    In this “Ask Me Anything” (AMA) episode, Peter delves into the often misunderstood concept of inflammation. He first defines inflammation and differentiates between acute inflammation and chronic inflammation, the latter of which is linked to aging and a plethora of age-related diseases. Peter breaks down the intricate relationship between chronic inflammation, obesity, and metabolic health, and highlights the signs that might suggest someone may be suffering from chronic inflammation. From there, the conversation centers on actionable advice and practical steps one can take to manage and minimize chronic inflammation. He explores how diet plays a crucial role, including the potential benefits of elimination diets, and he examines the impact of lifestyle factors such as exercise, sleep, and stress management. Additionally, he discusses the relevance of food inflammatory tests and concludes by examining the potential benefits and drawbacks of drugs and supplements in managing inflammation.

    In this special edition celebrating 300 episodes of The Drive, Peter discusses a variety of popular topics and health interventions and classifies them based on their level of evidence and relevance using the following categories: proven, promising, fuzzy, noise, and nonsense. Peter first delves into the topic of geroprotective molecules, covering rapamycin, metformin, NAD and its precursors, and resveratrol. Next, he explores the significance of metrics like VO2 max and muscle mass, as well as emerging concepts like blood flow restriction and stem cells. The conversation extends to nutrition, addressing questions surrounding long-term fasting, sugar consumption, sugar substitutes, and the contentious role of red meat in cancer. Peter not only provides his current stance on each topic—most of which have been covered in great detail in the previous 300 episodes—but also reflects on how his opinion may have evolved over the years.
