I'm reading a lot of conflicting information online on this topic.
Proponents of cheat days say they are great for providing some relief from some of the adverse hormonal consequences of calorie restriction such as slower metabolism, lower thyroid hormones etc. as well as having psychological benefits such as reducing the sense of deprivation from prolonged dieting and allowing you to attend social gatherings where eating clean is near impossible.
But most of the mechanisms behind successful dieting rely on eating clean (to reduce inflammation) and restricting carbs to some degree (to lower insulin resistance and help the body shift from burning carbs for energy to burning fat) and weekly insults might therefore be enough to throw you out of a fat adapted state and spike blood sugar and insulin levels and inflammation and the damaging effects can therefore extend beyond the single cheat day and spill over into the rest of the week. So a weekly insult over time can still do a lot of damage. Especially if you are treating the cheat days like a Man vs Food episode.
Obviously no one can eat perfectly 100% of the time because life gets in the way and sometimes cravings are just too strong to overcome. But cheat days involve deliberately scheduling unhealthy eating once a week with the notion that one day a week eating unhealthily won't hurt and might even help.
