Have You Tried FATwater?


First there was adding fat to coffee in the form of butter and MCT oil. Next, adding fat to water? Dave Asprey has created quite the empire behind his well known bulletproof coffee and riding on the tail of that, he’s recently created FATwater. But is this drink all it’s cracked up to be? Can it really help your feel more energized and lose weight? 

Breaking down FATwater: Does it really work?

FATwater is the latest offering in sports drinks. At first glance, it looks like a regular Gatorade alternative: bright colors, fruity flavors, sweetened with sugar-free xylitol. But the secret ingredient in this drink is emulsified fat.

Invented by drinkable fat trendsetter Dave Asprey, who previously created bulletproof coffee(which calls for adding two to four tablespoons of butter and coconut oil to your morning joe), FATwater has two grams (about 20 calories worth) of Asprey’s proprietary coconut oil, Bulletproof XCT oil. According to Asprey, this recipe combines the health benefits of medium-chain fatty acids with all the power of good old H2O for a drink that will supposedly give you energy, help you lose weight, and generally make you feel better.

But is all the hype legit? Can fat water really make you thin (and keep you hydrated)?

Probably not, says Regina Druz, M.D., an integrative cardiologist who specializes in diet and how fats are metabolized.

“One of the main benefits of saturated fats is that they’re filling, so I don’t see any advantage to adding them to water as that won’t increase the satiety effect,” she says. The issue she takes with Asprey’s formulation is that fats need food to be properly absorbed, debunking his spiel on improved intake.

The other problem, she explains, is that fat and water are digested differently. “Water is absorbed in the intestines, by a process called osmosis. This is passive and doesn’t require any energy,” says Druz. “But fat requires a special transport system that requires energy to digest it—not only is it not giving you a boost of energy, but it requires energy to burn it off, so the energy claim doesn’t really make sense, biologically speaking.”
