Flavonoid phytonutrients (found concentrated in citrus, berries, red onions, beans, green tea, grapes, and cocoa) may boost metabolism enough to significantly slim one’s waistline.
This completes my seven-part video series on this fascinating phenomenon. I began by reviewing the balance of evidence on why nuts don’t tend to contribute to weight gain in Nuts and Obesity: The Weight of Evidence. I then introduced two theories on Solving the Mystery of the Missing Calories, both of which were put to the test in a study on peanut butter, Testing the Pistachio Principle. Next came Testing the Dietary Compensation Theory, an elegant study using walnut smoothies, followed by the big reveal in Testing the Fat-Burning Theory. But why might nuts help you burn more fat? Arginine is one possibility (see Fat Burning Via Arginine), and today’s video on flavonoids presents another. For more on flavonoid phytonutrients, see Phytochemicals: The Nutrition Facts Missing From the Label. For a comparison between fruit juices, see Best Fruit Juice, along with a video on putting that knowledge into practice: Pink Juice with Green Foam. Which beverage has the most antioxidants, though? See Better Than Green Tea. And what about juiced vegetables, such as carrots and beets? See Benzene in Carrot Juice, and an entire series starting with Doping With Beet Juice. And for more on the wonders of Concord grapes (yum!), see Repairing DNA Damage; and Plant-Based Diets and Cellular Stress Defenses.
