In this episode of Anabolic Analysis, I sit down with author of the ISSN position stand on dieting, and pioneer of the evidence-based fitness movement, Alan Aragon to break down some of the biggest debates in training and sports nutrition.

We discuss Alan's current training, training to failure versus leaving reps in reserve, how many carbs and fats you need for hypertrophy, and why the commonly cited 1.6 g/kg protein target probably is not the ceiling for maximizing muscle growth.

We also dive deep into the calorie surplus debate. Do you actually need to bulk to maximize muscle growth? If so, how large should the surplus be, and can you minimize fat gain while still maximizing progress?

Finally, Alan shares several things he has changed his mind about, his best advice for building your physique over the next five years, and what he is currently experimenting with in his own training.

• Training to failure vs. reps in reserve
• How many carbs you need for hypertrophy
• Minimum dietary fat intake
• Why 1.6 g/kg of protein may not maximize gains
• Protein vs. carbs for additional calories
• Limitations of hypertrophy research
• Whether you need a calorie surplus to maximize muscle growth
• How large a muscle-building surplus should be
• Realistic rates of natural muscle growth
• Alan's thoughts on rep ranges, drop sets, and cluster sets

In this episode, Kolt speaks with King Deltoids, aka Braden, an exercise science student and bodybuilding content creator, about what actually matters in contest prep, muscle gain, and physique development. They cover high protein dieting in a steep deficit, whether you can build muscle while cutting, and the long running debate over needing a surplus to maximize hypertrophy. Along the way, they also dig into fatigue, failure, body fat levels, and why so much fitness advice breaks down once people try to apply it outside the lab.

Key topics

• Braden’s current prep setup
• How he structures full body training
• Protein intake during a deficit
• Fat intake stays at a minimum
• Why higher protein may matter more in harder deficits
• Protein is harder to store as fat
• Can you maximize hypertrophy in a deficit?
• The surplus debate
• How body fat level changes the recommendation
• Why a huge bulk is usually unnecessary
• Why body composition claims often get exaggerated
• Training failure, fatigue, and the brain
• Best advice for physique progress
