A recent study confirmed what I feel our communal common sense has known for quite a while. Women who exercise regularly have a better chance of staying slim even if they indulge in a fatty diet for a few days.
It generally takes the body quite a few days to adjust to an increase of fat intake. But women who regularly burned 150 - 300 calories were able to convert the excess fat into energy more quickly than those who didn't.
So what does this really mean. If you do a regular cardio workout, having a day of indulgence is a lot less likely to impact your waistline. Just another reason to have an exercise schedule and to stick to it.
I run just so I can eat homemade cookies. How about you?
