Not if the jar pays you an interest rate. I'm being facetious. But my point is calories out will vary depending on calories in. You can eat 2000 calories of carbs 1 day and 2000 calories of protein the next... turns out your calories out will be higher when you eat protein because your metabolism increases. This isn't physics. This is nutrition. And its still not fully understood IMHO.
