Get ready for a hard hitting, straight shooting, fearless free-thinking fitness leader that will blow your mind and challenge you to rethink many of the basic notions of fitness, diet, and healthy living.Dr. John is a longtime innovator and thought leader in the biomedical fitness scene, having invented the globally popular OsteoStrong training device to fight osteoporosis. His more recent fitness sensation is the X3Bar, which is revolutionizing the way people think about and perform strength training. His heavy resistance band with attached bar system allows you to work the range of motion with the highest power output (the end of the movement) with the highest resistance. This is the exact opposite of lifting a heavy bar, where you are constrained by the hardest part (e.g., lifting the bar off the floor) of the lift. You’ll hear Dr. John’s full explanation in the show, but essentially, you get a more challenging and complete workout in a much shorter time period.We also talk about Dr. John’s astonishing dietary strategy of eating just once every 48 hours, when he enjoys a full-bore carnivore feast. That’s right, Dr. John is maintaining his muscular, single digit body fat physique (6’0” and 240lbs) with a zero carb diet and a workout protocol of 10 minutes per day, 6 days a week! Yes indeed, this guy is off the beaten track by many miles and it’s incredibly refreshing to open your mind to greater possibilities, challenge bullshit conventional stupidity that’s been proven wrong over and over but we still blindly follow it, and listen to someone who is not afraid to speak his mind at every corner, and back up his seemingly crazy proclamations with extensive scientific research and knowledge base. “We are not meant to exert ourselves with that much intensity for very long,” Dr. John says, pointing out that while most people assume that a lack of motivation is the reason why people can’t go hard with a workout for more than ten minutes, it’s really a lack of glycogen! Meaning, it’s biological, not mental: if your body is screaming at you to stop, listen, and stop. Dr. John shares a story about how, during the last few sets of an hour-long workout he did, his ears started ringing. “I felt awful, so I thought: what is going on here?” Now, Dr. John is certain that this was his body sounding the alarm on what wasn’t working:  “This was my body’s way of saying: no, we are not doing this anymore!”  Finally, we wrap up with some great advice from his dad, a former NASA engineer: “Don’t think people are going down the right path. Look at the problem, and think of anything else that might address that problem than the way people are doing it, because there might be a better answer.”Enjoy this informative and surprising episode with Dr. John, and check out his new book, Weight Training Is A Waste Of Time.TIMESTAMPS:Brad’s guest today has made many innovations to the fitness culture. He calls out the BS in the fitness industry. [01:39]John makes some pretty strong statements regarding the information we have been given. Are calories important? He eats only one meal every 48 hours. [05:06]It has a lot to do with looking at what happens during fasting. [08:51]Some people, in an attempt to find a diet, try to find a solution that doesn’t require a change. [11:02]John compares the idea of the bears creating diabetes so they can hibernate with what the humans have dealt with. [14:10]Hydrating is another purpose of carbs. [18:59]You only need antioxidants if you are oxidizing. [21:28]What are oxalates? [22:31]John explains his 48-hour fasting theory. [25:22]The larger muscle becomes, the more blood it needs to function correctly. [28:21]The X Three Bar delivers results with weight changing as we move it. [33:00]What do we really want when we exercise? We want to change our bodies. [37:59]Why is this going to have less risk of muscle soreness and damage than doing sets with a heavy bar?
