Your body is NOT going to just "discard" (poop out) "un-needed" calories. Are you sure of that? I'll offer myself up as a datapoint. My weight is exactly (to the kg) the same as it was 12 years ago. I do not exercise, at all, and eat pretty much whatever I want, whenever I want (and that's a lot.) For comparison purposes, my sister-in-law runs a few miles every day, and consumes less than half the calories that I do-- and her weight has also remained constant for the past decade. Her incoming calorie-count is much less than mine, and her calories expended is much higher than mine. If my body does not discard un-needed calories, how is it that she's not losing weight, and I'm not gaining weight? (By the way: I worked for Ben & Jerry's for several years, and ate a pint of ice cream every single day. No weight gain, and only a marginal rise in my cholesterol count.)
