First, define "not working"
Is the scale stuck? Has appetite returned? Are you losing inches but not pounds? Each of these points to a different cause and a different fix.
Common reasons tirzepatide stalls
Dose too low for too long, missed weekly doses, under-eating protein, dropped strength training, poor sleep, and high stress all blunt results. Sometimes it's one. Often it's three.
The food side of the equation
Tirzepatide reduces appetite, which often means people eat too little — and the body adapts by slowing metabolism. Protein and meal timing matter more on a GLP-1, not less.
The dose conversation
Most people need to climb to a therapeutic dose to see steady results. We review dose, timing, and tolerance with each patient and adjust when the data calls for it.
What we do when results stall
We pull recent labs, body composition, and food logs. We look at sleep and stress. We rule out under-eating before we adjust dose. The fix is almost always in the protocol around the medication.
If you've been on tirzepatide for months and feel stuck, a fresh set of eyes on the plan usually unlocks the next phase.
