22. Spirulina

Spirulina is a type of blue-green algae that’s loaded with protein and antioxidants. It helps increase feelings of fullness, which can prevent overeating. Even though it’s very low in calories, spirulina provides a wide range of nutrients that support overall health.
You can add spirulina powder to smoothies or shakes for a quick nutrient boost. Its high protein content makes it a great option for supporting muscle growth and promoting weight loss by helping you feel satisfied with smaller portions.
