That approach works from a pure energy balance and weight loss perspective but often collapses during body recomposition when you're trying to lose fat and build muscle.Discover why the traditional nutrition hierarchy is backward and the 5 specific mistakes that prevent successful body recomp. Learn the bottom-up framework that makes simultaneous fat loss and muscle gain actually work.You'll understand why micronutrients drive metabolism and energy production, how flexible dieting fails without nutrient anchors, the fiber sweet spot for body recomp, why perfect macros can't overcome poor training performance, and how to use biofeedback instead of just tracking calories.This episode gives you a practical system to optimize nutrition for strength training, muscle building, and sustainable fat loss without feeling hungry, weak, or stuck on a plateau.Timestamps:0:00 - Flipping the nutrition pyramid for body recomposition 2:52 - Micronutrients and body recomp 7:12 - Constraint theory and metabolic bottlenecks 12:16 - Carbs, fat burning, and ATP 17:11 - Building nutrient-dense meal patterns for muscle gain 20:36 - Flexible dieting with nutrient anchors (not just IIFYM) 25:56 - The fiber "sweet spot" for digestion and metabolism 31:20 - Macro targets that support strength training performance 36:12 - Meal timing and tracking gym performance 40:10 - Using biofeedback over blind calorie trackingSupport the show Get Fitness Lab - Philip’s science-based AI app for fat loss, muscle building, and strength training for people over 40.
