Does Victoza take away your appetite?
Bottom line
Yes. Decreased appetite is listed among the common adverse reactions on Victoza's own FDA label, published 2025-10-14. It clusters in the days after each dose increase and settles in between, so the pattern is a few rough days per step rather than one continuous stretch.
No clinician has reviewed this page. Every clinical statement on it is drawn from the FDA label or the trial cited beside it, and every price carries the date it was verified — but that is sourcing, not medical review, and the two are not the same thing.

Does Victoza take away your appetite?
Yes, and it is on the label rather than only in reports: decreased appetite appears among the common adverse reactions in Victoza's FDA prescribing information, published 2025-10-14. Listed means it was seen often enough in the trials to be printed, not that everyone gets it. Yes, and that is the drug working rather than a side effect in the usual sense — the label lists it among the common reactions because it is measured as one, but reduced appetite is the route by which every one of these medicines produces weight loss. It becomes a problem at the point where intake falls below what a body needs, which is easy to miss precisely because hunger is no longer the signal. It clusters in the days after each dose increase and settles in between, so the pattern is a few rough days per step rather than one continuous stretch. What helps, in the order worth trying: writing down what you actually ate for three days. Almost nobody estimates this correctly once appetite is suppressed; protein at every meal, because a smaller total intake makes composition matter more than it did; eating on a schedule rather than on hunger, at least while the dose is climbing; raising it if you cannot finish small meals, are losing faster than about a percent of body weight a week, or feel weak. Those are reasons to review the dose. It stops being ordinary at a specific line: being unable to keep food or fluid down at all, weight falling far faster than expected, or fainting. Also new hair loss with fatigue, which usually means intake has been well under for some weeks.
Why Victoza does this
Yes, and that is the drug working rather than a side effect in the usual sense — the label lists it among the common reactions because it is measured as one, but reduced appetite is the route by which every one of these medicines produces weight loss. It becomes a problem at the point where intake falls below what a body needs, which is easy to miss precisely because hunger is no longer the signal.
What actually helps
- 1Writing down what you actually ate for three days. Almost nobody estimates this correctly once appetite is suppressed.
- 2Protein at every meal, because a smaller total intake makes composition matter more than it did.
- 3Eating on a schedule rather than on hunger, at least while the dose is climbing.
- 4Raising it if you cannot finish small meals, are losing faster than about a percent of body weight a week, or feel weak. Those are reasons to review the dose.
Approved for type 2 diabetes rather than for weight. Saxenda is the same molecule at a higher dose with a weight-management approval.
When to stop reading and call someone
Being unable to keep food or fluid down at all, weight falling far faster than expected, or fainting. Also new hair loss with fatigue, which usually means intake has been well under for some weeks.
Separately, Victoza carries a boxed warning. In both sexes of rats and mice this molecule caused thyroid C-cell tumours at clinically relevant exposures. Whether it does so in people is unknown, and the label carries that as a boxed warning. It is contraindicated outright with a personal or family history of medullary thyroid carcinoma or MEN 2.
