What the research suggests and what it does not

Research on GLP-1 treatment does not give a simple promise about what happens after stopping. In the SURMOUNT-4 trial, adults who completed 36 weeks of tirzepatide and were then switched to placebo gained 14.0% of body weight from week 36 to week 88, while those who continued tirzepatide lost a further 5.5%.

That finding suggests weight regain can happen after treatment changes for some people. It does not tell any one person what will happen, and it does not show that any single habit can prevent weight regain after GLP-1 on its own.

For that reason, many people focus on tracking rather than guessing. The app is planned to help you record a weekly weight trend, a protein target from body weight, a fiber target from body weight, and strength sessions in one place. It also plans a taper timeline that only records the dose steps you type in, without suggesting or calculating doses.

If you want more context on muscle and strength during this time, see muscle loss on GLP-1.

Habits people track: weight trend, protein, fiber, strength

People who want to prevent weight regain after GLP-1 often track a few basic inputs because they are easy to review over time. The app is planned to keep this simple and private on the device, with no account, export and delete everything, and a free tier plus an optional Pro subscription.

Weight trend: not just one weigh-in, but the direction over time.
Protein: the joint advisory from ACLM, ASN, OMA and TOS notes the adult RDA is 0.8 g of protein per kg of body weight per day and says higher suggested targets of 1.2 to 1.6 g/kg per day have been suggested during active weight loss.
Fiber: adults are encouraged to eat more fiber-rich foods such as vegetables, beans, fruit and whole grains, and to increase fiber slowly and drink water.
Strength: the app is planned to include a strength log that aims for 2 to 3 sessions a week, which may help you see whether strength work is happening consistently.

The protein advisory also notes that it is unclear whether to calculate protein from actual, adjusted, or fat-free mass, and that protein alone is not enough without strength training. People with kidney disease or a clinician-set limit should follow their clinician.

None of these tracking items is a rule. They are simply ways some people stay oriented while they talk with their care team about what fits their situation.

Why a weekly trend helps

A single day can be noisy. A weekly trend can make it easier to notice whether weight is drifting, holding steady, or changing in a way that deserves a conversation. That is why the app is planned to show a weekly weight trend and let you set an adjustable regain band.

An adjustable regain band may help you see when a change is outside your usual range, without turning every small fluctuation into a problem. It is not a forecast and it is not a goal. It is just a visual reference.

Weekly review can also make the other pieces easier to use. If protein, fiber, or strength tracking is hard to remember day to day, looking back once a week may help you notice patterns. For readers who want a closer look at the feature itself, see weight trend and regain band.

Because the app stores data on the device, this review is meant to stay private and simple. The goal is not to judge your habits. It is to make tracking easier if you want a record to bring to your next visit.

What no app can promise

No app can promise to prevent weight regain after GLP-1, protect muscle, or tell you the right way to manage a medication. Those decisions belong to your prescriber or care team.

No tracker can diagnose why weight changes, predict what will happen next, or replace medical care. Even with careful logging, weight can change for many reasons, and not all of them are visible in an app.

The planned app can help you record what you choose to track, but it will not calculate, validate, or suggest doses. It will not give medical advice, and it will include a medical disclaimer so the limits are clear.

If eating feels hard, or if tracking food feels stressful, talk to a clinician. A calm plan is usually better than trying to do everything at once.

Talk to your care team

If you are tapering, have stopped, or are maintaining after a GLP-1 medication, your care team can help you decide what matters most for your situation. That may include how often to check weight, whether protein or fiber need attention, and whether strength training is appropriate for you.

You can also bring a few simple notes to the visit: your weekly trend, any regain band changes, your strength log, and any questions about appetite, energy, or eating. Those notes may make the conversation more specific.

Adults with kidney disease or a clinician-set protein limit should follow their clinician. And if eating feels hard, please bring that up directly so you can get support that fits your needs.

The app is planned as a free reference plus calculators for adults 18+ who want a private way to track these basics after GLP-1 treatment.
