Out of curiosity, I went back and added up approximately how many calories I consumed today--every last morsel I put into my mouth--versus how many calories I burned. Here's the result:
Slice of whole grain toast with almond butter (210)
Protein shake (140)
Medium Peach (60)
Cup of Chai (100)
Medium Salad with 1 T olive oil (300)
Dried Fruit (100)
Dark chocolate covered almonds (220)
Added together, that's about 1930 calories. Not bad at all if all I did today was exist: the recommended number of calories for a woman of my age and weight is about 2000 daily.
However, I did more than just breathe and walk from point A to B: I went for a 25 mile bike ride (calories burned: about 1460) and a 2500 meter swim (calories burned: about 1000) for a total of 2460 extra calories burned.
If I were to replace the calories burned, so that my input would be equal to my output, then I probably should have consumed 4460 calories today--so I'm about 2530 calories short! No wonder I felt like el crap-o after my swim.
Now, I'm busily (and happily) trying to make up for lost calories with a serving of a pasta casserole for dinner, and a side of tortilla chips with melted cheese (one of my favorite indulgences). Next up: ice cream for dessert (of course).
I'm feeling better already! :)
