Staying fit is an active process.     This lack of foresight is one of the things that annoys me about the fats. They say, "Wiley, you're skinny. You can eat whatever you want." or "Why do you exercise everyday, you're fit?      So stupid. Just the other day a coworker (that had her fupa cut off in south america last year and is back up to her pre-surgery weight) offered me candy. I declined by telling her that I didn't want to use up my calories on candy. I got the skinny comment, again, and I used the opportunity to explain TDEE and show her the app that shows what 200Kcal of different foods. She bought diet pills on her lunch break. Lost cause.
