It's time to bust the 'calories in, calories out' weight-loss myth

If "Calories in, Calories out" is a myth then the Law of Conservation of Energy is repealed.

Wheee! Let's all start making those mythical Perpetual Motion Machines!

Obviously, the human body is designed (evolved!) to run on as little energy as possible when food is scarce. It does that by reducing (NOT eliminating!) its energy requirements.

That's why reducing your food intake doesn't necessarily produce a loss in weight: As long as you're taking in more energy than your body's minimum energy requirement, you won't see any weight loss because your body's reduced energy requirement has kept pace with the reduction in energy available.

Articles like this just spend a lot of words explaining complexities, but neglecting to say: "... and that changes 'calories in'", or '... and that changes 'calories out'".

The article headline even said so: "more complex than at first glance". And every example they give does nothing more than adjust calories in or out.

Is it way harder to calculate calories in/out than it would seem? Absolutely! But that does not make the statement false.

While there is a point with the "humans are bad at estimating calories" hasn't it been shown that most of the increased weight is because of excess calories. Like the metabolism is higher is heavier people, and various differences account for only miniscule differences in weight.(Barring rare extreme cases)

Not a myth. Not a myth at all.
