Can I split up the calories earned from exercise?

Many people on here prefer to look at a weekly average. You can see how you're doing for the week on the reports. So yes, you can bank them for tomorrow, although I would recommend recording them all today.

I go over some days and am under on others, I look at how it averages over the week. Hasn't done me any harm yet :-)

Don't split up your exercise calories. Think of the children!

How many miles did you run? 600 sounds high

600 sounds entirely unrealistic. Probably more like 300.

echoing this...

OP, you should always do some kind of reasonableness test on your burn. 600 calories for 45 minutes is huge. When you're eating back exercise calories you want to be conservative...you want to make sure you are giving yourself enough fuel, but at the same time you don't want to overestimate. When I was doing this method I never logged more than 10 calories per minute for any activity...and 10 calories per minute was for a workout for which I could not hold a conversation.

With things like running and walking, 100 calories per mile is also a pretty conservative approach. Don't just take the database as gospel here.

Couple of ways of looking at this.

First, for a big workout (1000+ range), you want to eat back around half your calories unless you want to be a walking zombie the next day -- you just can't expect most bodies to be able to pull that number of calories out of your internal stores in that short of time.

For smaller workouts, I'm not sure why you'd want to eat back more than a small percentange, unless you're way more accurate about measuring your food portions and exercise calories than most folks. In my book, a 300 calorie workout is my buffer against sloppy food measurement.

That in-between range (roughly 300 to 1000) depends on the person -- a smaller person is going to have less internal short-term reserves than a big guy like myself. I'm sure I could easily burn 600, not eat it back, and not feel it the next day (OTOH, I tried to do that once with a 1200+ burn...didn't work out so well the next day).

Gotta agree about the folks crying "foul" on the 600 calorie 45 minute run...doggone difficult to to go over 10 calories / minute.

Yep. As others have said you can save them for the week. I exercise all week and save up around 900-1500 calories. Then on the weekend I let myself go over but track how much and make sure not to go over what I earned. It keeps this process from driving me insane because I get 1-2 days on the weekend that I can eat things I normally don't have the calories to eat (like pasta. I Pasta).

Forgot to add that I "reset" on monday morning. If I didn't eat my calories back by then, I don't get to. It is always better to be a little under than a little over on calories consumed.

I run with a heart rate monitor and a Garmin watch, which gave me the calorie burn -- ran 4.68 miles at an avg pace of 9:37/mile. I also weigh 175 so no, 600 calories is not ludicrous.

I only want to split the calories between two days. Thank you for those who replied to my question without having to question my calories burned

If you find you aren't losing weight, and it doesn't make sense per your journal, then worry about the calories.
