The Fourth of July is a full-day grill session: burgers, hot dogs, potato salad, watermelon, cold drinks and fireworks. On a GLP-1, the day works best with a light touch — one real BBQ plate, watermelon as the sweet, and water doing the heavy lifting in the heat. The heat matters: on a GLP-1 you dehydrate faster, and dehydration makes everything worse.
Judged with the same framework as the rest of the site — USDA data, protein and fiber first, nausea in mind.

A turkey or chicken dog with a bun is a reasonable choice; a regular beef hot dog is fine in a single serving too. The damage comes from the fourth one plus beer. One dog, protein sides, watermelon for sweet.
GLP-1 drugs blunt the thirst signal, so in summer heat you can dehydrate without noticing. Dehydration amplifies nausea, headache and fatigue. The Fourth of July rule is simple: water, constantly.
Grilled chicken or lean burgers with grilled vegetables — protein, gentle, and not swimming in sauce. Watermelon for dessert is hydration plus sweetness.
