I started liraglutide 3.0 mg six weeks ago. Scale is down 4.8 lb from baseline, but the trend stalled this week.
Appetite changed around week 3 and I'm eating smaller portions without really trying. Fasting glucose went 92 to 89.
Resting HR went 62 to 69, which I did not expect. I wear a chest strap and measure before coffee.
Anyone else tracking resting HR or labs? Did yours settle after week 8, or keep drifting?
I'm trying to figure out if this is just me.
Resting HR 62 to 69 is a big jump for six weeks. Mine went 58 to 63 by week 5, then eased to 61 by week 10.
My fasting glucose barel ymoved, 95 to 93. The HR thing was more obvious. I stopped caffeine for a week and it dropped maybe 2 bpm.
Honestly, I dug into NCT03560336 because I wanted numbers beyond forum anecdotes. It was a completed rPMS study with 758 enrolled. The RAW data I found didn't include numerical efficacy or safety results, so it didn't answer my resting HR question.
That said, your chest strap data is probably more useful for your own trend than any single trial. Are you logging sleep and alcohol? Those moved my morning HR more than anything else, and the week I had two drinks my HR was up 4 bpm for three straight days.
The pattern seems to be it settles around week 9. The first six weeks are noisy.
I wouldn't read too much into a 3-point glucose shift. Meter variance alone can do that. The HR trend is the interesting one.
Sleep is the missing variable for me. Bad sleep nights add 5 bpm. Good sleep and I'm back to baseline.
Caffeine is a bigger lever for me than I thought. Cutting my second cup took 3 bpm off in a week. Did you taper or go cold turkey?
Week 7 here and my RHR did a similar weird hop: 57 to 65 around weeks 4-6, then it eased back to 60 by week 10. The thing that actually explained it for me wasn’t just the med—it was sleep debt plus lae salty dinners; on nights I slept under 6 hours my chest strap showed +6-8 bpm the next morning, and on normal nights it was +2.
The surprise was that my scale stalled for 11 days in week 6 while my waist at the navel went down 1.25 inches, so I stopped treating daily weight as the only signal and switched to Sunday morning waist + weight. Fasting glucose for me barely budged until I cut the after-dinner snacking, then it dropped maybe 4 points, but that’s just my n=1.
I logged the HR bump and mentioned it at my next appointment; mine settled after week 8.
Week 5 here, and my scale flatlined for 11 days after a 4.2 lb drop, then dropped 2.3 lb overnight after a salty pizza Friday. The surprising part was my waist tape moved first—down 1.1 inches at the navel while the scale sat still—so I switched to a Sunday waist check plus a 7-day weight average, and the stall felt way less demoralizing.
I also caught myself undoing smaller dinner portions with standing-at-the-counter snacking after 8 p.m., so I started pre-portioning a bowl and actually sitting down, and the trend line resumed. Are you measuring waist or just scale?
If your portions are naturally smaller, I’d bet a 7-day average shows progress before the scale does.
late night gamer here. the thing that moved my rhr more than the scale was sleep timing + late sodium.
if i play till 2am and eat a salty snack, my morning strap reading is +5-8 even when i get 7h. i started logging bedtime and last food/drink time beside the rhr and it was mostly the 1am carb/salt bomb and broken sleep, not some mystery.
soda-swap wise, going to zero after 8pm seemed to help after a couple weeks, but regular soda late was brutal. are you tracking sleep/meal timing with the rhr, or just the number?
My RHR tracks training load more than anything else. Adding a fourth lifting day and heavy squat volume pushed it up 5-6 bpm for about 10 days; a deload brought it back. Sleep stayed solid, HRV just looked flat. Are you logging session RPE/volume?
During flat scale weeks I lean on waist tape, progress photos, and top-set strength—my weight stalled for two weeks while my bench and rows moved. That’s usually recomp noise for me, not a true plateau.
Nice data collection. One thing I track with RHR: temperature/humidity and hydration. My RHR jumped 6–8 bpm for a week during a hot spell when I was under-drinking; scale also stalled, then both eased. Fasting glucose 92→89 is a win, though. Are you logging sodium/potassium or evening carbs?
If portions shrank fast, that can shift fluid balance and tick RHR up without meaning much. I’d stay zoomed out and compare your 7-day average to the prior 7-day. Has your HRV or respiratory rate moved too?
I track RHR with a chest strap too. My +6 bpm early on correlated with lower HRV and sodium/fluid intake, not training load.
Adding electrolytes and a small carb+protein snack before noon settled it back within 3–4 bpm over ~10 days, while fasting glucose stayed down. Worth adding HRV and orthostatic HR to your morning set—if the RHR bump is autonomic, HRV usually moves opposite. What’s your HRV trend?
That’ll separate recovery strain from lower glycogen/calorie flux.
