Fuel Tracking 101: Know What You Put In Your Body

The Nutrition-Calorie-Volume (NCV) framework simplifies meal tracking into three categories: Green (nutrient-dense, go-to meals), Yellow (moderate — fine in rotation), and Red (occasional treats). Instead of counting every calorie, you rate each meal and watch the ratio shift over time. Combined with health metrics like resting heart rate and recovery scores, you can actually see how your food choices affect your body within days, not months.
