In this “Ask Me Anything” (AMA) episode, Peter addresses follow-up questions related to recent conversations around exercise, kidney function, and brain health. He begins with the topic of exercise, covering aspects such as starting rucking, transitioning from muscle building to maintenance, the optimal order of lifting weights and cardio, and exploring heart rate recovery. Shifting gears, he delves into the realm of kidney health, discussing the most effective blood tests to measure kidney function, desired levels, the natural decline with age, and the crucial role of maintaining a high glomerular filtration rate for longevity. Additionally, he discusses the importance of managing homocysteine levels and alcohol consumption for brain health.
