Dirty fasting is a type of time-restricted eating — like 12/12 or 18/16 — that allows you to consume about 100 calories during the fasting window.
At SIMPLE, we don’t subscribe to the concepts of either “clean” or “dirty” fasting because these words carry associations — of “cheating,” “permission,” or “guilt,” for instance — that aren’t helpful.
We’d simply consider eating more than 100 calories within your fasting window as breaking your fast and therefore interrupting the benefits of the fasting process. It’s not good or bad or wrong or right; it’s just a biological fact.
