The GLP-1 Food Certification Standard
GLP-1 medications change how the body handles food. Our certification exists because the nutritional gap that opens up is measurable, common, and fixable at the product level.

When appetite drops, the shortfall usually shows up first in protein, fiber, and key micronutrients — not just in total calories. That's a formulation problem, not a willpower problem, and it's one that food and beverage brands are positioned to solve.
Lean mass is on the line
Roughly a quarter of the weight lost during GLP-1 therapy is muscle, not fat — and that share climbs when protein intake falls short.[1] Clinical advisory groups now recommend 1.2–1.6 g of protein per kg of bodyweight per day during active weight loss, or a practical target of 80–120 g daily.[2]
Delayed digestion changes what "tolerable" means
GLP-1 therapy slows gastric emptying. High-fat, high-viscosity, and high-fiber foods — especially at the evening meal — compound that slowing and are more likely to trigger nausea or bloating. Foods built around lean proteins, cooked or peeled produce, and moderate healthy fats tend to sit better.[3] This is why GLP Certified™ evaluates fiber by type and timing, not just by grams on a label.
30+ million consumers are looking for food built for GLP-1 therapy.[1] Mogna-Peláez P, Guasch-Ferré M. J Nutr. 2026;156:101684.[2] Mozaffarian D, et al. Am J Lifestyle Med. 2025.[3] Gentinetta S, et al. Diabetes Metab Syndr Obes. 2024;17:4817–4824.Eight criteria.
One standard.
Every submission — a finished product, a meal kit line, or a functional ingredient — is measured against the same nutrient-density and tolerability framework, built directly from the peer-reviewed literature on GLP-1 nutrition.
Protein density
≥15g per serving for meals, ≥10g per 100 kcal for meal replacements, ≥8g for snacks where feasible.
Fiber — type & timing
5–8g for daytime use; ≤5g, soluble-favored, for evening or meal-replacement formats.
Energy density
300–600 kcal per serving for meal replacements; 100–300 kcal for snacks.
Fat load & type
Total fat ≤35% of calories; saturated fat held to ≤10% of calories or ≤3g per serving.
Protein quality
Complete or complementary amino acid profile, with source disclosed and leucine content considered.
Micronutrient contribution
Meaningful %DV across vitamin D, B12, iron, calcium, magnesium, zinc, and potassium.
Added sugar & processing
Added sugar capped at 5g or 10% of calories, with minimal processing preferred.
GI tolerability
Viscosity, fat, and fiber are reviewed together — not in isolation — against gastric-emptying impact.
A product can be fiber-rich and still pass with a strong tolerability score if the fiber is soluble, well-portioned, and positioned for daytime use. The reverse is also true: strong nutrient density alone doesn't clear the bar if a product combines high fat, high viscosity, and high fiber into one evening-oriented serving.
From submission to certification
What's eligible
Foods and beverages marketed or reformulated for GLP-1 therapy
Functional ingredients that change a finished product's nutrient density or GI tolerability
Meal replacements, bars, shakes, and portion-controlled meals
What's excluded
Products relying on smaller portions alone, without added protein, fiber, or micronutrient density
Products with unsubstantiated medical or drug-interaction claims
Submissions missing documentation that can't be independently verified
