, it's a lifestyle.  I have this one friend who is normal sized, but always wants to lose 5-10 lbs and she does have 5-10 lbs to lose.  (I'd estimate her at 26% body fat)  She is always doing this and it makes me want to slap the shit out of her.  She will eat really "healthy" all day with NO protein or fat because she doesn't understand that fat is good for you, she focuses on calories. And guess what?  She's starving by the end of the day and then has a cheat meal. "Saying 'Oh, I’ve already ruined my good eating today. I’ll just eat crap,'  is like saying 'Oh, I dropped my phone on the floor. I’ll just smash it until it breaks.'"
