How much protein do people on Ozempic aim for?

Published guidance for people losing weight on GLP-1 medications commonly cites 1.2–1.6g of protein per kg of body weight per day to help preserve lean mass, but individual targets vary; your prescriber or dietitian sets yours. Protein Pal’s calculator has a GLP-1 mode if you want a starting estimate to discuss with them.

Why do these bars have so little sugar?

Not because of a sugar cap (there isn’t one) but because the protein density requirement leaves no room for it: a bar spending calories on sugar cannot reach 10g of protein per 100 calories. With a much smaller appetite, foods high in sugar crowd out protein without helping satiety, and the standard screens them out on their own numbers. Bars on this list are typically sweetened with stevia, allulose, sucralose or sugar alcohols instead; each product page lists exactly which, and sugar is shown for every bar.

Why do sugar alcohols, fiber and bar size affect the ranking?

Among bars with equally strong protein per calorie scores, we rank bars without certain sugar alcohols (maltitol, sorbitol, xylitol, isomalt, mannitol, lactitol) first, then bars with more fiber, then smaller bars. To be clear about the evidence: a single bar contains well below the doses where studies find symptoms in healthy adults. The ordering is a precaution for sensitive people (these sugar alcohols are excluded from low FODMAP diets used for irritable bowel syndrome, and people with sensitive digestion report symptoms at lower doses), for anyone eating several sugar free products a day, and because GLP-1 medications commonly cause gastrointestinal side effects of their own; no study has tested the combination directly. Erythritol is not penalised because it is mostly absorbed and excreted unchanged. Fiber contributes to satiety, and a smaller bar is simply easier to finish when appetite is suppressed. Bars containing these sugar alcohols still appear, clearly marked, and the research is linked at the bottom of this page.

Are these bars easier to tolerate on days with nausea?

We can’t make tolerance claims; that varies person to person and is a conversation for your care team. What we can tell you is what’s on the label: some users prefer to check the sugar alcohol content of a bar, which is listed on every product page here, since sugar alcohols like maltitol are known to cause gastrointestinal discomfort in larger amounts (research linked below).

Best Protein Bars for Ozempic Users

Ozempic (semaglutide) slows digestion and shrinks appetite, so most of what you eat has to earn its place. The bars below meet the same verified standard as all our GLP-1 bar rankings: at least 10g of protein per 100 calories and at least 10g per bar, at most 200 calories, and a complete protein, ordered by protein per calorie, then fiber, then smaller bar size (less to finish on a small appetite), with certain sugar alcohols marked where present. This page focuses on what is specific to semaglutide: the side effects that shape which bars people actually finish, what changes on Wegovy, and eating around your weekly shot. Every value is transcribed and verified from the manufacturer’s nutrition label.

Bars marked “contains maltitol” include a sugar alcohol some people prefer to avoid. What are sugar alcohols?

Note: This page is nutrition information only, not medical advice. Nothing here is a claim that any product treats, prevents or reduces side effects of any condition or medication. Always follow your clinician’s guidance on nutrition while taking GLP-1 medications.

Eating around your weekly shot

Many people report appetite is weakest, and nausea most likely, in the first day or two after injecting. On those days users commonly keep portions small, eat protein first and avoid rich or very sweet foods. A smaller high protein bar you can actually finish beats a bigger one you abandon, which is why bar size is one of our tiebreakers. If nausea disrupts eating for days at a time, raise it with your prescriber.

Why these criteria?

Ozempic (semaglutide) slows gastric emptying and reduces appetite, so many users find they eat far smaller portions. Clinicians commonly advise prioritising protein to help preserve lean mass while losing weight. The protein density requirement (at least 10g per 100 calories, the same bar that earns our top Protein Score) keeps out bars that are dessert with a protein claim, since a sugary bar cannot pass it on its own numbers, and the 200 calorie cap keeps every bar a realistic portion on a small appetite. Bars carrying 8g or more of fat are marked "higher in fat" rather than excluded, since fat slows a stomach the medication has already slowed.

Does this list apply to Wegovy?

Yes. Wegovy is the same medication as Ozempic (semaglutide), approved at different doses for weight management rather than type 2 diabetes. The same high protein criteria apply, so this list is equally relevant if you take Wegovy.

What about Mounjaro and Zepbound?

Mounjaro and Zepbound are tirzepatide, a different medication with a similar effect on appetite. The nutrition criteria on this page don’t depend on which drug you take (they describe the bar, not the medication), so the list is the same. We track the label data; your care team tracks the rest.

How this ranking works

Every nutrition value is transcribed from the manufacturer’s published nutrition label and verified by hand, with no third party food databases.
Product lines are ranked, not individual flavours, so one product’s 20 flavours can’t fill the list. Each entry shows its best scoring flavour.
A maximum of two lines per brand keeps the list diverse.
Labels that don’t state sugar or fiber are treated as unknown (never as zero) and are excluded from sugar and fiber rankings.
