How Much Protein Do You Really Need for Longevity? | Evidence-Based Guide with Dr. Rupy Aujla

How Much Protein Do You Really Need for Longevity? | Evidence-Based Guide with Dr. Rupy Aujla

Author: Sarah Ann Macklin September 17, 2025 Duration: 1:24:02

Protein is at the forefront of health and longevity research. But how much do you really need? And is it just about muscles, or does protein hold the key to aging well, preventing frailty, and protecting long-term health?


This week’s guest, Dr. Rupy Aujla, NHS GP, nutritional medicine expert, and founder of Doctor’s Kitchen, takes us inside the science of protein, inflammation, and longevity. From his own story of reversing atrial fibrillation through lifestyle change, to the cutting-edge research that’s shifting how we think about diet and healthspan, Rupy brings both expertise and lived experience.


Together we explore:

– How much protein you really need: why the old 0.8 g/kg guideline is outdated and what to aim for now

– Protein timing: how protein distribution impacts muscle, bone, and immune health

– Women, fertility & menopause: how aging changes protein needs and why women may benefit from more

– Beans, lentils, and plants: why plant proteins are powerful but not always enough

– Anti-inflammatory eating: what the Dietary Inflammatory Index reveals

– Silent killers of aging: how falls and frailty shorten lifespan even more than many chronic diseases

– Longevity fads vs facts: NAD drips, supplements, and what really works

– Practical eating: a simple framework to build plates high in protein and flavor


Love,

Sarah Ann 💛
