"A quick calculation. Assume you eat 30 g of sugar (C6H12O6), the contents
of one serving of fruit juice. That is 0.16 mol. Burning it into C6H12O6 +
6O2 -> 6CO2 + 6H2O produces one mol of carbon dioxide. That is 2.41 liters
of gas. How fast do you want to get rid of it? I think the device might be a
bit too embarrasing for macroscopic food intakes. "
Hmm, consider then how many kcal is 30g of sugar? How many liters of CO2
are exhaled with each breath? I figured such a device would be implanted
subcutaneously in areas where a lot of carbohydrates were stored, not in the
stomach itself. Since the full cell would process carbohydrates in the body
and not in the stomach, the excess CO2 concentration would be removed
through the normal process of removing CO2 after combustion, cellular
diffusion and exhalation.
