Prednisone curveball during Mounjaro maintenance: scale moved, appetite too

i've been in maintenance for about 14 months after losing on Mounjaro, and I keep a boring 5-pound window. Last month I had to take a short prednisone course for an asthma flare.

By day three my appetite was noticeably louder and the scale was up 4.6 pounds. My first instinct was panic — like the old food noise had moved back in for good.

But my energy was normal, my usual walks felt the same, and I was drinking more water than usual. I didn't start cutting calories or making panic tweaks; I kept my normal protein, movement, and sleep, and checked in with my doctor.

It settled back down over the next week or so. The medication was temporary. The maintenance habits are what stayed.

For anyone who's had a steroid burst while on a GLP-1, how do you tell a temporary medication bump from a real regain trend without spiraling?

I had a similar curveball with a steroid burst for a flare last fall. I kept logging but switched my focus to a 7-day median instead of daily numbers, plus morning waist and ring fit.

The scale jumped ~3 lb by day two, appetite was loud, then both settled about a week after the last dose. My 5-lb window survived. How many days out from the course are you? If you’re still in the first week post-steroid, I’d treat that 4.6 as noise and watch the trend, not the single weigh-in.

I’ve had two prednisone bursts for asthma too. The appetite roar hit me around day 2–3, but the scale jump was mostly fluid — my rings got tight and my face looked puffy.

I didn’t treat that week like a real gain: logged food as usual, kept my walks, focused on water/protein, and ignored the number until about 10 days after the last pill. My 7-day average settled right back near my window. Curious — did you notice any puffiness/swelling, or was it purely the food noise coming back?

I’m wired the same way — daily weights, 7-day median, waist tape. When I had a steroid burst for a flare, the scale jumped 3.9 lbs by day 4, but my waist was only +0.2 in and the 7-day median didn’t really budge until day 6.

The louder appetite was the real wild card; I logged hunger 1–5 and it peaked days 2–4, then faded. If you’re only watching the scale, that 4.6 is mostly noise.

Are you tracking waist or hunger scores alongside it? That’s the only thing that kept me from spiraling.

Tbh curious whether you looked at weekly averages vs the daily number. When I had a steroid burst for an asthma flare, I was up ~5 lb by day 4, but my waist tape barely moved.

Most of it whooshed off over the next 5–7 days; appetite lagged a bit longer, maybe 10 days. I kept logging normally, prioritized protein and walks, and didn’t change my maintenance range.

Did your 4.6 lb come off after the course ended, or is it still hanging around?

One thing that helped me separate steroid noise from real regain was tracking my “water tells” alongside the scale: rings, sock lines, and whether I woke up puffy. During my short burst, my appetite was loud but my actual portions barely budged—the number was mostly fluid for me.

I kept meals boring and anchored: same protein-heavy breakfast, big volume lunch, normal dinner, no “might as well” foods. The scale took about a week to start dropping in fits after the appetite calmed.

Did your hunger settle before the scale did? That lag messes with my head every time.
