HELP! NET CALORIES IN THE NEGATIVES??!

Also to burn 655 calories you would need to be running at a fair speed for a good 2 hours or so. If you have just used the count on the treadmill (or whatever) it is bound to be way incorrect. Even MFP, Calorie King or Map My Fitness calorie counts are so far out of the field I am very wary of using them in case I overestimate my excersise calories. Maybe cross reference your calorie counts with other sites to see if you get a similar tally.

655 for two hours of running? For just how light of a person and at what speed? Mayo Clinic estimates 606 calories per hour for a 160 lb human at 5mph ... one of the lower estimates.

The math resulting in needing two hours of running to burn 655 calories is suspect.

lol. 655 cals burned in 2 hours of running at about 6mph for a hobbit child, MAYBE. and even then, it would have to be a very small hobbit child.

Yes, I am unfortunately a hobbit child

I ran 10km in 62:49 and burnt 344cals and that was running at between 10kph and 11.6kph for 9.5 of those kilometers. OP looks to be about my size 164/59kg ish. I am pretty fit and hobbity though with a low heart rate so that probably lowers my numbers unfortunately. Those calorie estimates are always based on what an average man will burn also, so pretty useless for women or anyone who falls outside the bell curve like us hobbits :sad:
