If we're being pedantic, you'd need to eat 500 extra calories over your what your body burns daily.

But over a 6 year period, you would definitely accumulate 300 pounds of extra weight this way.

So the assumption here is that the pipeline for energy storage (including the human digestive system, insulin machinery and adipose tissue) converts calories to fat mass at a constant rate of efficiency, regardless of whether you're currently underweight, or at 350% of healthy bodyweight. Is there any human-built energy storage system that exhibits this type of performance? Do we really think that the human body exhibits it?
