So, I really like to do endurance events, and I know that I am going to have to fuel myself differently after surgery.  Now, I just pop a GU or shot block and am on my merry way.  

How soon after surgery were you able to get back into sports, and how do you fuel yourself now?  Do you find yourself weary?

Yeah, if you're not burning a ton, I wouldn't worry about it. Just make sure to listen to your body.  It will tell you, very loudly, if you need more.   

For me, it depends on the level of exercise.  For example, last Saturday I ran 16 miles up a mountain and burned just under 2000 calories in 3+ hours.  I literally had to eat some of those back.  I try to stay around 1200 calories on normal or easy days, but on those hard days I pu**** up.  Makes recovery easier and makes me feel less like death.  So I guess if you're looking for a rule of thumb, mine is about this:  anything less than 500 calories burned, I ignore.  Above that, I eat a portion of back, as needed by listening to my body and knowing what it needs.

A big thing to remember is DO NOT trust calories burned calculators.  I barely trust my heart rate monitor, but it's probably accurate enough. 

Thanks Billmacc, I feel the same. My nutritionist encouraged me to eat more and to compensate for the calories burned. I am fearful to do so. Thanks for responding, Mike
