Harry also revealed a little trick to staying slim, telling the Sunday Times Styles magazine (via Yahoo Celebrity UK): "Bullet coffee. It's black coffee with a spoonful of butter in it and a spoonful of coconut oil, all mixed up together. I've been on it for two days. You don't get hungry. I wear 26 inch waist women's jeans. Boom."
So not only is he passing on a little wisdom about this coffee concoction that's working for him, but he also dropped this truth nugget: he wears a 26 inch waist women's jeans.
We always knew he had a lean frame, but never guessed his waist was that tiny.
As for the drink, we've totally had bulletproof coffee and it's really satisfying and delicious, you wouldn't believe it. Just a tip though: make sure to use a blender rather than stir in the butter and oil so it's well incorporated and frothed up. Then sprinkle with cinnamon. Yummy!
