Protein-Rich Foods: Lean meats, fish, eggs, and plant-based protein sources like tofu can aid in muscle development.
Complex Carbohydrates: Foods like sweet potatoes, brown rice, and oats provide energy for workouts, helping build glute muscles.
Healthy Fats: Avocado, nuts, and olive oil contain monounsaturated fats that support muscle growth and add curves.
Vegetables: Fiber-rich vegetables like spinach and broccoli can help with overall body composition.
Water: Staying hydrated is crucial for muscle recovery and growth.
Strength Training: Pairing a nutrient-rich diet with targeted glute exercises is essential for desired results.

Remember that a balanced diet and regular exercise are key to achieving a fuller butt in a healthy and sustainable manner.
