Bullshit. This is 100% bullshit. If she is on ~1200/day she would be losing weight. That is how physics works. My advice is stop lying or tell your wife to stop

You would think so, but the "weight loss = calories in - calories out" is far too simplistic to describe the real world.

  No. It is exactly how to describe it. Energy in vs energy out.

    It ignores metabolism, there is evidence that the presence (or lack of) certain enzymes in the digestive system can drastically affect ability to absorb calories, etc. It is too simplistic to explain reality.
    - simplexion 11y ago
      It really is not.

        Just for fun, I'll paste my reply to another comment here: Do you genuinely believe that metabolism doesn't vary across individuals, or for an individual over time? Do you think the bodies of all individuals have precisely the same ability to both absorb calories from ingested food, as well as produce motion with the exact same efficiency? Do you believe enzymes present in the digestive system have absolutely no effect whatsoever on the calories in / calories out calculations? Do you think every calorie you put into your body is converted into energy? I'll add an extra one for you: in controlled lab tests, would all subjects lose weight precisely as predicted by a formula that considered their diet and physical activity?

It is when people are allowed to self report, the problems begin. Sure, everyone's caloric requirements are different, but everyone will lose weight if in caloric deficit. It is just the question of figuring out what will be deficit for this particular person.

        Do you need a subscription to read the full articles? For one thing, I'd like to read how they are measuring "energy in", are they subtracting calories in the subject's excrement?

        You're fat and in denial too, aren't you? Can't accept facts.
        mistermann 11y ago
        Actually I'm pretty much at my ideal weight, maybe a few pounds over. Which facts am I not accepting?

        Some articles are open access. In one case, for example, they used bomb calorimetry: Bomb calorimetry performed on eight batches ofsimilar formula prepared in the research kitchen of the Rockefeller University Hospital between April 1988 and July 1990 had a coefficient of variation for Id/g of 1 .9%. http://ajcn.nutrition.org/content/55/2/350.long http://ajcn.nutrition.org/content/55/2/350.long Again, I've seen little evidence of excreting unprocessed calories being a common case. And if we're looking at weight loss anyway, excreting some calories would even be an advantage.

      It is true that there are many factors that affect how a calorie is digested and stored, it is a complex system. But it is also true that there is no other source of energy for the body than mass. There is no metabolic process that can produce energy for more than a few seconds without a reaction that consumes mass (the carbon in said mass being breathed out as CO2).
