Week 52 on tirzepatide, scale flat but labs shifting

Week 52 of tracking: scale flat for 9 weeks, labs still shifting. SW 241, CW 178. The scale hasn't moved since week 43, but hs-CRP dropped from 6.8 to 2.1 and ALT from 41 to 24. Waist down 1.5 inches. Fasting glucose steady around 92.

Keep thinking about that 72-week trial with 2539 people and the 5/10/15 mg groups—did anyone else see a long plateau while inflammation markers kept improving? Trying to figure out whether to care more about the scale or the labs.

Curious what tracked for everyone else—weight, waist, bloodwork, sleep, whatever.

The scale plateau with shrinking waist happened to me too. Mine lasted about 11 weeks. I cared way too much about the number.

hs-CRP from 6.8 to 2.1 is a big move. Did you have any infection or flare around the first draw? That can muddy things.

I track fasting glucose. Mine bounced around 90 while weight was flat, then settled. Not medical advice, just what I logged.

That 72-week trial is the one worth bookmarking. 2539 people, 5, 10, and 15 mg arms, primary period running all the way out to week 72.

Which is a big part of why a 9-week flat stretch reads as common enough that calling it a true stall is probably premature. That said, waist and hs-CRP moving at the same time is genuinely interesting.

Common surprise: lab logistics can produce that pattern on their own. Were both draws at the same lab, same time of day?

ALT especially bounces around until fasting morning draws get standardized and hard workouts are skipped the day before. And worth knowing before comparing anything: did fasting glucose sit around 92 for the whole plateau, or just on draw days?

I started doing fasting morning draws too. My ALT finally stopped looking random.

My scale stalled weeks 30-42 but my rings got loose. I wish I’d taken more waist measurements earlier.

I don’t fully buy that a 9-week flat stretch is just normal. If intake and steps are unchanged, my first suspects are sleep and stress, not the drug.

Sleep is my big variable. Bad week of night shifts and my fasting glucose jumps 8-10 points.

The trial comparison is useful, but real life isn’t a controlled 72-week protocol. I’ve been logging weekly since week 1 and my weight trend flattened twice while my waist kept dropping.

What helped me was zooming out to a 4-week average instead of reacting to every weekly weigh-in. Your hs-CRP drop from 6.8 to 2.1 would keep me motivated even if the scale didn’t move. Have you checked hydration or sodium around weigh-ins?

I know for me a high-sodium weekend can hide 2-3 lbs of water for days. Also, are you measuring waist at the same spot first thing in the morning? That changed my numbers a lot.

The 4-week vaerage thing saved my sanity. Weekly numbers are noise unless I’m constipated, honestly.

Week 47 for me and my scale sat at 174 for 11 straight weeks, but my closet was the honest one. I finally pulled the jeans I'd kept in a bin since 2019 and they zipped without the lying-down trick, and I went from a 38 waist to a 33. If your waist dropped 1.5 inches, the scale is just lying by omission.

My flat stretch ran 12 weeks and I traced a lot of it to weekends, not the meds. Friday takeout plus two restaurant meals would put me up 3-4 lbs by Monday, then it would whoosh off by Thursday, so every Monday I thought I'd stalled and every Thursday I thought I was a genius.

I started logging sodium for two weeks and it was ugly, like 4,000 mg on Saturdays. Bumped my sleep from 5.5 to 8 hours around week 46 too, and the Thursday whoosh got way more consistent.

Not saying that's your thing, but worth checking what your Monday and Friday mornings look like before you blame week 52.

Honestly the tape measure has been way more honest than my scale for like six months.

I'd gently push back on just waiting for the scale to catch up.

At week 40 I added two lifting sessions a week and the scale sat at 182 for ten weeks, but my grip and my stairs got noticeably easier and my resting heart rate went from 69 to 62. Weight is the noisiest number I track. Are you doing any resistance work, or mostly walking?

Week 38 here. My 11-week flat lined up almost perfectly with a stretch of 5-to-6 hour nights during a work crunch, and my resting heart rate crept up around the same time.

Sleep got back to 7.5 and change, and 4 lbs came off over about three weeks with literally nothing else changed. Not saying that's your deal, but the nights are worth a look.

Went 12 weeks flat and finally caught myself: I'd drifted into grazing from 4 to 9pm without logging a bite of it. Once I added a real 40g protein lunch and stopped the kitchen wandering, the scale moved 3 lbs in five weeks. Slightly humbling that I'd spent weeks blaming my metabolism instead of my evenings.

Your CRP and ALT moving like that while the scale naps is honestly the better headline here.

Comparing week 52 to that trial might be the wrong yardstick, since they were measuring weight endpoints and yours are measuring stuff the trial never tracked. What are your lifts doing?

I started strength work around week 40, scale sat frozen two months, but my deadlift went from 95 to 155 and stairs stopped being a negotiation.

At week 46 I ditched the daily scale and used a pair of 33-inch jeans as the referee. Weight sat at 181 for seven weeks, but I went from not buttoning them to needing a belt, and my gym shorts started falling down on the treadmill.

Weirdly, the scale finally dropped 2 lbs the week I stopped weighing daily. Bodies are obnoxious.
