As you can no doubt tell from the title, this is the updated version of Lyle McDonald’s Stubborn Fat Solution. Full review shortly (I’m about to dive in to it myself), but first a few words from Lyle on the reason for the update :
In the original Stubborn Fat Solution, I briefly discussed a hormone called Atrial Natriuretic Peptide (ANP). As I talked about, ANP represents an entirely new fat burning (lipolytic) pathway that works outside of the normal insulin/catecholamine mechanisms.
But at the time, I saw and knew of no meaningful way of manipulating or impacting the pathway and left it at that. A little while later I would find a solution and this booklet was actually started years ago; then I put it away.
Recently, in researching something else, I found that ANP appeared to be even more powerful than I had previously thought. Because in addition to stimulating fat mobilization, ANP (and the other natriuretic peptides) can also increase levels and activity of beige fat (a brown-fat like type of fat that humans actually have) along with helping to control appetite.
Lyle McDonald’s Stubborn Fat Solution 1.1. Good stuff.
