From weight loss and maintenance to the intricate relationship between nutrition and exercise and body composition, Peter addresses the complexities of nutrition research and explores the perennial question of whether there is a "best diet." He provides practical insights on how to choose the right diet for your unique needs, discusses the role of protein and processed foods, and outlines the key questions to help you optimize your approach to eating.</p> <p>If you're not a subscriber and are listening on a podcast player, you'll only be able to hear a preview of the AMA.

Actionable Insights
1. Prioritize Core Nutritional Elements
Focus your nutritional efforts on total energy consumption (calories), protein content, and essential minerals and nutrients, as the body is resilient and many other details may not significantly impact outcomes.
2. Ensure Minimum Fat Intake
It is important to hit certain minimums on fat intake to avoid severe malnutrition and related health problems.
3. Monitor Body Composition with DEXA
Utilize DEXA scans to measure lean mass, body fat, and visceral fat, as these anthropometric data provide a good readout of your nutritional status.
Monitor biomarkers related to metabolic health and glucose regulation, such as CGM performance, hemoglobin A1C, uric acid, liver function tests, and oral glucose tolerance tests, as they are important readouts of your nutritional status.
5. Test for Nutritional Deficiencies/Excesses
Measure for specific nutritional deficiencies, such as B12 in those who don’t eat meat, or excesses like mercury in individuals consuming a lot of large fish, using blood, urine, or hair tests.
6. Address Inflammation Through Diet
If you have unexplained inflammation, consider that it might be driven by nutrition; use empirical elimination and reintroduction of foods, like wheat, while monitoring inflammatory markers such as C-reactive protein or white blood cell count to identify intolerances.
7. Check Liver Fat with Scans
Consider getting scans of the liver to specifically look for liver fat, as this provides a fantastic and specific readout of your nutrition.
