Assume you rode 50 miles in the day time and had nothing to eat all day.
Then you sat down at 7pm to eat a meal. Would the food turn to fat?

It might if it was a righteous helping of my sawmill gravy stroganoff.

Depending on what you eat and how long before you riding you ate,
here's what can happen. You eat breakfast. Sugar is released into your
bloodstream. Pancreas produces insulin to take care of the sugar. You
begin excercise right as you get into the insulin-induced low-sugar
funk. You feel like you're dragging.

^^^^^^^^^^^^^^^^
Your body is like a bank account, except that the transactions are in
calories, not dollars. If you rode 50 miles during the day without eating,
your body would deplete the stored sugar it had available, and then start
burning fat. The at the 7 pm meal, it would convert the food to sugar, and
distribute it to the bloodstream, muscles, etc. If you are healthy, none of
it goes out in your urine--any excess is stored AS FAT. Whether you gained
or lost weight on that particular day would depend on whether your evening
meal put back enough calories to replace what was used up.

that's not exactly true. It would depend on how your ride as to whether
your sugar stores would be depleted. A long easy ride would tend to not
deplete sugar stores as fat would be eventually the fuel system used.

You do really think that fat would be laid down that very day? It takes
time for food to be digested and converted. It is likely that it will take
a several days of overeating before fat is really laid down.

But the point is that food doesn't turn to fat just because you eat it after
6pm as Bill suggested.

It is all going on at once: burning sugar, storing sugar, burning fat,
storing fat. Just the rates and the balance changes. It's kind of
like filling a bucket with a hole in it by periodicaly dumping in
glasses of water. while varying the size of the hole. There will be
transient variations in the level in the bucket from glassfull to
glassfull, and there will be an overall trend over longer periods of
time. The overall trend is what is most important if you don't want
your bucket to overflow.

Also, unfortunately for some, the gut is very efficient. Pretty much
everything you eat which isn't immediatly used gets stored away, and
it doesn't take days. Almost nothing usefull passes out the other end
if one is healthy.

Agreed!

I'm not sure I believe that. Unless you mean stored in your gut or
somewhere along the line.

Fiber passes out. And it slows down digestion, too.

Almost all the energy value of food gets absorbed in just a few hours.
There are really only two storage forms in your body, glycogen and
fat, and only a very small amount of glycogen is stored, the rest is
fat. Nothing gets stored in the gut. But, fat is quite energy-dense,
about 4000 calories per pound, so even if you are just watching tv,
you would have to eat about 6000 calories to gain a pound in a day.
Thats like 10 Big Macs and a can of Diet Coke.

I guess what I meant was that everything that can be absorbed is
absorbed. If you eat 10,000 calories a day you will absorb 10,000
calories a day, your gut doesnt adjust itself to your actuall needs,
it just absorbs everything you throw at it, morning noon or night.

Over the span of a day, I could eat 10 Big Macs - if someone paid me, that
is. 🙂

Well, I'm going to let it go...But my personal experience tells me that the
body doesn't work on the 'day' plan like that. I've eaten big on one day
and found I didn't need to eat hardy at all (if any) on the following day.
I think food will hang around longer when you overeat than it will if you
undereat. I think the body can only process so much food in a given time
frame. Your gut might absorb everything you throw at it, but it doesn't
have the capacity to absorb everything you *can* throw at it in a fixed
about of time. If you up activity, it can absorb faster, but that's limited
too.

When I was searching the web for this sort of information, I found a
web site by a doctor that cycles about cycling, nutrition, performance,
physiology, etc. It is at www.cptips.com. It goes into detail about
how the body uses fat and sugar during exercise.

Thanks for the link. That is a good primer on exercise physiology and
nutrition.
