Mixing whey protein into your morning smoothie is a surefire way to jump-start metabolism and increase fat burning. It contains an amino acid (leucine) that triggers muscle cells to use energy more efficiently. Research in The American Journal of Clinical Nutrition revealed that this effect can raise the body’s ability to burn fat for fuel by 18 percent and increase calorie expenditure by 25 percent for up to 5.5 hours.
An added bonus: Whey is incredibly filling. After drinking a whey smoothie, people in a study at the United Kingdom’s University of Surrey experienced a 68 percent increase in two key appetite-suppressing hormones. Whey’s satiating effect stayed with them until their next meal, during which they consumed 19 percent fewer calories than study subjects given a shake made with another form of protein.
Here’s the yummy recipe:
1 scoop (1/2 cup) whey protein powder, like Source Naturals True Whey Premium Powder, $24 for 16 oz., amazon.com
1 1/2 cups frozen blueberries
1 cup vanilla rice milk or skim milk
3/4 cup plain yogurt
In blender, combine all ingredients. Blend until smooth.
