I have been considering whether to jump on this particular bandwagon, but so far there is no evidence provided that supports forcing that amount of protein at that time.
I agree that there's plenty of evidence from other sites that increasing protein and fat (not necessarily in that order) will help with leptin sensitivity. However, I thought that the 'eat breakfast' argument had been pretty well debunked in terms of its role in metabolism. I guess if I was heading off to do surgery all day, or to some other job that meant high concentration, high stamina and limited access to good food then I'd eat like that first thing. In fact, if I'm heading into that kind of day, I do force a good breakfast. But I'm spending my day marking essays within an easy walk of my own kitchen. Why would I stuff myself with food that my body is going to struggle to digest today??
This from the comments section of part 3:
"Why do you want to rise and eat that protein so quick? The food effects the gut’s incretin system to stimulate PYY which immediately sends messages to the hypothalamus that you just ate high quality chow and we don’t need to eat again for a while. So it in essence it shuts of all hunger signals (arcuate nucleus) and craving signals (NPY). It also helps shut off morning cortisol which sensitizes the liver to perform when fuel stores do get lower later…….in english this means you can go longer on the food you ate with out feeding again. Your liver is able to distribute its stored calories when you need them……and this ultimately results in less calories eaten and you have no hunger or cravings to boot. This sounds like an obese persons dream but I can tell you this is precisely the mechanism of how a paleolithic diet works to shred fat and weight. The more protein and fat you eat the less calories your brain will crave and drive your behavior to graze. Next real bonus then occurs……this allows you to stretch your meals sometimes to once or twice a day. When you eat a calorie reduced diet without hunger or cravings……this is called intermittent fasting (IF). We are biologically wired for this because in paleo times we did not have 24/7 access to Costco’s. And IF increases a cellular process called autophagy that increases our lifespan by recycling our cells and keeping our cardiac stem cells from being used up! Moreover, eating meat early in AM (bacon) provides us with a nutrient called carnosine which has also been shown to increase our telomere length. Anything that increases our telomere length increases our survival too. This is the great circle of life. Paleo is not a faileo diet. Eat meat and eat it as soon as you rise. Im very strict about my timing of meals……the food itself just needs to follow paleo dietary pillars. you mentioned your heart……….IF stimulates autophagy to save your heart cells from getting taken out! The Circle of life is now complete"
How is this argument any different from the paleo argument? I'd really like to hear from people who followed the science and found this change (to large amounts of protein first thing in the morning) to be compelling. I just don't at this point.
