2. Smoothies
When they are properly prepared, breakfast smoothies are quite filling and nutritious. However, the vast majority of smoothies, especially when referring to bottled ones that are really high in sugar—from flavored yogurts, fruit, and fruit juices, not to mention fro-yo or sherbet, and low in satiating protein and fat, notes Schoenfeld.
The key to a healthy smoothie that lasts you till lunch is to add some protein (you should try protein powders that are made from peas or quinoa) and fat (nut butter, avocado, coconut oil, or milk) for staying energized all day.
