Nutrition on GLP-1s: protein, hydration, fiber, and muscle retention.

A practical support guide for readers who want the boring-but-important plan behind the medication conversation: protein, resistance training, constipation prevention, hydration, and follow-up.

Why nutrition gets harder

When appetite drops, nutrition quality can improve or deteriorate. Some readers eat less ultra-processed food; others simply undereat protein, fluids, fiber, and micronutrients. The difference is planning.

Protein and muscle retention

Weight loss is not automatically fat loss. A support plan should discuss protein intake, resistance training, activity tolerance, and whether rapid loss is creating fatigue, weakness, or other concerns.

Hydration, fiber, and GI comfort

Constipation, reflux, nausea, and dehydration can derail adherence. Hydration, slower meals, fiber strategy, and clinician-guided dose adjustments are practical issues, not wellness fluff.

What to track

Readers can bring weekly notes to a clinician or dietitian: protein consistency, fluids, bowel changes, nausea triggers, strength training, body composition concerns, and whether the plan still feels sustainable.
