Tools for Nutrition & Fitness | Dr. Layne Norton

**Andrew Huberman** (0:00)
Welcome to the Huberman Lab podcast, where we discuss science and science-based tools for everyday life.
I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. My guest today is Dr. Layne Norton. Dr. Layne Norton did his training in biochemistry and nutritional sciences, and is one of the world's foremost experts in exercise and nutrition. He is also an expert in the topic of supplementation and other tools to augment health. Today, we discuss a large number of very important topics in these categories. And we start the conversation by establishing what Dr. Norton's thresholds are for what he accepts as evidence, in particular, actionable evidence. So what follows is a description of what Dr. Norton really believes is worth paying attention to versus what he believes is worth ignoring in the realms of nutrition, training, and supplementation. So you can be certain that as we start to go through the topics of sugar, GLP-1 agonists, things like Ozempic, artificial sweeteners, whether you should train to failure or not during your resistance training sessions, how much volume of training you need to do, cardiovascular training and its different forms in terms of how they benefit healthspan and lifespan and body composition, protein and its different sources, and on and on. Indeed, we cover many topics in this episode. You can be sure that all of the information you hear from Dr. Norton is being filtered through that extremely stringent filter that Dr. Norton is so well known for. And thus, by the end of today's episode, you'll be armed not only with the latest information on nutrition, training and supplementation, but you'll also be armed with your own filter to determine what sorts of health protocols are actionable for you. Before we begin, I'd like to emphasize that this podcast is separate from my teaching and research roles at Stanford. It is, however, part of my desire and effort to bring zero cost to consumer information about science and science related tools to the general public. In keeping with that theme, I'd like to thank the sponsors of today's podcast. Our first sponsor is Mateina. Mateina makes loose leaf and ready to drink yerba mate. Yerba mate has long been my preferred source of caffeine, not just because it tastes great and provides that stimulant effect that caffeine provides for focus and alertness, but it's other many benefits that are unique to yerba mate, such as regulating blood sugar, high antioxidant content, and it can improve digestion. And of course, I drink yerba mate because I simply love the taste. While there are a lot of different choices out there in terms of yerba mate drinks, my personal favorite is Mateina yerba mate because it's made with the highest quality organic ingredients and it has a very rich but clean taste. And given Mateina's great taste and commitment to quality, I recently became a part owner in the company and I've helped design some of their drink products. In particular, I love the taste of Mateina's canned zero sugar cold brew yerba mate, which has a slight taste of lemon and I personally helped develop that drink. I drink two cans of Mateina yerba mate cold brew in the morning and I often drink a third can in the early afternoon. If you'd like to try Mateina, you can go to drinkmateina.com/huberman. Right now, Mateina is offering a free one pound bag of loose leaf yerba mate tea and free shipping with the purchase of two cases of their cold brew yerba mate. Again, that's drinkmateina.com/huberman to get a free bag of yerba mate loose leaf tea and free shipping. You can also find Mateina at all Sun Life locations and Erawan locations. So please be sure to look for it both at Sun Life and at Erawan. Today's episode is also brought to us by Eight Sleep. Eight Sleep makes smart mattress covers with cooling, heating and sleep tracking capacity. Now, I've spoken many times before on this podcast about the critical need for us to get adequate amounts of quality sleep each night. One of the best ways to ensure a great night's sleep is to control the temperature of your sleeping environment. And that's because in order to fall and stay deeply asleep, your body temperature actually has to drop by about one to three degrees. And in order to wake up feeling refreshed and energized, your body temperature actually has to increase by about one to three degrees. Eight Sleep makes it incredibly easy to control the temperature of your sleeping environment by allowing you to program the temperature of your mattress cover at the beginning, middle and end of the night. I've been sleeping on an Eight Sleep mattress cover for well over three years now, and it has completely transformed my sleep for the better. Eight Sleep recently launched their newest generation pod cover, the Pod 4 Ultra. The Pod 4 Ultra has improved cooling and heating capacity, higher fidelity sleep tracking technology, and it also has snoring detection that remarkably will automatically lift your head a few degrees to improve your airflow and stop your snoring. If you'd like to try an Eight Sleep mattress cover, you can go to eightsleep.com/huberman to save $350 off their Pod 4 Ultra. Eight Sleep currently ships to the USA, Canada, UK, select countries in the EU and Australia. Again, that's eightsleep.com/huberman. Today's episode is also brought to us by Maui Nui Venison. Maui Nui Venison is the most nutrient dense and delicious red meat available. I've spoken before on this podcast about the fact that most of us should be seeking to get about one gram of quality protein per pound of body weight every day. That protein provides critical building blocks for things like muscle repair and synthesis, but also promotes overall health given the importance of muscle as an organ. Eating enough quality protein each day is also a terrific way to stave off hunger. One of the key things, however, is to make sure that you're getting enough quality protein without ingesting excess calories. Maui Nui Venison has an extremely high quality protein to calorie ratio, such that getting that one gram of protein per pound of body weight is both easy and doesn't cause you to ingest an excess amount of calories. Also, Maui Nui Venison is absolutely delicious. They have venison steaks, ground venison and venison bone broth. I personally like and eat all of those. In fact, I probably eat a Maui Nui Venison burger pretty much every day. And occasionally I'll swap that for a Maui Nui steak. And if you're traveling a lot or simply on the go, they have a very convenient Maui Nui Venison Jerky, which has 10 grams of quality protein per stick at just 55 calories. While Maui Nui offers the highest quality meat available, their supplies are limited. Responsible population management of the access deer on the island of Maui means that they will not go beyond harvest capacity. Signing up for a membership is therefore the best way to ensure access to their high quality meat. If you'd like to try Maui Nui venison, you can go to mauinuivenison.com/huberman to get 20% off your membership or first order. Again, that's mauinuivenison.com/huberman.
