Does anyone know how long it takes for any extra calories to move from your stomach to adipose tissue?
That is, how long after a meal can you be reasonably sure that it won't have any more of an affect on your visible body composition?

One meal will have zero effect on your visible body composition. It's probably mechanically impossible to eat/digest enough food to generate enough fat gain to visibly change your body composition in a period which one might consider a single meal; any reasonably eatable meal would not visibly impact you at all.
Visible body composition changes happen over time and in response to continued, sustained dietary/environmental stimuli. One day isn't even a blip. Think of it like a moving average and it's probably closer to the truth than "one meal == this much belly fat" model.

There is a constant movement in and out of adipose tissue.
Do a search on Loren Cordain's site. http://www.thepaleodiet.com/index.shtml He has some great research on this subject. Also see: http://ajpendo.physiology.org/cgi/content/abstract/266/3/E308
The main thing to worry about tho is that the main movement is out and not in.

That's going to depend on rate of digestion. As long as there is food in your stomach and intestines, then calories are being processed and moved into your blood stream. How fast they get processed also depends on how fast your body can digest them. Glucose digests quickly, even being absorbed via saliva. Usually protein and fat take longer but there are both slow and fast proteins. Many body builders like to use fast digesting proteins like whey to speed the protein to the body quickly. Overall, I'd say whole foods meals with mixed protein, fat and some carbs will probably take about 5 or 6 hours to digest. But results will vary from one individual to the next.
If you are overweight and trying to lose and are eating less calories than you are burning (and of course your body has not slowed down its burn rate and made you tired because you are on paleo), then probably most if not all of the time, the calories you are currently eating are not being stored in fat at all. THey are being burned.
However, if you are maintaining stable weight, then a majority of time during the day, you are probably actually storing some amount of fat in your fat cells. Because sleep is a time of fasting and so there will need to be extra calories stored in the day in order to feed your body in the middle of the night when all those stored calories will then be taken out of their storage bank and used. -Eva
