How to Lose Fat & Gain Muscle With Nutrition | Alan Aragon

What It Covers

Alan Aragon clarifies evidence-based nutrition and training protocols for fat loss and muscle gain, debunking myths about protein timing, fasted training, seed oils, and meal frequency while providing specific macronutrient targets and flexible dietary approaches.

Key Questions Answered

• •Protein Per Meal: Muscle protein synthesis maximizes at 0.4-0.6 grams per kilogram body weight per meal (roughly 0.2-0.25 grams per pound). Recent studies show 40-100 grams post-workout can be beneficial with higher training volumes, contradicting the old 30-gram ceiling myth that dominated research until 2016.
• •Total Daily Protein Priority: Total daily protein intake matters far more than timing around workouts. Consuming 1.6 grams per kilogram body weight (0.7 grams per pound) daily produces equivalent muscle gains regardless of meal timing, as the anabolic window extends 24-72 hours post-training, not just hours.
• •Fasted Training Reality: Training fasted burns more body fat during the workout, but total daily fat oxidation remains identical when total calories and macros match fed training conditions. Choose based on personal preference and performance, not fat loss optimization, as the metabolic advantage disappears over 24 hours.
• •Body Recomposition Protocol: Simultaneous muscle gain and fat loss occurs reliably at 10% caloric surplus with protein intake between 1.0-1.5 grams per pound body weight. Studies show adding 80-100 grams protein daily above habitual intake promotes fat loss without conscious calorie restriction through increased satiety and thermogenesis.
• •Seed Oil Evidence: Canola and soybean oils show better health outcomes in controlled trials compared to animal fats like butter and lard. The vilification lacks scientific support, with most concerns about processing methods not translating to measurable adverse health effects in human intervention studies at typical consumption levels.
