I started this the week my doctor and I first talked about coming off. For once, the day I stop didn’t feel like a cliff. I knew what each week would look like, what to expect, and what to do when the hunger showed up. Calm instead of dread. That alone was worth it.

Real members on what Stay This Size did for them
Hear it in their own words — how Stay This Size helped them hold onto their progress and finally feel in control of it.
On a GLP-1, losing the weight isn’t the hard part. Keeping it is.
Most plans are built for willpower: eat less, try harder. On a GLP-1 that’s the wrong problem. The shot makes losing easy. The real work is what your body does while you’re on it, and what happens the day you stop.
- The fear of regain shows up from your very first shot, not just at the end.
- The early weeks are when many people quit, often before the medication even works fully.
- Some of what you lose is muscle, the engine that quietly keeps weight off.
- When you stop, your hunger comes back. That’s biology, not willpower.
- Do nothing to prepare for it, and the weight can return faster than it came off.
- And almost no one gives you a plan for the whole thing, from day one to life after.
So this isn’t another diet. It’s one ordered plan built around the whole journey, the first weeks, the months on the shot, the taper, and life after, designed for the way your body actually changes on a GLP-1, so the weight you lose becomes the weight you keep.
Every worry below comes straight from people on this journey. Here’s the part of the plan built for each one.
The first weeks were rough. I had no idea what I could actually eat.
I just started, and I’m already dreading the day I come off.
I’m losing the weight, but I’m scared I’m losing muscle with it.
Honestly, my biggest fear is being off of it.
When the food noise comes roaring back, I cave at night.
I just want someone to tell me what to eat.
People act like it doesn’t count because it was the medication.
I can’t stay on this forever, and I don’t want to.
A GLP-1 quiets your appetite for a while. That quiet is a window, a rare chance to build the few things that make weight stay. Most people let it close unused. Stay This Size walks you through it in order, from your first injection to long after your last, working with your body instead of forcing it.
Get through the start without quitting
The early days are when most people struggle, and when many give up before the medication even does its job. Week by week you settle in: the gentle foods that go down easy, a simple water habit, a short daily walk, and protein-first at one meal. By the fourth week those few anchors run on their own, and the hardest stretch is behind you.
Build while it’s easy
This is the heart of the window. With hunger quiet, you begin two short at-home strength sessions a week and make protein-forward eating your easy default. You also learn the why: muscle does the quiet work of holding your weight, so protecting it now is what makes the results last.
Come off without the fear
Stopping becomes a planned step-down. First you pre-load your routine so it can catch you, then you walk the weeks off one at a time: expect the hunger and meet it, hold your strength and protein steady through the stretch most people regain in, and let your appetite settle into a new normal, proof it’s your routine holding the line, not the drug.
Stay this size for good
A light, repeatable weekly routine holds what you built, and a simple, pre-planned reset handles the normal wobbles so one slip never turns into starting over. From here it isn’t a diet or a phase, it’s just how you live. This is the part that makes it the last time.
Everything you need, for the whole journey.

What members say


The early weeks nearly made me quit. Nothing sounded good and I had no idea what to eat. Having a gentle, week-by-week plan and meals that actually went down easy is the reason I didn’t give up. I felt looked after, not lectured.

When people would say “wasn’t that just the medication?”, I never had an answer. Now I do. The routine I built is what’s holding this, and I know it. I stopped feeling like I had to apologize for how I got here.

The quiet in my head around food was the thing I was most scared to lose. Sticking with the eating rhythm kept it steady even after I came off. Still a work in progress some days, but I don’t feel like I’m white-knuckling it anymore.

The cravings always hit hardest at night. Having a calm voice to put on, instead of standing at the fridge feeling alone, changed everything for me. It’s the part I didn’t know I needed.
