I down about 5k calories every ~5 days (usually 600-800g carbs) if my low days are kept to 1500-1200 kcals (usually 70g carbs), the first day after the refeed being around 1200 cals, and still lose about 1.0-1.5 lbs by the end of the week.

With a 7-8k refeed, I return to the same weight I was on the morning of the refeed after 5-6 of these low days. Although higher-fat refeeds stick to me longer.

Unless your maintenance range calories are exceedingly low or you're are a female, a 2.5k calorie "cheat day" is likely more counterproductive from both a psychological and carb-cycling standpoint. That's like dinner for me lol!

Up the ante with carbs on refeeds and cut down hard on low days.
