The 7 Pillars of Optimal Health: Nutrition — Your Diet Doesn't Need a Name
Keto. Carnivore. Vegan. Mediterranean. Low-carb. Low-fat. With so many competing opinions about nutrition, eating for health and longevity has become unnecessarily complicated.
In this episode of the Fit Rx Health & Wellness Podcast, Dr. Greg Dennis continues the 7 Pillars of Optimal Health series with Pillar #2: Nutrition.
After years of studying nutrition, longevity, and metabolic health—and seeing what works in clinical practice—Dr. Dennis shares how his own thinking about nutrition has evolved. Rather than following a diet with a particular name, he believes the foundation of good nutrition can be surprisingly simple: prioritize protein, eat mostly real whole foods, maintain a healthy body composition, and individualize carbohydrate and fat intake based on your metabolic health, activity level, and goals.
In this episode, you'll learn:
- Why calories still matter
- Why protein becomes increasingly important as we age
- The connection between muscle, metabolic health, and longevity
- Whether red meat belongs in a healthy diet
- Why healthy fats are beneficial—but aren't unlimited
- Why carbohydrates aren't necessarily the enemy
- The difference between whole-food carbohydrates and highly processed foods
- When low-carb and ketogenic diets may be useful therapeutic tools
- The pros and limitations of vegan, vegetarian, and carnivore diets
- Why ultra-processed foods may be a much bigger problem than any single macronutrient
- What Dr. Dennis actually eats and how his own approach to nutrition has changed over the years
The takeaway is simple: your diet doesn't need a name.
For most people, building meals around quality protein and minimally processed whole foods—while limiting the highly processed foods that dominate the modern diet—is a sustainable foundation for metabolic health, maintaining muscle, healthy aging, and longevity.
