Nancy, here’s a question for you. Should my calorie intake fluctuate based on how much training I'm doing?  I usually do between 90 and 120 minutes a day, but sometimes I might do just a 45-minute workout.  Do I cut my calorie count proportionally?

 

Answer:

On days when you are doing less exercise you will likely want to eat just as much (or almost as much) because—

 

1) Your muscles are using any extra unburned calories to refuel your depleted glycogen stores from the previous days’ tiring workouts, and

 

2) You may be more active during the rest of your "light exercise" days. That is, observe if on your light days or rest days you decide to mow the lawn, vacuum the house, wash your car, and do lots of errands. That extra activity counts!

 

Your best bet is to listen to your body; it is your best calorie counter. If you are thinking about food and fighting the urge to eat, your body is saying it needs more fuel. When you eat something to resolve that hunger, observe if you--

--feel better,

--stop obsessing about food, and

--have interest in doing something other than fight off urges to eat.

 

I generally eat just as much on rest days. Sometimes by dinner I am not as hungry, so I eat a lighter dinner just because I don't want a heavy meal. I listen to my body and trust it can regulate an appropriate food intake. Perhaps you can experiment and observe ithat your body can also naturally regulate a proper intake? (It that seems too hard, you might want to meet with a sports dietitian who can help you eat intuitively. Use the referral network at www.SCANdpg.org.)
