Why it is filling
Lentils bring fiber and plant protein, and the broth and vegetables add a lot of volume for few calories: it is a dish that fills you up slowly. The fiber helps keep you regular, which matters because constipation is common on GLP-1 medications. Legumes give some people gas, which can be more noticeable when the stomach empties slowly.
In numbers, each serving has 14 g of protein and 13.4 g of fiber, with an energy density of 83 kcal per 100 g of the dish. In the satiety index by Holt and colleagues (1995), the foods that were most filling per calorie were those with more protein, fiber, and water and less fat.
If your appetite is small
- It makes four servings: freeze whatever you won’t eat within 3 days in single containers.
- Blended until smooth, it often goes down more easily when you have nausea or little appetite.
- For more protein, top each bowl with a chopped hard-boiled egg or a few cubes of cooked ham.
