Greg Mushen champions increasing your steps

Greg Mushen, the health researcher and systems thinker active on X (@gregmushen), has been shining a light on something beautifully simple yet powerful: walking. In his most recent podcast appearance—episode 662 of the Legendary Life Podcast with Ted Ryce, released February 16, 2026—he breaks down why consistent daily steps can play a huge role in supporting heart health, blood sugar balance, and overall vitality. He draws from real research on traditional populations and everyday science, keeping it practical and encouraging for anyone ready to build better habits.

Mushen shares how he shifted his own routine after a friend suggested aiming for at least 10,000 steps. He decided to push it higher: “I started doing it and I just noticed, you know, just this fat just coming off me. And I noticed just how much better I felt. And I still had a lot of energy in the gym for workouts because the fatigue was so low.” What started as a personal experiment opened his eyes to bigger patterns. He dove into studies on groups like the Tsimane in South America and the Maasai in Africa—people who live traditional, active lives. Their diets vary wildly (high-carb for one group, high-fat dairy and meat for the other), yet heart disease stays remarkably rare. The common thread? Movement. “They had a lot of varying diets… but one thing that was very common was the amount of steps that they took… and once that achieved two [PAL], you would see chronic disease just kind of vanish.”

PAL simply means Physical Activity Level—the ratio of all the energy you burn in a day compared to what you’d burn just resting. Hitting around 2.0 (roughly 15,000–18,000 steps plus daily life) appears to flip a switch for metabolic health in these groups. When people from those communities move to cities and drop their activity, risks like insulin resistance and high blood pressure start to creep in. The Amish community in the U.S. offers another real-world example: they average about 18,000 steps daily and show 30–40% lower rates of certain diseases compared to the general population.

Mushen explains the “how” in everyday terms. Walking helps your body handle the food you eat—something he calls nutrient partitioning and clearance. After a meal, blood sugar (glucose) rises naturally. A short walk gets special transporters in your muscles, called GLUT4, working to pull that sugar out of the bloodstream and into the muscles for fuel. “If you walk after a meal… a 50 minute walk in these type two diabetes patients was more effective than metformin alone,” he notes, referring to a common medication. It’s like giving your body an easy, built-in tool to keep levels steady without extra effort. Lipids (fats and cholesterol particles in the blood) work similarly—movement activates receptors that clear them out efficiently. You don’t need an intense session; consistent steps throughout the day do the job, though hitting a solid calorie burn through activity (around 800 or so across the day) can make a noticeable difference in triglyceride levels.

He introduces the idea of “flux”—basically matching what you take in (food and energy) with what you put out (daily movement). When output keeps pace, your body handles things better, even if your diet isn’t perfect. Genetics play a role too (some people carry variants like APOE4 that slow clearance by 15–20%, meaning they may need to watch saturated fat intake more closely or lean harder on movement), but Mushen stresses that daily walking is one of the most forgiving levers we have. It supports mitochondrial health (your cells’ energy factories), lowers inflammation, and costs very little in fatigue—making it sustainable long-term.

At Commit 250, we love how this fits right into building discipline through small, repeatable habits that add up. Walking isn’t flashy, but it’s accessible, free, and backed by real patterns across cultures and studies. It’s a foundational step anyone can take toward better physical and metabolic health—no extreme workouts required.
