6 foot 182, 2300 calories workout days, 2100 non workout days. Cardio every monring for 45 at 75% and twice on non workout days. I found that 2 weeks ago with a full out cheat day I lost 1 1/2 pounds the following week, with a 8-12 hour cheat of only fat free items I lose 2 1/2 and if I do not cheat or refeed I lose 3+. What are the "losing too fast" parameters", are their any. I had a 10 hour fat free binge this past Satruday and today "Monday" I feel tto flat and not pumped like the days after the full blown cheat day.
