The myth of energy balance – simply stated:
Energy in (E+) minus Energy out (E-) = Change in Body Fat Stores
The myth states: the same amount of ENERGY IN (calories consumed) and ENERGY OUT (calories burned) over time = body weight stays the same. More IN than OUT over time = weight gain. More OUT than IN over time = weight loss. On the surface, this sounds like common sense. But it’s not true. This oversimplification exploits a false assumption. We are not what we eat, we are what we metabolize. See https://hypoglycemia.org/energy-balance-debunk/ for a more complete answer.
