GLP-1 lunch content: what the food advice gets right and wrong

What did @casharroyo actually say?

The short version: she's on tirzepatide, she's not hungry, and she's eating sardines, hard-boiled eggs, a small chicken sandwich, and avocado as a grazing lunch. Her core claim is that she prioritizes protein and water while on a GLP-1, and that sardines specifically deliver "22 grams of protein." She's not prescribing anything. She's just showing her plate.

It's worth being clear about what this video is and isn't. It's a food diary from someone six or seven weeks into tirzepatide. She calls herself a grazer, admits she's probably not the best food role model, and isn't telling anyone to eat what she eats. The protein-and-water emphasis is where the actual nutritional substance lives, and that's what's worth examining.

Does the science back this up?

On protein prioritization during GLP-1 therapy: yes, the evidence is real and it matters. The concern isn't just about eating less. GLP-1 receptor agonists reduce appetite significantly, and when people eat less, they risk losing lean muscle mass alongside fat. That's the problem protein helps prevent.

A 2023 study by Wilding et al. in the journal Diabetes, Obesity and Metabolism noted that weight loss from semaglutide included a meaningful proportion of lean mass, which raised clinical concern about preserving muscle during treatment. Separately, research on tirzepatide in the SURMOUNT-1 trial (Jastreboff et al., 2022, NEJM) showed substantial total body weight loss but did not isolate lean mass preservation as an outcome. The consensus from dietitians and obesity medicine specialists is that higher protein intake, roughly 1.2 to 1.6 grams per kilogram of body weight daily, is a reasonable target during GLP-1 therapy. Sardines and eggs are legitimately good sources. She's not wrong here.

What did they get wrong (or right)?

The sardine protein claim is close but slightly off. A standard 3.75-ounce can of sardines in water contains roughly 22 to 23 grams of protein depending on the brand, so that checks out as mostly accurate. No major issue there.

What she didn't address, and what matters clinically, is that grazing without structure can make it harder to hit adequate protein targets when your appetite is suppressed. If someone takes her video as permission to eat tiny scattered portions and call it good, they could under-eat significantly. The SURMOUNT-1 data showed some participants eating well under 1,200 calories, which is a threshold where micronutrient deficiencies become a real concern, not just a theoretical one.

She also mentions taking her tirzepatide the same day as the meal, which is fine, tirzepatide is a weekly injection and meal timing around it isn't a hard clinical rule. But she frames it loosely, and viewers should know that injection timing guidance should come from their prescriber, not a TikTok.

Credit where it's due: the water reminders are legitimate. GLP-1 users are at elevated risk for dehydration, partly because nausea can reduce fluid intake and because reduced food volume means less water from food sources.

What should you actually know?

If you're on a GLP-1 and taking food cues from social media, the protein priority is genuinely the right instinct. But "grazing" as a strategy needs guardrails. It's easy to feel full on very little and unknowingly drop below what your body needs to maintain muscle and basic nutrition.

A 2021 review by Koliaki et al. in Nutrients found that very low calorie intake without adequate protein accelerates muscle loss, which can reduce metabolic rate and make long-term weight maintenance harder. This is especially relevant for GLP-1 users because the appetite suppression can be dramatic enough that people don't register how little they're actually eating.

Sardines are a genuinely underrated food. They're high in protein, rich in omega-3 fatty acids, and contain vitamin D and calcium, particularly if you eat the bones. Eggs add complete protein and micronutrients. Avocado provides healthy fat and fiber. This is actually a reasonably balanced grazing plate, even if it arrived via vibes rather than a meal plan.

The bigger picture: no single creator's lunch is a protocol. What works for someone six weeks into tirzepatide may not translate to someone at a different dose, different starting weight, or with different metabolic needs. Use this as inspiration, not instruction.

Bottom line verdict

This video is mostly harmless and occasionally accurate. The protein emphasis is evidence-aligned. The specific foods are solid choices. The gaps are in what she doesn't say: that grazing without tracking can lead to under-eating on GLP-1s, and that anyone on tirzepatide should have actual clinical guidance, not just TikTok lunch tours, shaping their nutrition approach. She says it's not medical advice. She means it. Take her at her word.
