From your numbers, self consumption of breast milk has a roughly neutral energy balance. Losses will come during the digestion process, so taking the whole thing, will be a net loss (as expected, in any case).Hmm. I'm not sure everyone is accurate. Looking at that, a woman could not survive on breast milk alone for very long. Anyone have anything to correct that, or any idea how to calculate the starvation point?
Digestion accounts for between 5 and 15% of the daily energetic consumption, depending on the diet. So, by not eating at all, the woman could shave her expenditure 1600 daily calories to roughly 1500. This will give her more time before the complete consumption of the sugar and fat reservoirs, after which the body begins to digest the muscle proteins (which end up producing organ failures which lead to death).
I have a question: can women stop cold turkey giving milk without experiencing health issues?
