I've recently started using www.fitday.com as suggested by a poster here or on RBR I forget which. I've noticed that I burn off way more calories than I intake on a daily basis. In the last couple of days I've eaten...
Day 1 Day 2
Eaten 3304 3179
Burned 4489 4501
Calories Missing 1185 1322
Is it okay to have this much missing a day? I don't feel adversely affected or anything but I don't want to be doing something to my body that is a no-no. Are these internet sites very accurate anyways? I know the data on what I'm eating is accurate but the burned data could be off. Thanks for any help.
