Will one cheat day ruin my progress?

ONE cheat day will not ruin your diet. It's only ruined if you have many cheat days and don't do anything to undo the calorie intake.

of course not. but in my own experience, once cheated, always cheated...I had one cheat meal, and didn't see any consequence, then I start thinking "oh I guess I can do one more time"...and you know the rest.

So the point is one doesn't matter, really only if you can stop after one.

It takes 3500 to gain a pound, eat less food than that you won't gain.

No...

It takes 3500 over your maintenance to gain a pound. Anything over your maintenance will cause you to gain, a real gain, not water weight, at least temporarily.

I was getting ready to say this too.
