The typical serving is a common amount used for the math, not a recommendation. Ounces and cups are rounded US equivalents; the values come from the database entry cited in the sources.

Satiety

Calculation: 1 (base) + 1 (low energy density: 155 kcal/100 g) + 2 (protein: 8.1 g/100 kcal) + 0 (fiber: 0.0 g/100 kcal) + 1 (solid food with 74.6 g of water) = 5.

The 1 to 5 score is our own estimate: it starts at 1 point, adds points for low energy density, for protein and fiber per 100 kcal, and for the water in solid foods, and subtracts points for drinks with calories. It is useful for comparing foods with each other; it is not a measurement in people.

What to keep in mind on a GLP-1 medication

High in protein
It has at least 10 g of protein per 100 g and 6 g per 100 kcal. Protein is the most filling nutrient per calorie and helps preserve muscle mass during weight loss, which matters especially when a GLP-1 medication reduces your appetite.
Easy to digest
It is a soft or low-fat food that many people tolerate well when they feel nauseous or get full quickly. This is an editorial judgment based on common patient guidance, not a measurement: everyone tolerates foods differently.
Nutritious in small servings
It provides protein, healthy fats, or other nutrients in a small volume. That is practical when you eat little and every bite needs to count.

It is an estimate based on its composition, not a measurement in people.

How does hard-boiled egg sit with nausea from a GLP-1 medication?

Based on our tags, this is what matters about hard-boiled egg on a GLP-1 medication. “High in protein”: plenty of protein per calorie; protein helps preserve muscle mass when you eat less. “Easy to digest”: a soft or low-fat food that many people tolerate well when they feel nauseous or get full quickly. “Nutritious in small servings”: a lot of nutrition in a small volume, which is practical when you eat little. These are general guidelines, not medical advice: everyone tolerates foods differently.

What counts as a normal serving of hard-boiled egg?

We use 50 g (2 oz) as a typical serving. That amount provides about 78 kcal, 6.3 g of protein, and 0 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
