Refeed days explained: do they actually help a diet?
A refeed day is a deliberate, planned tool — not just a nicer name for a cheat day.
What a refeed actually does
A refeed day means deliberately raising calories — usually via carbohydrate — back up to roughly maintenance for a day or two during an extended deficit. This partially restores depleted glycogen stores, can modestly and temporarily support hormones affected by sustained dieting (like leptin), and gives a mental break from restriction.[1]
How it differs from a cheat day
Unlike an unplanned cheat day, a refeed is calculated — raising calories to a specific target (often via carbs specifically, keeping protein and fat closer to normal) rather than eating without a plan. It's most useful for people in a long, aggressive deficit (physique competitors, extended cuts) rather than someone in a short, moderate deficit, where the physiological benefit is smaller relative to the risk of it turning into an unplanned surplus.
