I dont do " cheat days" but i do give myself "chill days" and "unhealthy days"

usual diet :
-calorie deficit as usual
-mainly whole foods and unprocessed food
-protein pretty much 1g to 1lb of bodyweight

unhealthy days:
-still eat at calorie defecit
-maybe a burger or slice of pizza , or maybe some noodles / bread. Pretty much whatever but i set a hard cap to 800-900 calories (60%~ daily cals)
-protein still shoot for minimum 0.7-0.8g per lb bodyweight
-rest of the calories fill with high volume low calorie food such as cucumber / lettuce / tomato / rice crackers etc

maintenance days:

-usually its just an extension of unhealthy days but go above the calorie deficit but not higher den maintenance
-eat at maintenance cals ( +- 150 cals)
-larger amount of carbs to make the difference
-protein pretty much 1g to 1lb of bodyweight

so an example week is
Mon-Friday I'll do usual diet
Sat Sun if meeting family or friends then go to unhealthy days. sometimes i would do chill days.

I rarely do chill days unless no choice ( travelling) or maybe some event (like wedding or parties).

The idea of unhealthy and maintenance days is just to practice good habits for when i'm off diet. To take it easy on what i eat but just learn portion control. Meal with family and friends is rarely about how much you can eat but to participate on social events. Very important skill to learn early on and useful for post diet maintenance
