A lesson I learnt came from a fitness guy I watched. He said, missing out one day happens. Shit happens. Missing out 2 days is a choice.
I couldn't go out yesterday cause a storm came through. So I did 2 times what I normally do. I don't know if the effects will pan out, but at least I can say I did not slouch. I am ~3lbs away from my desired weight.
Good comment.
It's also dangerous. If you eat too much today and try to offset it tomorrow by starving (overshooting), you're going to hurt your body if it becomes a habit. (A deficit larger than ~500kcal will decrease your muscle mass)
Rest is also important for recovery, if you need it. The fitter you are. The more you can do.
