Food & protein

Small, high-protein meals when your appetite is low

When you're only hungry for a few bites, a full plate can feel like a chore. Guidance for people on GLP-1 medications leans toward smaller meals, more often, with protein first. Here is what that means in practice, and how much protein common foods actually hold.

Smaller and more often

The 2025 joint nutrition advisory suggests smaller, more frequent meals — and, in the first days of treatment, avoiding fatty or high-fibre foods — to help with stomach side effects. It notes that small, frequent meals may work when hunger and food interest are low, that vomiting is more likely after large meals, and recommends regular small meals at consistent times^[1].

Protein first

The same advisory suggests eating protein-rich foods first in a meal, so that if you fill up quickly, the protein has already been eaten^[1].

How much protein is in common foods

Values below are from Health Canada's nutrient tables, except Greek yogurt, which is from USDA FoodData Central^[2][3].

Putting small plates together

Using those values: a 170 g Greek yogurt with 30 mL of peanut butter is about 24 g of protein; two hard-boiled eggs with 250 mL of milk is about 21 g; 75 g of canned tuna on crackers is about 19 g before the crackers^[2][3]. These are examples of the arithmetic, not a meal plan for you.

Fluids still matter

The advisory notes that dehydration from severe nausea, vomiting or diarrhea can cause acute kidney injury, and recommends ensuring adequate fluids^[1]. If you can't keep fluids down, contact your prescriber rather than pushing food.
