  1. If I am in equilibrium, consuming approximately what I burn, and then
    one day consume 10,000 calories extra, how much of that will be stored
    as fat? Anecdotal evidence says very little, but if I increase my
    calories by 500 per day over time I will begin to add one pound per week.

    My question is how much of a spike in eating is absorbed versus a steady
    and consistent increase over burned.

    Thanks Dave

  2. If you are inactive I'm guessing your body takes about 3,000 calories a day to
    get by. And a pound of blubber is 3,500 calories. Sounds like that if you take
    in 10,000 calories you will pack on 2 more pounds of fat --likely going
    straight to your burgeoning belly. And hard as unholy HELL to get off there,
    once it attaches.

    Nope, the calorie/pound of fats formula only works in reverse direction.
    That is, *if you are in deficit*, you will burn your fat at a rate of 3500
    calories per pound, until you meet your daily needs. But, if you're in
    excedent, you don't convert excess calories at 100% efficiency.
    First, extra calories are available as different kind of nutriments, and
    they have to be converted to the proper form before getting stored. There is
    quite a bit of lost energy when metabolizing proteins and carbs into fats.
    Actually, even dietary fats do not convert to storage fats with 100%
    efficiency. So, out of these 7000 extra calories, quite a bit will be wasted
    in the process of metabolizing them for storage.
    Second, digestion burns energy. And it burns energy in proportion to the
    amount of food to process. Around 10% of the energy is burnt as part of
    digestion, though it probably doesn't scale when you go into extremes like
    this one. Depending on what form these 10000 calories are in, processing
    them might be quite wasteful.
    Third, it is quite possible that the digestive system cannot cope with a
    huge amount of food. Some of it might just not get digested. Especially if
    these 10000 come from a binge, where food is often swallowed in large
    unchewed chunks.
    Finally, not all people are equal when it comes to handling extra calories.
    The Sims experience (overfeeding inates) showed that on such a diet (IIRC,
    they were fed 10000 calories/day), most people gain weight much slower than
    what would be expected from straight maths. Those who gain very fast often
    come from famillies with obesity, or are themselves already overweight.

    Short answer: it depends on your genetics.

  4. Thanks, this helps tremendously.

    In summation;
    Pour 7000 extra calories into your body;
    As confectionary sugar = X retained.
    As a hunk of poorly chewed rare beef = X - Y retained.

    (Y being energy required to process protein and inability to process
    unchewed food.)

    I am training for the Marine Corp Marathon in Late October and I have
    been bumping up mileage and food consumption. I have put on weight from
    my lows but not really lost any speed or endurance. I believe the weight
    is showing up in more muscle mass with a little stored fat. Which I
    think is fine considering how hard it is to add muscle and shed fat
    while maintaining calories.

    I need to consume enough calories to increase muscle while shedding fat
    to meet my goals and sometimes my body craves excess food, usually every
    three or so days and I take that as a sign to feed it without focus on
    structured diet. BTW I do not eat 10,000 calories on ANY day. My example
    is usually I add 1000 to 2000 calories to a 2300-2600 calorie diet @
    5-11 and 197 LBS age 43. This usually occurs the next day after a long run.

    Thanks again. Dave

    You do need some enzymes to break up saccharose. Whether your body is able
    to produce enough enzymes to process 1.750kg of sugar is a good question...
    Besides, it's not only a matter of enzymes, you will also have to "wet" it
    enough for enzymes to work, and then enzymes will have a hard time diffusing
    through the blob of sugar. It's quite possible that X will not be as high as
    expected. Though eating that much sugar in one go, even if half of it
    doesn't process, will test very quickly if you have any diabetic tendency...
    Even if you're not diabetic in the least, I hope this is only for the sack
    of illustration 😉

    Do you need that much muscles for a marathon? Many long distance runners
    seem to be rather on the light side...

    Don't believe, get a scale with body fat% or have someone use callipers on
    you 😉 If you're training for near-pro stuff, that's something you should do
    anyway...

    Well the best way to tell is to keep checking the scale and your body fat.
    Did you ever have any problem with weight gain or needed to go on a weight
    loss diet? If you don't, it's quite possible that your body is sending you
    the proper signal that you must feed it. If, as you say, you are running a
    lot and building muscle, it's pretty hard to guess your specific needs, but
    they might be quite high. Each metabolism is different... Again, the only
    way to know for sure is to keep track of your net fat weight. If it's
    remaining fairly constant, it means that you can trust your body to adjust
    your hunger for its needs.

    Yes, just an extreme example to help make a point!

    While I am not trying to bulk up, I want to minimze my % of body fat.

    Got one and am currently 19 - 20 %, which i think is too high for a
    marathon. Of course it is down from 30% @ 247 LBS in February, so i am
    happy but not to my goal yet.

    Yep, the body is amazing if you listen to it. Thanks again. Dave
