Key Takeaways
- On a GLP-1 the food problem turns around. Eating less stops being the hard part, and getting enough of the right things into a small appetite becomes it. Almost every food app on the store shelf was built for the opposite problem.
- The eating side is inside the prescription, not next to it. The FDA label for semaglutide says the drug is indicated in combination with a reduced calorie diet and increased physical activity.
- Protein and fluids are floors to reach, not ceilings to stay under. The same label tells patients to drink fluids to reduce the chance of dehydration, because nausea, vomiting and diarrhea are among the most common adverse reactions.
- The most useful field on a GLP-1 is one that almost no app has: how the meal sat afterwards. That note, not the calorie total, is what changes next week's shopping list.
- BeCute is being built around those fields. It is in early access, the early list is free, and there is nothing to install today.
The question usually arrives in a form like this. I am on a GLP-1, I am not hungry, I know I am not eating well, and I do not know what to put on my phone. It sounds like the question a person on a diet asks, and it is not, because the thing you are trying to control has already been controlled for you.
This page does not rank apps. Rankings go stale in a season and the right pick depends on what your clinician asked you to watch. What follows is the part that stays true: why a GLP-1 breaks a normal food tracker, what is actually worth logging, a checklist you can run in an app store in a few minutes, and a one-week test that settles it. There are no weight-loss numbers on this page on purpose. Anyone quoting you a result they cannot source is selling something.
Why the food problem inverts on a GLP-1
A calorie tracker is a device for resisting appetite. Every design decision follows from that: a daily budget, a bar that fills, a warning when you go over, a streak for staying under. On a GLP-1 the appetite is already handled, often more thoroughly than you wanted, and every one of those decisions now points the wrong way.
| What a calorie app is built for | What a day on a GLP-1 looks like |
|---|---|
| You want to eat more than you planned | You have to talk yourself into eating at all |
| The target is a ceiling to stay under | Protein and fluids are floors to reach |
| Every day has roughly the same shape | Some days are two small meals and that is the whole day |
| A meal is either eaten or not eaten | Half a portion left on the plate is the normal case |
| Nothing records how the food felt afterwards | How a meal sat decides whether you ever cook it again |
None of that means a tracker is useless. It means the thing you need it to do has moved, and the app that wins is the one that moved with it.
What the label and the NIH actually say
Before the app question, four statements from first-party sources are worth having in front of you, because they define the job.
The food plan is part of the treatment. The FDA prescribing information for semaglutide states that it is indicated in combination with a reduced calorie diet and increased physical activity, and the dosage section repeats the instruction to administer it in combination with a reduced-calorie diet and increased physical activity. The eating side is not an optional extra somebody on the internet added. It is written into the label.
Digestion itself changes. The same label states plainly that the drug delays gastric emptying, and lists nausea, diarrhea, vomiting, constipation and abdominal pain among the most common adverse reactions. That is why the meal you loved in March can be unbearable in September, and why a log with no field for it is throwing away the most useful thing you learned that day.
Fluids get an explicit instruction. The medication guide in that label tells patients that diarrhea, nausea and vomiting may cause a loss of fluids, and that it is important for you to drink fluids to help reduce your chance of dehydration. Water is the one thing on this page that has a named place in the prescribing information. Most food apps treat it as a decorative widget.
The habit outlives the prescription. The National Institute of Diabetes and Digestive and Kidney Diseases is blunt on both ends of it: medications do not replace physical activity or healthy eating habits and work best when combined with a lifestyle program, and you probably will regain some weight after you stop taking weight management medication. Whatever you learn about your own eating while the medicine is doing the heavy lifting is the part you keep afterwards. That is an argument for keeping a log at all, and for being able to take it with you.
What to track instead of calories
Four things, in this order.
Protein. When the volume of food falls, the composition of what fits inside it is the whole game. Set the target in grams, not as a share of calories, because a share of a shrinking number shrinks with it. Where the published ranges come from, and how to turn one into a per-meal figure, is a separate subject that we covered in how to choose an app for a high-protein target. Bring the number your clinician or dietitian gave you and make the app display it.
Fluids. In the same screen as the food, not in a different tab with a cartoon glass. The label asks for it by name.
How the meal sat. One tap, three states, immediately after eating: fine, heavy, no. Nothing else you record has this much value later, because it is the only field that tells you what to cook next week. If you keep a list of foods that reliably go down easily, you have solved most of a bad day in advance.
When you ate, not what is left of a budget. On a GLP-1 the useful question at three in the afternoon is what has gone in so far and whether there is an eating window left today, not how many calories remain. An app that answers only the second question is answering a question you no longer have.
Notice what is missing from that list: a calorie total. Keep it if your clinician asked for it. Do not make it the number the app shouts at you, because on this medication it is the number you have the least trouble with.
The checklist: what a GLP-1 app has to do
Nine things. The first four decide whether the app is usable at all here.
- A protein goal in grams, set by you. Not derived from a calorie target, not locked behind a subscription, not silently recalculated when your intake drops.
- A per-meal view you can act on during the day. You need to see at lunchtime that breakfast came in low, while lunch can still fix it. A pie chart at midnight is a report on a day you can no longer change.
- Fluids logged next to food. One screen, one glance, no separate app.
- A tolerance note per meal, and a way to search it later. If you cannot ask the app which dinners went badly last month, it is not keeping the record that matters.
- Partial portions without drama. Half a bowl, three bites, abandoned after two forkfuls. All of these need to be one tap, and none of them should trigger a lecture.
- Repetition made cheap. Appetite that small tends to settle on a handful of tolerated meals. Copy yesterday, save a meal, reuse it at a different size. If logging the same small breakfast takes a minute on day three, you will stop by day ten.
- No punishment mechanics. A low-intake day on a GLP-1 is a side effect, not a moral failure. Streaks that break and red screens that scold will get the app deleted on exactly the day you most needed the record.
- Export, and a summary a clinician can read. Your next appointment is the moment the log pays for itself: here is a week, here is what I could not keep down, here is where protein landed. An app that traps the data is costing you the appointment.
- An honest free tier. Check the one thing before you rely on it: can you set a custom protein goal without paying. Paying is fine. Finding out on day four that the single feature you came for is locked is not.
What is not on the list: photo recognition, coaching, recipe feeds, community. Pleasant, none of them decide whether you hit protein on a day you did not want to eat.
A one-week test
Install one candidate, not four. Seven days, one question each day.
- Day one, setup. Enter your protein goal in grams and a fluid goal. If either needs a subscription, you already have your answer.
- Day two, speed. Log the same small breakfast you logged yesterday, and time it. Anything past twenty seconds is a habit you will not keep on a bad day.
- Day three, partials. Log a meal you did not finish, and then a meal you abandoned. Count the taps and watch what the app says to you about it.
- Day four, tolerance. Try to record how a meal sat, then find that note again tomorrow. If there is nowhere to put it, the app is a calorie counter wearing a different label.
- Day five, the afternoon question. At three in the afternoon, answer inside the app: how much protein has gone in so far, and how much water. Count the taps it took.
- Day six, exit. Export the week and open the file. No export, no long-term memory.
- Day seven, verdict. Look back at the week. Could you hand this to a clinician and have it mean something, and did logging cost you less than a few minutes a day. Both yes, keep it. Otherwise the next candidate.
Red flags
- An app that wants to set your intake target for you while you are on a prescription that already sets it.
- Any promise of a weight-loss figure, on any timeline. That number belongs to a clinical trial and a clinician, not to a screen in an app store.
- Streaks, badges and red warnings on days you ate almost nothing.
- No field for symptoms or tolerance anywhere in the log.
- Supplements or GLP-1 support products sold inside the tracker. The incentive is now pointed away from you.
- No export, and no answer to where the food data comes from.
When an app is not the answer
If your week has settled into a short list of meals you tolerate, a note on your phone will do. Write down the two or three protein anchors you know go down easily, with the portion you actually manage, and build days from them. That is a complete system and it needs no subscription. Our guide to what to eat on a GLP-1 with a reduced appetite covers the food side of that in detail.
A tool earns its place when the week is not settled: when you eat out, when tolerance moves around, when someone else will want to see the pattern, or when you are the sort of person who will not remember on Thursday what happened on Monday. If you want the wider category first, we also looked at what AI meal planner apps actually do, one level above this question.
What BeCute is building
BeCute is being built against the checklist above rather than against a calorie counter. A protein floor you set yourself, fluids on the same screen, one tap for how a meal sat, portions that can be half of something, and logging that stays fast on a day when opening an app is already an effort.
What is not yet true: you cannot install BeCute tonight and run the seven-day test on it. That is exactly why the test is written for whatever you are using now. We would rather show you BeCute doing this well than describe it doing it.
If you want to hear the day it lands, put your email on the early access list. It is free, it is one email, and there is no drip campaign behind it.
FAQ
Do I need a special app on a GLP-1, or will a calorie tracker do?
A calorie tracker will do if you can bend it: set a protein goal in grams by hand, ignore the calorie ceiling, and use the notes field for how the meal sat. Most people stop bending it after a fortnight, because every screen in the app is arguing for a goal that is no longer yours. The test is not the brand, it is whether the app can show you a protein floor and a fluid total during the day.
What should I actually be tracking on a GLP-1?
Protein, fluids, how each meal sat, and when you managed to eat. The FDA label for semaglutide asks for fluids by name and lists nausea, vomiting, diarrhea and constipation among the most common adverse reactions, which is why tolerance deserves a field of its own. Calories are the number you are least likely to have trouble with on this medication.
How do I hit a protein goal when I have no appetite?
Mostly by changing the order and the count, not the size. Whatever you eat first is what actually goes in, so the protein source goes first on the plate. More eating occasions beat bigger ones. Anything drinkable counts, and it counts twice when it carries fluid as well. Keep a short list of protein foods you know sit well and stop negotiating with yourself about the rest. The target itself is a question for your clinician or dietitian, and the published ranges behind it are covered in our article on protein targets and apps.
Should an app set my calorie target while I am on the medicine?
No. The prescribing information for semaglutide says it is indicated in combination with a reduced calorie diet and increased physical activity, which means the eating plan sits with the person who wrote the prescription. An app that overrides that with its own arithmetic is not a tool, it is a second opinion you did not ask for.
What happens to the log when I come off the medicine?
It becomes the useful part. The NIDDK states that you probably will regain some weight after stopping weight management medication, and that developing eating habits and activity may help you regain less. A year of records showing which meals worked for you is the closest thing to a plan you will own on the day the prescription ends, which is also the argument for choosing an app you can export from.
Does BeCute work with GLP-1 medicines?
BeCute is in early access and there is nothing in the app stores to install yet, so the honest answer is that you cannot try it against a GLP-1 today. What we can tell you is what it is being built to do, which is the list above. If you want to be told the day that changes, the early access list is the whole mechanism.
