For keto in particular I'll agree out of ignorance. I was speaking broadly of "dieting makes social occasions hard" which is a common excuse to avoid certain diets. However, even with slower progress, I contend that slowed progress is still an improvement over no progress.
Very delayed follow-up, but I wanted to respond: you're 100% right.
Any progress at all is better than no progress. If being able to deal with social interactions by utilizing a cheat day helps stick to the diet -- helping to shutdown excuses, helping to be the "weekend" at the end of a long work week, etc -- then that's a useful model to adopt.
