So you had food prepared and with you, and just said “Fuck it, I want a Whopper.”? As long as you recognize that it was the wrong choice and wasn’t in line with your goals, at least it’s a teachable moment.
If you feel guilty after eating a cheat meal, take it as your subconscious telling you that either you cheat too often, your “clean eating” isn’t really dialed in, you’re not training hard enough, or some combo of those.
Wendler recently said: “I think about it like people bringing their own food to a 4th of July party or Xmas dinner (or whatever) - you eat perfect the other 363 days/year, squat, push a Prowler/run and a few hotdogs won’t ruin you.”
I think that’s a pretty solid approach in general.
