Fat can break down into ketones which can be passed out via urine (i.e. leave the body without being oxidized to H2O and CO2).

This is noted in the article, in the caption under the second figure.

There is a hard limit of ketogenesis: about 185g of ketone bodies per day [0].

(That's about 2 lbs every 3 days).

That's a matter of liver health, right? So you could theoretically go higher (by combining antidiabetic drugs with beta-adrenergic agonists, and then sitting in a hospital in a cold water bath hooked up to a liver dialysis machine.)

Not a viable alternative to dieting and exercise, of course, but maybe an alternative to liposuction or gastric-bypass surgery.
