The reason for big protein breakfast, per Mastering Leptin
Since this keeps coming up, I went back to the Mastering Leptin book to see what's up.
The big protein breakfast is for this reason-
Metabolism can increase by 30% for as long as 12 hours from a high-protein meal, (the equivalent of a 3-4 mile jog).
A high carb breakfast does not increase metabolic rate. It may instead trigger a problem with insulin resistance.
High GI carbs shift your leptin release to earlier in the day, and you end up eating too much later, especially late at night.
The big protein breakfast helps get your metabolism going, stabilizes hypoglycemia for later, and helps prevent leptin fluctuations later in the day. Protein enhances release of glucagon, which mediates release of insulin...
from another section in the book-
For the first three hours after eating, your body refuels using insulin. You are not losing weight right then. You want this to settle down. Snacking disrupts it and fatigues the pancreas.
None of this is my opinion. All this is from Mastering Leptin by Byron and Mary Guignon Richards

Wow, another book to pick up. Thanks. I also see why Mark suggests omelets for breakfast

Thanks for posting this, man. Mad appreciated.
any mention on like a protein/fat breakdown? I have more time in the morning since switching jobs so I might start eating breakfast again. I'm pretty used to fasting, but I could never say no to meat at any time of the day. However, when they say "big protein" does that mean protein should be higher than fat? cus if so, buncha eggs prolly wouldn't do it right?
I would think the concern is more over avoiding carbs than fat. Though if you're just doing eggs, you need like 7-8 (large size) just to get the protein.

You want to wait long enough before you eat again for the body to switch over to burning stored fuel (fat) - so that as fat stores start to empty out, leptin levels will decrease, restoring leptin sensitivity.

It actually meant after waking, because your body does things when you wake up to fuel for the day, regardless of if you skipped breakfast. ML is saying that you want protein intake when that happens because of glucagon.
