In this “Ask Me Anything” (AMA) episode, Peter dives into two important health topics: uric acid and protein, examining them from unique perspectives. For uric acid, he explores its metabolic role and connection to various diseases, focusing on the potential causal link with cardiovascular disease. He also discusses factors influencing uric acid levels, such as diet, genetics, and lifestyle, providing practical tips for effective management. Shifting to protein, Peter delves into its role in appetite and weight management, the consequences of insufficient protein, and the “protein leverage hypothesis” linking protein deficiency to obesity. He covers optimal protein intake and its impact on energy expenditure, and he compares the satiety effects of solid versus liquid protein. Finally, Peter shares his strategy for incorporating protein into a comprehensive weight management plan.
