In trials, most of the weight came back within a year of stopping the shot.Make sure yours stays off.

Leanos is an AI coach for keeping the weight off after a GLP-1. Track calories, protein, steps, lifts and weight in one iPhone app and know where you stand. The Progress screen sets this week's average weight against last week's, so you see the trend under the daily swings.

Yes. It works whether you're planning to stop, stepping down, or already off, and for anyone holding or losing weight. Some people who held their weight after stopping say they built their habits while the food noise was still quiet, so the months before your last dose are a good time to start.

On average, most of it comes back. In the STEP 1 trial, people regained about two thirds of the weight they'd lost within a year of stopping semaglutide. In SURMOUNT-4, people switched from tirzepatide to a placebo regained 14% of their body weight over the next year. Those are averages, and some people hold. In a 2024 follow-up of a Danish trial, people who had a year of supervised exercise regained 6 kg less in the year after treatment than people who had a year of liraglutide alone.

In the 4,014 posts we read from people coming off a GLP-1, the ones who said when it came back put it a median of 4 weeks after the last dose, and the ones who said when it eased put that at about 8.5 weeks. That roughly follows how long the drugs take to clear, and not everyone gets it. Logging your meals while it's loud shows you what's actually going in. Our guide on hunger after stopping has the full timeline.

Leanos sets your calorie target from your sex, age, height, weight and daily steps. It starts 500 calories under maintenance, which suits losing. To hold your weight, add those 500 back in Settings or ask the coach to change it, then give it two or three weeks of weigh-ins before you adjust again. Your protein target comes from your lean mass, since protein keeps you full and protects muscle.

No. Starting, stopping, tapering and going back on are decisions for you and your prescriber, and Leanos gives no dose advice. It covers everything around them: what you eat, protein, steps, lifting, sleep and your weight trend. If you're stepping down, that record is something concrete to show your prescriber.

You use it to stay on the habits you sign up for at install (daily steps, strength sessions, sleep, protein and a daily check-in) and off chips and cookies, fast food and sugary drinks. Ask it anything and it answers from your own meals, lifts and weight, like how this week compares with last week and what changed. It also explains why each habit matters, like why lifting protects your muscle while your weight holds.

You get 14 days free on the annual plan, then it's $149.99 USD a year. The monthly plan is $19.99 USD a month with no trial. Cancel in your iPhone's settings at least 24 hours before the trial ends and you aren't charged.

Logging a meal takes a few seconds. Take a photo and vision AI lists each food with its calories and protein, and you can adjust any portion before you save. You can also type what you ate. Add weights, like 200g of chicken breast, and common foods are counted from a USDA nutrient table, so the same entry gives the same number every time. A photo can't show the oil in the pan or what a portion weighs, so typing with weights is the more accurate way to log.

Your data lives on your iPhone and in your own private iCloud when you're signed in, so it carries over to a new phone. Leanos keeps no copy on its servers. Your messages to the coach, the meals you log, and your check-in photos go to Anthropic to generate replies, estimates, and photo reads. You can turn photo analysis off in Settings, and Anthropic's API terms say it doesn't train on that data. The privacy policy lists every service involved.
