Another weight thing but perplexing to me. Every Saturday at 8 AM I go off on my club ride. We do anywhere from 40-60 mi. Usually at least 2500-4000 ft. of climbing and I burn at least 2,000 calories. Then I come home and during the rest of the day probably put 2,000 calories back into my body. Maybe a bit more but I don't pig out. The next morning I get on the scale and invariably my weight has gone up by 2 lbs. Just wondering if anyone has an idea why that happens.
