The latest trend has runners blending butter and oil (such as coconut) into their cuppa Joe, a drink often called “bulletproof coffee”—so-named after The Bulletproof Diet by Dave Asprey (and published by RW’s parent company, Rodale). Fans claim it provides lasting energy, staves off hunger, and helps burn fat efficiently.
Some of those claims make sense, says Liz Applegate, Ph.D., director of sports nutrition at the University of California Davis and RW’s nutrition columnist: “This drink can contain more than 400 calories and at least 200 milligrams of caffeine—it’s no surprise you feel good after drinking it.” As for weight-loss or metabolic benefits, she’s less convinced.
“There’s no evidence that drinking this instead of eating breakfast will change the way your body processes energy.” But if you like it and have room for the calories, Applegate says, there’s nothing wrong with starting your day with a cup.
RUNNERS WHO DRINK IT
2008 and 2012 U.S. Olympic Marathoner
“It’s a supercreamy, frothy, delicious coffee that will blow your mind and give you hours of long-lasting energy. The fat helps keep my hormones at the right levels. I’ve had fun adding cocoa or pumpkin-pie spice.”
2014 winner of the 147-mile Viking Way Ultra
“It’s my breakfast of choice on race morning. I add a sprinkle of cinnamon and Himalayan salt. As part of a high-fat, lower-carb diet, it helps me run for many hours.”
Ran across the U.S. in 2014 for veterans
“When I ran across America, I switched from a solid breakfast to bulletproof coffee on most days because it took less energy to digest and didn’t weigh me down.”
