Do I need to follow a specific diet while on GLP-1 medication?

Back to FAQs

Defy Medical does not require a specific diet plan as part of GLP-1 therapy, but a healthy diet and regular exercise can improve your results.

GLP-1 medications slow gastric emptying and reduce appetite, which naturally encourages patients to eat less. However, the quality of what you eat still matters.

Patients who pair GLP-1 therapy with a nutrient-dense diet tend to lose more weight, preserve more lean muscle mass, and feel better throughout treatment than those who rely on medication alone.

A few general actions that support GLP-1 therapy include:

  • Prioritize protein – Adequate protein intake helps preserve lean muscle mass during weight loss, which is important for long-term metabolic health.
  • Focus on whole foods – Vegetables, lean proteins, healthy fats, and complex carbohydrates support stable blood sugar and sustained energy. Avoid overly processed foods if possible.
  • Eat slowly and mindfully – Because GLP-1 medications slow digestion, eating too quickly or too much at once can worsen side effects like nausea and discomfort.
  • Stay hydrated – Drinking enough water supports overall health and can help manage common side effects.
  • Limit alcohol – Alcohol adds empty calories and can interfere with weight loss progress.

If you have specific dietary needs or health conditions that affect your diet, discuss them with your provider so your treatment plan accounts for them.
