There could be a difference between absolute fasting and partial fasting. Partial fasting, intermittent, the wiser method, is longer term, but the first time sugar is eaten, insulin kicks in, and rapid weight loss resets back to moderate.
Then it takes 1 to 3 days to kick back into more rapid. Keytone strips that test urine, clearly show a big diffence between 1 day vs 3 or 4 day fasting.
Yea, I don’t know what to make of it, other than a possible miscommunication. Obviously I agree that the first few days of fasting results in a very quick weight loss. In fact, for me, if I eat (a lot) for dinner Monday and then start fasting, weigh myself Tuesday morning, and then Wednesday morning, I’ll drop 4.5 pounds in that one day interval. I figure most of it is the food getting further processed in my tummy, which requires a bunch of water.
But for long term, starting after 2 days of fasting I hit that 0.67 pound per day rate, and hold at that level (although with ups and downs...but the average always holds).
Anyway, no big deal, just don’t get hopes too high regarding the speed of weight loss from fasting alone. Even so, fasting is great for health, and it certainly works for weight loss! After all, it HAS to work for weight loss.
