Getting off sema — rebound weight experiences, how bad is it really

I'm approaching goal weight (down 54lb) and the fear of rebound is making me anxious about stopping. The STEP-4 trial data is discouraging — people regained ~2/3 of lost weight within a year of stopping.

But the trial stopped sema cold turkey in people who weren't necessarily doing anything else lifestyle-wise. I want to hear from people who tapered deliberately, kept lifting, tracked food. Is rebound inevitable or is it avoidable with a plan?

Currently on 1.7mg. Plan to step down to 1.0, then 0.5, then 0.25, then off, over ~16 weeks. Keeping strength training 3x/wk and ~180g protein. What am I missing?

Consider not going to zero. Staying at 0.1-0.25mg indefinitely is what a lot of veterans do. The metabolic benefit at microdose is real and the side effects are negligible. There's no trophy for quitting entirely.

Tapered over 20 weeks, kept training, stayed within 3lb of my stop-weight for 14 months and counting. The STEP-4 rebound cohort included zero behavioral intervention. If you're here and actively managing, your curve does not look like the average STEP-4 curve.

I came off fully and kept weight. Took 6 weeks for appetite to fully return post-last-dose, which was the danger window. That's when I doubled down on tracking and meal structure. Once I got past that I was fine on behavioral control alone.

Key variable: do you know why you gained the weight originally? If it was life-stage (post-partum, medication, injury), the driver may be gone. If it was chronic behavioral, the behavior needs a full replacement or you'll drift back. The drug didn't fix the original cause, it masked it.

@plateau_breaker this is the actual question. 'Will I rebound?' rephrased is 'has the original driver of my weight gain been resolved or just suppressed?' If suppressed, you will rebound. If resolved, you won't. The drug is orthogonal to that.

@plateau_breaker @dr_doubt this is the most useful framing I've gotten. My driver was honestly stress eating through a terrible job. Job is now gone. But the habit pattern isn't. I think I need to treat the post-sema period as 'behavioral work' not 'drug taper.'

Tapering sema over 16 weeks is not actually meaningfully different pharmacokinetically from stopping cold — half life is ~7 days, drug is mostly gone after 5-6 weeks regardless. The taper is a behavioral transition tool, not a pharmacologic one. Use the taper weeks to rebuild habits, not to ease off the drug.
