In this episode of A Whole New Level, Christopher Gardner, PhD, joins Mike to discuss his decades in nutrition research, the challenges of conducting randomized controlled trials (RCTs) on diet, and how to communicate complex science to the public. Gardner has led some of the most rigorous research ever comparing dietary approaches in real-world conditions, so his insights about what works (cutting processed food and sugar) and what doesn’t (obsessing about macronutrients) are worth a listen.

In this episode of A Whole New Level, Dr. Eric Ravussin, PhD, explains the physiology of energy expenditure, metabolic adaptation, and why the body strongly defends its prior weight. Drawing on decades of research, including the Biggest Loser study, CALERIE, and work with metabolic chambers, Ravussin walks through what actually happens when we lose weight—and why willpower alone isn’t enough.

According to investigative science journalist Gary Taubes, much of what we “know” about nutrition is built on weak evidence, bad assumptions, and decades of groupthink. In this episode of A Whole New Level, Taubes joins Mike Haney to examine how nutrition science went off the rails—and why he remains convinced the carbohydrate–insulin model still offers the most coherent explanation for obesity. Taubes explains how observational studies became policy, why randomized trials are often ignored, and why questioning the calorie-balance model remains controversial despite mounting contradictions. The conversation is less about winning an argument and more about how science should actually work—especially when public health is at stake. ⁠Sign Up to Get Your Free Ultimate Guide to Glucose: ⁠⁠https://levels.link/wnl⁠⁠⁠ 🎙 What Gary Taubes & Mike Haney discuss: [4:10] — How Gary Taubes became interested in “bad science.” [9:45] — Why nutrition science relies too heavily on epidemiology [15:30] — Correlation vs. causation in diet research [22:10] — The problem with the calorie-balance model [29:40] — Introducing the carbohydrate–insulin model [36:55] — Why insulin resistance changes everything [44:20] — Why low-fat advice dominated for decades [52:10] — What randomized trials actually show [1:00:05] — Why dissent is treated as heresy in nutrition [1:08:30] — How bad science survives criticism [1:16:45] — What good nutrition science would require [1:23:20] — Why this debate still matters Levels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.

Hormones influence far more than reproduction—they shape energy, mood, metabolism, sleep, and long-term health. In this episode of A Whole New Level, Dr. Anjali D’Souza joins Mike Haney to explain how women’s hormones actually work, why so many symptoms are dismissed as “normal,” and how to interpret labs in a way that reflects real physiology. They discuss why standard hormone panels often miss functional problems, how nutrient status and lifestyle affect hormone signaling, and how symptoms like PMS, fatigue, and brain fog provide meaningful data—not noise.

In this episode, Dr. Jesse Mills, Director of the UCLA Men’s Clinic, joins Mike Haney to explain what’s driving that shift and what today’s data-driven approach to men’s health looks like. He breaks down the testosterone “revolution,” what’s really happening in low-T diagnoses, and how lifestyle, sleep, and stress management can influence hormones as much as prescriptions can. They discuss: - How men’s health became its own medical discipline - What testosterone really does—and how to know if it’s low - Primary vs. secondary hypogonadism and how to tell the difference - When testosterone replacement is appropriate (and when it’s not) - Why younger men are now embracing prevention and optimization And listen to Dr. Mills’ new podcast, The Male Room with Dr. Jesse Mills, wherever you get your podcasts.

If you want to improve your energy and long-term health, start by understanding how your body uses glucose. In this episode of A Whole New Level, Dr. Benjamin Bikman, scientist and author of Why We Get Sick, joins Mike Haney to unpack the science of glucose metabolism and insulin resistance—and why blood sugar isn’t the whole story. Dr. Bikman explains how insulin regulates energy balance, why HbA1c is only part of the picture, and how chronic high insulin can silently drive weight gain, fatigue, and metabolic disease. He also shares practical ways to lower insulin naturally through diet, exercise, and daily habits.
