Tips for GLP-1 appetites

• Not the gentlest option on a rough stomach day — better suited to when appetite and digestion feel normal.
• Go lighter on the strong aromatics (garlic, onion, spice rub) if smells are a trigger right now.
• At 19g of protein a serving, this alone gets you a meaningful chunk of the way to a daily 80–120g protein target.
