Let's go with the standard 3,500 calories to gain a pound of weight. Let us suppose that an individual's ability to accurately gauge daily caloric consumption is off by a mere fifty calories. Now, for a 2,000 calorie per diemm budget, that is a mere 2.5% error rate. Rather trivial, sounds like. But over a year, that adds up to a little over five pounds. Not even half a can of soda off and you gain five pounds a year, or fifty in a decade. The math matters, but does does the calibration and the ability to accurately estimate consumption. Even a tiny error amount means long-term weight gain. It's pretty easy to be glib about it. A fidgeter, someone who wiggles, bounces their feet, etc., can burn perhaps three hundred extra calories per day. You can also see how that adds up. The tiny increments matter little against time.
