Consistent water intake throughout the day, not just when thirsty, is one of the most practical ways to prevent dehydration on GLP-1 medications, since appetite suppression can blunt normal thirst signals along with hunger.

Fiber intake, commonly targeted around 25 to 30 grams daily, supports digestive regularity on GLP-1 medications and is one of the most practical tools for managing constipation, a common side effect of slowed gastric motility.

Many people on GLP-1 medications report reduced interest in alcohol, an effect with real research behind it, while also often experiencing lower alcohol tolerance than before starting treatment.

Adequate protein intake, generally 1.2 to 2.0 grams per kilogram of body weight daily, is the most consistently recommended dietary priority for people on GLP-1 medications, since reduced appetite makes it easy to fall short without realizing it.

Sodium, potassium, and magnesium losses from GI side effects like vomiting and diarrhea can accumulate quickly on GLP-1 medications, and rapid weight loss itself can increase electrolyte needs, making these minerals worth tracking, not just water.
