Jay Feldman is back for his fourth appearance on B.rad!
Jay is one of my favorite guests to have on the podcast and our episodes together are some of my all-time favorites, as I love the way he presents his compelling argument that we should rethink many of the foundational principles of ancestral health, such as intermittent fasting, low-carb, keto, and time-restricted feeding.
You will hear some scientific insights in this show that will get your head spinning and inspire you to rethink many of these practices we’ve been indoctrinated into from a big-picture perspective, such as are these things we’ve been doing actually healthy? And who (and what) can we trust to lead us down the path towards a healthy, happy, balanced, and energetic life? As you will hear in this show, a lot of the science and dogma we have been fed for a long time (not just mainstream dogma, but ancestral dogma as well) can now be scrutinized as coming from flawed or dated science or misinterpreted science. We talk about a few controversial topics, such as the comparison between being a fat burner like our ancestors or prioritizing carbohydrates as the human body’s preferred and most efficient source of energy, and you’ll also hear about the actual causes of excess body fat and how to get it off appropriately and healthily. Finally, we wrap up with a round of quick questions: are Omega-3’s really the anti-inflammatory Kings/vaunted centerpiece of our diets, or should we now avoid all forms of polyunsaturated fats?  
 
TIMESTAMPS:
We need to rethink many of the foundational principles of ancestral health. [02:35]
There is much controversy among extreme health enthusiasts regarding healthy nutrition. Compare being a fat burner versus being good at burning glucose. [08:21]
We must question and be open to learning new things.  In school we are taught to read this book and memorize what is in it. You have to experiment on your own for what is best for you.  [10:11]
What people are the best candidates to thrive on keto, fasting, or carb restriction? [16:43]
Stress can catch up to you when you are involved in some of these restrictive diets. [20:56]
Fructose can go to the liver and cause fat, but there is much more to it than that.  [22:17]
What is going on when the hunger is dysregulated and the obesity is occurring? [30:58]
When Jay was a young athlete, he was experimenting with his diet and at one point was emphasizing starches and doing himself a disservice. [32:33]
Let’s talk about sugar. Good or bad? Ray Peat’s work talks about preferring carbs over fats. [38:25]
Our health depends on our ability to produce energy. [43:43]
When we look at our evolution from our ancestors, we see that if we are in an environment that is more energetically favorable, it’ll lead to greater complexity, greater brain function, greater ability to function. [45:52]
Calorie restriction is not the best way to extend life span, according to Jay. [55:20]
Work on not being sedentary and work on changing the foods you eat. [01:01:05]
It’s fats versus carbs?  Which is better? You don’t have to put all your eggs in one basket. [01:04:17]
Fat burning produces more reactive oxygen species and as such, it has a hormetic effect. [01:08:23]
Keto, fasting, those things are beneficial in some ways despite the stress. [01:16:47]
If getting fat adapted is known to have a performance benefit, is this a different paradigm than us at rest and trying to get through our life when we're going out on a four-hour bike [01:24:20]
What about mixing carbs and fasts in general? [01:27:57]
If you are carrying excess body fat, it is important to get healthy first by making better choices. [01:32:10]
Does prescription medication have an influence on things like our hunger, satiety, energy production signals in terms of side effects? [01:33:45]
