Dietary Macronutrient Focus: Carbohydrates vs. Protein
📌 The average American overconsumes total calories, with 50% of daily calories coming from carbohydrates, and 75% of Americans being overweight or obese.
🛑 The most dangerous macronutrient for the average sedentary person to overconsume is carbohydrates, primarily due to their impact on metabolism and insulin regulation.
📊 The average American consumes about 300 g of carbs daily, which is equivalent to having three oral glucose tolerance tests daily, distorting metabolism.
🧠 The brain and red blood cells require only about 80 to 100 grams of glucose daily (approximately 4 g per hour).
Carbohydrate Tolerance and Dosing
📌 For a sedentary person, consuming more than 40 grams of processed carbohydrates per meal can lead to reliance on insulin, which should be a failsafe, not the norm.
💪 Skeletal muscle, making up 40% of body weight, uses as little as 2 grams of glucose per hour at rest, indicating it is not a primary glucose user when sedentary.
⚖️ A foundational dietary approach suggests a 1:1 ratio of protein to starchy carbohydrates to improve glucose and insulin regulation, aiming to reduce the current 6:1 carb-to-protein ratio seen in American diets.
🌱 The minimum carbohydrate need is 80 grams, with the RDA being 130 grams (including a 50 g buffer). Carbohydrate tolerance should be determined by exercise levels; endurance athletes may need 400–500 g.
Protein Intake and Benefits
🥩 A good diet structure involves one-third of the plate from protein, one-third from fruits/vegetables, and one-third from starchy carbs (excluding fruits/vegetables from the starch count).
🌱 While plant protein can supply necessary amino acids, studies suggest that consuming less than 30% of protein from animal sources may lead to deficiencies in essential micronutrients like iron, zinc, and B12.
📈 Increasing protein intake (25–35% of calories) stimulates the release of hunger-regulating hormones like GLP-1 and CCK, improving satiety.
⏱️ Protein timing around exercise (anabolic window) is less critical than total daily intake and distribution; however, hitting 30–50 grams of protein in the first meal post-fast stimulates satiety hormones for 3–4 hours.
Mistakes for Individuals Over 40
🚫 Common mistakes include nighttime overeating (e.g., "I just deserve this" mentality) and prioritizing cardiovascular activity over resistance training (3–4 days a week) to maintain muscle mass.
🏃♂️ High-Intensity Interval Training (HIT) should be utilized by all populations (male/female) for its proven benefits on max, body composition, and cardiometabolic health, including improved insulin sensitivity in conditions like PCOS.
📅 A key failure point is not planning meals; utilize food prepping or a meal prep service to ensure consistency, recognizing that hunger is not an emergency.
Key Points & Insights
➡️ Prioritize protein intake to manage satiety, regulate blood sugar, and ensure micronutrient sufficiency, moving away from high-carb meals that spike insulin.
➡️ Determine carbohydrate tolerance through activity; sedentary individuals should limit starchy carbs, especially those exceeding 40 g per meal, unless coupled with significant physical activity.
➡️ Do not neglect resistance training; individuals over 40 must prioritize lifting to counteract age-related muscle mass decline, even when time is scarce.
➡️ Structure your plate around equal ratios of protein and starchy carbs (1:1), while focusing on foods with a favorable carb-to-fiber ratio (like broccoli, 1.7:1) over low-fiber options (like bananas).

Dr. Gabrielle Lyon reveals the biggest mistakes Americans make with their nutrition and body composition, especially after age 40. With 75% of Americans overweight or obese, the problem is clear: excess calories from cheap, processed carbohydrates.
Dr. Lyon dissects the metabolic science, explaining why skeletal muscle—the largest organ—is not designed to dispose of the massive carb loads found in the average American diet.
Nick Barringer is an expert on nutrition and performance for the tactical athlete. Nick Barringer currently serves as the Program Director for the Army-Baylor University Master’s Program in Nutrition.
