Per-medication nutrition guides
Each FDA-approved GLP-1 receptor agonist has a different titration schedule, half-life, and side-effect timing. Nutritional support during initiation and dose escalation is partly drug-specific. These guides are descriptive, not prescriptive: dosing, switching, and titration decisions are between you and your prescribing clinician.
GLP-1 medication comparison: nutritional impact across the class
Side-by-side comparison of semaglutide, tirzepatide, liraglutide, dulaglutide, and exenatide on the dimensions that matter for nutritional planning. Magnitude of appetite suppression, dose schedule rhythm, side-effect profile, and the practical implications for protein, hydration, and micronutrient planning.
Compounded semaglutide and nutrition: what to know
GLP-1 Nutrition takes no position on whether compounded semaglutide should be used. This article addresses the nutritional considerations that apply to patients who are using compounded formulations, with explicit reminders that compounded medications are not FDA-approved and that all clinical decisions require involvement of a prescribing clinician.
Tirzepatide nutrition guide: Mounjaro and Zepbound
How tirzepatide nutritionally compares with semaglutide. SURMOUNT body-composition findings. Protein, side-effect, hydration, and micronutrient considerations specific to the dual-agonist mechanism.
Dulaglutide nutrition guide: Trulicity
Dulaglutide (Trulicity) is FDA-approved for Type 2 diabetes only, not for chronic weight management. Weight loss is typically smaller than with semaglutide or tirzepatide. Practical nutritional considerations for diabetes-focused GLP-1 use.
Semaglutide nutrition guide: Ozempic and Wegovy
What changes nutritionally when a patient is initiated and titrated on once-weekly semaglutide. Protein adequacy, side-effect-driven undereating, micronutrient considerations, hydration patterns, and the practical questions patients commonly bring to a dietitian appointment in the first 6-12 months.
Liraglutide nutrition guide: Saxenda and Victoza
Liraglutide is a once-daily GLP-1 receptor agonist with a longer clinical track record but typically smaller weight-loss magnitude than semaglutide or tirzepatide. Practical nutritional considerations for daily-injection rhythm, side-effect timing, and protein/micronutrient adequacy.
Oral semaglutide nutrition guide: Rybelsus
Once-daily oral semaglutide (Rybelsus) is FDA-approved for Type 2 diabetes. The medication's absorption is highly food-dependent and requires strict morning fasting around the dose. This article covers the timing requirement, side effects, and nutritional planning.
