There are three explanations I see:
- The DEXA data is wrong (either old or new or both)
- My RMR is wrong = I’m not running at 2700 cal/day.
- My Macro estimates are wrong = I’m refeeding at much more than 3000 calories a day
I went back and counted the days between the two DEXA scans. It was 22 days (tested Friday and Saturday) and I ate for 4 weekends of 3 days each.
22 days * 2700 cal / day - 12 days * X cal / day = 0 (no fat loss)
I realize the 2700 cal / day is not real, but it’s an average. So the average calories needed on a refeed day would have to be close to X ~ 5000 calories for that math to work.
That’s really difficult to imagine given the vegan + keto restriction… and hence why I hate calorie counting.
If I work it the other way and assume that my maximum calorie estimate of 3000 is right, then my metabolic rate would have to be a lot lower:
22 days * Y cal / day - 12 days * 3000 cal / day = 0 (no fat loss).
That would mean that my metabolic rate was Y ~ 1650 calories per day. Given that I was weightlifting, I would have had to be asleep the rest of the time to get there?
But frankly - that seems to be the only explanation. The fasting is reducing my metabolic rate down to where the 3000 calorie refeeds offset my caloric need.
So metabolism down to 1600 x 22 days, calorie intake on refeed at 3000 x 12 days = net zero fat loss.
Also - stress, sleep, and testosterone are probably not working in my favor reducing my metabolic rate and increasing my visceral fat. At this point, it seems that the cyclic fasting was a waste of time for fat loss - there are other benefits but not fat loss.
