Not too concerned about my own weight, but what i have read is when you exercise you speed up your metabolism. So the furnace wants more wood to burn whether you exercise that day or not. So it's really tricky because you feel hungry. The book I just read "Younger Next Year" suggests you exercise EVERY DAY.. then you can moderate your intake better. If you ride (like I do)
2 hours one day, 4 the next and not ride 5 days in a row, the food management gets harder. I get SOOOOO hungry every day, it's annoying.
