Alan Aragon, evidence-based nutrition researcher who simplifies protein and diet for trainees. Dr Brad Schoenfeld, hypertrophy scientist and former bodybuilder studying muscle and training. They discuss protein targets, recomposition versus surplus, effort and failure in training, recovery strategies, cardio-resistance balance, and practical training frequency to preserve muscle with age.

Episode notes
INSIGHT

Aging Blunts The Anabolic Response

  • Older muscle shows a blunted anabolic response, needing larger protein doses to stimulate muscle protein synthesis than younger muscle.
  • Alan explains older adults may require roughly double the per-meal protein (and more leucine) to reach the same MPS response seen in youth.
ADVICE

Begin Resistance Training Now To Reverse Losses

  • Start resistance training at any age — older adults can gain substantial strength and meaningful hypertrophy in weeks to months.
  • Brad cites studies showing 75+ year olds and even nonagenarians gained large strength and functional improvements with simple programs.
INSIGHT

Plant Protein Differences Grow With Age

  • Plant versus animal protein differences matter more in older adults due to leucine threshold and satiety issues.
  • Brad notes younger people show little difference, but older adults may need leucine‑fortified or higher total plant protein doses.
