Why Protein and Fiber Matter During GLP-1 Weight Loss

Protein and fiber are two nutrients worth paying attention to during GLP-1 treatment. Both support important aspects of health, although they serve different functions.


Protein Supports Muscle Health

During weight loss, some loss of lean tissue can occur alongside fat loss. Adequate protein, combined with appropriate resistance exercise, can help support muscle maintenance.

Sources include eggs, fish, poultry, dairy products, soy foods, and legumes.


Fiber Supports Digestive Health

Fiber helps support regular bowel movements and a healthy gut. Sources include oats, beans, vegetables, fruit, nuts, and whole grains.

However, increasing fiber too quickly can worsen gas and bloating. Some people also find certain high-fiber foods difficult to tolerate while experiencing medication-related digestive symptoms.


How to Include Both

Try oatmeal with Greek yogurt and berries, chicken with brown rice and vegetables, or tofu with quinoa and cooked vegetables.

Start with portions you tolerate comfortably, and increase fiber gradually while maintaining adequate fluid intake.

The takeaway: Protein and fiber can complement each other, but neither needs to become a rigid rule. Your intake should be personalized to your needs and digestive comfort.

Consult a registered dietitian for individualized recommendations, particularly if you have kidney disease or a gastrointestinal condition.
