Over 70? THIS $1 Food Builds Muscle FASTER Than Protein Powders | Dr. William Li

After seventy, many believe muscle loss is inevitable — but new research reveals a very different story. In this video, Dr. William Li uncovers how two of the simplest, most affordable foods — the humble egg and lentil — can reignite your body’s ability to build muscle naturally, even when protein powders fail.

You will discover how these foods work deep inside your biology, reawakening dormant pathways that control muscle synthesis, mitochondrial energy, and hormonal balance. Dr. Li breaks down the cutting-edge science behind anabolic resistance, insulin sensitivity, and the muscle-brain connection — showing how aging muscle can regenerate when given the right signals.

This is not about quick fixes or supplements. It is about understanding how your body’s intelligence uses real food to restore strength, energy, and longevity — from the inside out.
