Refeed is a period of increased calories. Whenever I do this I ensrue that calories are set back to a baseline (otherwise know as maintenance calories) as the individual is usually in a calorie deficit prior to this.
The idea is to give the body a break from being in a calorie deficit from anywhere from 1 day to 3-4 days. This helps offset any negative adaptations of being in a calorie deficit and ensure continued fat loss when the individual goes back into a calorie deficit. The increased calories to baseline should primarily come in the form of carbohydrates to load glycogen storage levels.
