You know that daydream we all have from time to time? The one that goes something like this: You can eat chocolate, cheese, and pasta all day long, paired with regal glasses of red wine--and never gain a single ounce. Well, science says that dream might just be a reality--at least when it comes to the wine.
It all comes down to a polyphenol called resveratrol, which is found in fruits like berries and grapes. When given a high-fat diet with a concentration of this polyphenol equivalent to 12 ounces of fruit per day for humans, mice gained about 40 percent less weight than their counterparts not receiving resveratrol in a 2015 study. This effect was due to the polyphenol’s ability to transform white fat (the dangerous kind) into beige fat (a mixture of white and brown fat, a good type that actually boosts metabolism).
Though the findings were in mice, the polyphenol could potentially help humans on a balanced, healthy diet lose weight by activating this same change in fat. Since the mice were placed on high-fat diet to test protection against weight gain, a healthy diet paired with this polyphenol could actually help you drop a few.
But you’re not out in the cold if you don’t pour yourself a glass daily. Resveratrol is found in many fruits, including blueberries, strawberries, apples, grapes, and raspberries. Snacking on 12 ounces a day--or about 2 to 3 servings--will boost your intake levels to the same as the mice who saw their fat go through this healthy “browning” process.
