We always stress that tracking and measuring your biometrics is essential to successful biohacking, but sometimes you need to remember one simple thing: Listen to your body. Episode 39 features Ben Coomber, host of UK's #1 health & fitness podcast (Ben Coomber Radio) and writer for major publications such as Men's Fitness and The Daily Telegraph. A regular rugby player, Ben spends much of his time maximizing his athletic performance through the use of high-fidelity fitness, nutrition, and supplementation. As someone who dealt with childhood obesity and a multitude of other issues, Ben understands the difficulties of changing one's lifestyle even if they know it is for the better. While Ben has tinkered with various regimens and diets, he has concluded that his natural intuition is key to his own personalized health goals. Through educating and sharing his personal experiences to the world, Ben continues to push his audience to become a better, healthier version of themselves. Geoffrey Woo and Ben discuss the ins and outs of Ben's fitness and nutritional routine, the importance of recovery after training or working out, and the potential for exogenous ketones as a pathway to treat brain injuries.
