Protein shakes in, yoghurt and eggs out: what changes in the food diary of members using GLP-1 medication
Key findings
ParrotPal members who told us they use GLP-1 medication logged protein shakes, bars or protein milks on 33.6% of their logged days, March to August 2026, against 26.9% for members who don’t. They logged Greek yoghurt, skyr, cottage cheese, quark or egg whites on fewer days (16.7% against 21.2%). Source: ParrotPal anonymised food diaries, more than 500 members using GLP-1 medication.
Members who told us they use GLP-1 medication logged a protein shake, bar or protein milk on about 1 in 3 of their logged days (33.6%), against about 1 in 4 for everyone else (26.9%). Some everyday protein foods turned up less often.
33.6%of logged days had a protein shake, bar or protein milk
Days with each food group
Share of logged daysEggs appeared on 31.1% of logged days against 36.8%, and Greek yoghurt, skyr, cottage cheese, quark or egg whites on 16.7% against 21.2%. The shift to protein products showed in women (30.9% against 23.7%) and men (41.6% against 32.4%).
Alcohol was about the same: logged on 8.0% of days against 8.8%, and about half of each group logged a drink at least once (50.4% against 56.8%). If you have questions about alcohol and your medicine, ask your prescriber or pharmacist.
Crisps, sugary drinks and chain food were about the same in both groups. Sweet treats were close too (39.7% against 41.6% of days).
Plants slipped a little: fruit on 48.2% of days against 51.1%, vegetables on 57.4% against 60.3%. Logged fibre was a median 13.3 g a day against 15.1 g, and members using GLP-1 medication logged fewer items a day (8 against 9).
Food groups are matched from the names members logged, so they’re approximate. We don’t measure ultra-processed food. This shows what members logged, not why, and not that any medicine caused a change.
What this means
Protein drinks and bars are an easy way to get protein in when portions are small, and the diaries show members reaching for them. Everyday foods such as yoghurt, skyr and eggs can do the same job; the label tells you how much protein a portion gives.
What the research says
A 2025 joint advisory from four US nutrition and obesity societies notes that higher protein targets, such as 1.2–1.6 g per kg a day, have been proposed during active weight reduction (or an absolute 80–120 g a day), and that protein intake in adults should not fall below 0.4–0.5 g per kg a day.

UK government guidelines say adults should aim for 30 g of fibre a day.

Method in brief. ParrotPal members’ anonymised food diaries, 1 March to 31 August 2026, members in every country. A counted day has 3 or more entries and 300 to 6,000 kcal; members need 7 or more counted days; deleted entries don’t count. GLP-1 use is each member’s latest answer to our sign-up question; “not using it” means they said they weren’t using any. Weight is each member’s median weigh-in in the window. A food group counts on a day if a member logged it at least once that day. Each member counts once (the share of their own logged days), then shares are averaged. more than 500 members using GLP-1 medication.
Aggregates only: every group shown has 50 or more members and no share rests on fewer than 10. Patterns in what members logged, not causes. who’s counted · the 50/10 rule · logged isn’t eaten.
Questions people ask
What do people using GLP-1 medication log in their food diaries?
In ParrotPal diaries, March to August 2026, members who told us they use GLP-1 medication logged protein shakes, bars or protein milks on 33.6% of their logged days, against 26.9% for other members.
Do people using GLP-1 medication log less alcohol?
Not in our data: alcohol appeared on 8.0% of their logged days against 8.8% for other members. Questions about alcohol and your medicine are for your prescriber or pharmacist.
