Week 52 on tirzepatide: scale flat, labs still shifting

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.

My 11-week plateau had less to do with food and more to do with a brutal work stretch: bed at 1 a.m., 5.5 hours sleep, two coffees by 10. I took a long weekend with no alarm, slept 8 hours, and dropped 3 lbs of what I can only assume was stress puff. Since then I guard my 10:30 lights-out like it’s a meeting.

I added two 30-minute walks after dinner and one basic lift day, and the scale ignored me for eight weeks. Annoying. But my resting heart rate went from 68 to 62, I can do 10 real pushups now, and my usual 3-mile loop feels flat instead of hilly. That’s the stuff that keeps me from chucking the whole routine.

Week 52 and still shifting underneath is honestly the most encouraging flat scale story I’ve read.

Have you tried measuring the same spot at the same time of day? My morning waist and my 8pm waist are basically different people.

Six months in I started logging sleep right next to my weight and it got gross how obvious it was: under 6 hours and I hold 2-3 lbs of water for days, no matter what I eat. A stressful stretch at work did the same thing. Neither one moved my waist an inch, which is the part I keep coming back to.

I’d argue after week 40 the scale is the least interesting column. I track waist-to-height ratio (WHtR) because height doesn’t fluctuate; during my own 10-week flat stretch weight stayed inside a 1.8-lb band but WHtR went 0.57 → 0.53. That trendline was almost perfectly linear. Did you calculate yours yet? Also, is your fasting glucose 92 a single draw or a monthly median? Mine swings 88–97 based on dinner timing, so I only compare monthly medians—otherwise I’d drive myself nuts.

Fellow dorm-dweller here. My 11-week flat coincided with my body apparently deciding to renovate instead of move out—same scale, but I could suddenly do the stair climb to my 4th-floor class without sounding like a dying accordion. I started a dumb phone note: “flights before winded,” “pushups before bed,” “jeans button at 6pm” (the real bloating test). Cheap protein rotation: tuna packets, cottage cheese, lentils, eggs. Not glamorous, but it kept me from rage-quitting the scale. Did your energy or appetite noise change during the flat stretch, or mostly just labs/waist?

The plateau itch is real. I do the cooking at an assisted living place, and what showed me progress off the scale was just counting the spoon tastes I take while prepping trays. Switched to a little custard cup for QC and keep seltzer on the counter so I stop grazing out of habit. Weight didn't budge for eight weeks, but the apron strings kept moving. Anybody else notice the energy on a long shift, or your rings fitting differently alongside those labs?

Honestly, flat scale + CRP/ALT dropping + waist down screams recomp to me. The thing I’d be watching is your lifting log: are your top sets still adding reps or load? When I stalled for ~10 weeks, my weight didn’t budge but my squat and RDL numbers crept up and my arms finally started looking different in progress pics. If training is progressing and protein is consistent, the scale is just the least useful metric in that window. What are your main lifts doing right now—holding, or still moving?

late-night gamer here too. my scale went flat around month 10, but my watch showed resting HR creeping up while the scale sat still. Hydration and rough sleep show up there first for me.

Been around since the old plateau threads, and the ratio stuff kept me sane. I had an 11-week flat around month 10; scale didn’t budge, but waist-to-height went 0.54 to 0.49, resting HR dropped ~4 bpm, and my monthly same-jeans photo finally showed it. Weekly averages were flat too. Curious whether you track waist-to-height rather than just inches? Crossing under 0.5 meant more to me than the scale. Also, did sleep or step count change during those 9 weeks? That was my hidden variable.

Did your steps or sleep shift around week 43? My 11-week flat started after a work crunch cut steps from ~9k to ~5k and sleep from 7.5 to 6. I didn't change anything med-wise; just reinstated 30-min post-dinner walks and 2x/week full-body lifts. Scale stayed flat another month, but resting HR fell 6 bpm and my lifting log kept climbing. If you have HRV or sleep data, that's the first place I'd look before calling it a true stall. Sometimes the scale is just the last variable to move.

I do load-ins for touring shows, so sleep comes in weird blocks, and my waist tracks those blocks more than it tracks what I eat. Weeks with two full 8-hour sleeps in a row, the waist shrinks even when the scale won't budge. I measure same spot, plus how my tool belt sits at hour 8. Do you weigh after sleeping or after a work day? I used to weigh at the end of a call — useless. Now it's right after I wake, fasted, and the trend reads like a trend again. Weigh timing can fake a plateau.

I had a 13-week flat around months 9–12. DEXA showed fat mass down 5.4 lb, lean up 2.9, and total water up ~1.5 L, so the scale was masking it. BIA was too noisy to trust day to day. If you haven’t, a repeat DEXA (or tape + same-lighting pics) might separate fat loss from water/lean shifts. Sharp question: did your 1.5 inches come off gradually, or in a whoosh after a higher-carb/deload week? Mine finally moved after a vacation with more carbs and sleep, which made me wonder how much was glycogen/water. Also curious whether your fasting glucose steady at 92 feels different from earlier in the year.

At week 52 I’d track non-scale metrics that actually move: neck/thigh circumference, grip strength, resting HR, and weekly step average. My own 11-week flat lined up with a step drop (8k→5k) and zero lifting; restoring both got the scale creeping again. Not causal, just n=1. What’s your current resistance-training frequency and step count versus week 43? That’s often where the plateau answer hides.

Road warrior here—airport scales, hotel mirrors, restaurant sodium, the whole circus. What finally helped my flat-scale brain was tracking non-scale stuff that travel can’t fake: same belt notch, same pair of jeans after a flight, resting HR from my watch, and a monthly photo in the same hotel gym mirror. My resting HR kept easing down while the scale sulked for weeks, which matched the tape moving in little stair-steps rather than weekly. Curious: has your waist change been steady or did it come in bursts? I’m wondering if 9 flat weeks is just your body doing behind-the-scenes remodeling before the next whoosh.

Flight attendant, three time zones in a week. Weighing in after a redeye versus after an actual night's sleep moves me 3–4 lbs, and airport food does the same thing. So daily weigh-ins are gone. I do one a week — same day, after sleep, before coffee. Waist-to-height is my other check; at 5'9" I watch for anything past 0.5. You're probably right around there too. But I'm actually asking: does every weigh-in land at the same point in your sleep cycle? If not, that flat scale could be timing, not a real stall.

Fellow broke dorm dweller here. My scale’s been flat ~8 weeks too, so I started a dumb little spreadsheet: protein per dollar (cottage cheese, canned chicken, lentils, eggs) and how many meals I actually chew vs drink. Scale sulks, but budget and energy are up. Weirdly helpful. Sharp Q: did your hs-CRP/ALT shifts line up more with sleep/stress changes or with the waist loss? Trying to decide what to track when the scale plays dead.

yo week 52 is wild. one thing that helped me: i switched from daily weigh-ins to a 10-day rolling median, and my "flat" stretch was actually a slow 0.3 lb/week downtrend hidden by water swings. also started logging resting heart rate and sleep—both improved while scale sat still. did your clinic run a body comp or just scale/labs? curious if lean mass is holding while fat mass keeps dropping. your crp/alt shift feels like the real story, not the scale.

Your hs-CRP/ALT drop plus waist loss sounds like real recomposition, not a stall. I had a similar 12-week flat scale stretch; what finally gave me useful data was a DEXA scan, not the scale—fat mass down 6 lb, lean mass basically unchanged. I also tracked neck and hip, not just waist. Did you get any body-comp scan, or just labs and tape? Curious whether fasting insulin or A1c moved too, since glucose can look steady while other markers shift.

At wk 52 too. Scale flat since wk 44, but DEXA last month: -3.8 lb fat, +1.2 lb lean, waist -1.5". RHR down 5. That's the data I care about. If you don't have DEXA, tape + photos + strength metrics are cheaper. The 72-wk trial's weight curves flatten while A1c/CRP keep improving, so flat scale isn't necessarily stalled biology. Curious: how's your protein and resistance training volume? That's where I'd eyeball first.
