What usually goes wrong on GLP-1s

  • Appetite drops, protein falls, training intensity slips, and lean mass erodes along with fat mass.
  • People rely on the medication to do all the work and stop treating training as the protection strategy.
  • Scale loss is mistaken for a good outcome even when strength, energy, and tissue quality move in the wrong direction.

What the plan needs to do

  • Progressive strength work that is heavy enough to preserve output and signal the body to keep muscle.
  • Protein targets and simple meal structure that still work when appetite is low.
  • Simple weekly activity goals so strength training becomes a real habit instead of a good intention.

How to review the phase

  • Track bodyweight trend, strength performance, adherence, and recovery every week.
  • Use body composition or bloodwork data when it adds context rather than noise.
  • Keep the plan sustainable as dosage, digestion, appetite, and schedule shift over time.
