Follow the manufacturer's instructions to preheat your waffle maker.
In a mixing bowl, combine the Herbalife Formula 1 Nutritional Shake Mix, whole wheat flour, baking powder, and salt. Mix well.
In a separate bowl, whisk together the milk, melted butter or oil, and egg until well combined.
Gently combine the wet ingredients with the dry ingredients until they are just mixed together. Do not overmix; a few lumps are okay.
Let the batter rest for about 5 minutes to allow the ingredients to hydrate.
Grease the preheated waffle maker with a light coating of oil or cooking spray.
Pour the batter onto the hot waffle maker, following the manufacturer's instructions for the desired amount of batter.
Close the waffle maker and cook until the waffles are golden brown and crispy, typically 3-5 minutes.
Use a spatula to remove waffles carefully form from the waffle maker.
Serve the Herbalife waffles warm with your favorite toppings like fresh fruits, nuts, honey, or yogurt.
