Could water spiked with fat give you a daily energy boost?

FatWater Apparently, oil and water do mix—and some say the combo’s good for your health, too.

Dave Asprey, the creator of the crazy popular Bulletproof enterprise, which includes The Bulletproof Diet and the oft-discussed butter-boosted coffee, just launched his latest product: water spiked with fat.

Essentially a blend of Bulletproof XCT Oil and water, FATwater is meant to hydrate you more quickly and give you an energy bump at the same time—and the product has some serious backing. The launch comes on the heels of an announcement that Bulletproof just received $9 million in funding from Trinity Ventures, an early investor in Starbucks and Jamba Juice. So it’s slated for the wellness-beverage big time.

We talked to Asprey and nutritionists and took some (slightly slimy) sips to learn more about the new-fangled wellness beverage.

The ingredients and claims

FATwater comes in unflavored, berry, orange, or lemon packets that you can mix into water yourself (sold online), or in 16-ounce bottles sold at the Bulletproof Coffee shop and Erewhon Natural Foods in Los Angeles.

Its main “active” ingredients are water and Bulletproof XCT Oil, which is coconut oil that has been triple-distilled to extract medium chain triglycerides (MCTs). The MCTs are then blended with vitamin E, which allows the oil to be permanently suspended in micro-bead form in the water, rather than separating. (It also contains B vitamins, citric acid, natural flavor and color, xylitol, and stevia.)

So how does it work? “We know that the Bulletproof XCT Oil is able to rapidly metabolize energy,” Asprey says. “That way, you’re getting better hydration and getting sustained energy from good fat instead of sugar, which spikes blood sugar.” The energy component is similar to the claim made with Bulletproof Coffee, only with FATwater, each serving is only about 20 calories, compared to hundreds. So, it’s meant to give you a slight energy lift rather than serve as a filling meal replacement.

What experts (and our taste buds) say

“I can see how because you’re drinking the fat, it goes right into the digestive tract, so you might be getting the energy much more quickly,” says Amy Shapiro, RD. “But since there aren’t many studies done on this, I can’t totally speak to the science.”

Shapiro also says that since each serving only has two grams of fat, compared to 14 grams of fat in one tablespoon of coconut oil, she can’t imagine it will give you a huge, noticeable rush of energy. “It will hydrate you, and it will prevent any blood sugar dip, especially in people who tend to be dehydrated, but I can’t see this being like Red Bull,” she explains. So manage your expectations.

In terms of how it may affect your taste buds, when we tried it, we found the consistency wasn’t as thick as we expected. It felt like sipping a slightly heavier version of water, leaving a little bit of an oily film in your mouth. The sweetness from the stevia, xylitol, and flavoring came through a lot, which most of our taste-testers didn’t like.

While some of us couldn’t get down more than a couple sips, others could see it being part of a three o’clock snack. And hey, maybe it doesn’t have to be as surprising delish as the original butter-laced coffee to fly off the shelves? Think about the popularity of (beauty-boosting) aloe water, after all—Jamie McKillop
