Also known as bulletproof coffee, the official recipe calls for unsalted grass-fed butter and two tablespoons of MCT (medium-chain triglycerides) oil.
Researchers from the College of Physicians and Surgeons, Columbia University and New York Obesity Research Center have found that MCT can help aid weight loss.
“Consumption of MCT oil as part of a weight-loss plan improves weight loss compared with olive oil and can thus be successfully included in a weight-loss diet. Small changes in the quality of fat intake can therefore be useful to enhance weight loss,” Dr Marie-Pierre St-Onge and Dr Aubrey Bosarge reported in The American Journal of Clinical Nutrition.
Moreover, grass-fed butter has high levels of omega-3s, which can help improve gut flora, cognitive function and energy levels.
Nutritionists are fans of the beverage, too.
According to New York nutritionist Amy Shapiro, RD, bulletproof coffee “can be a satisfying, energy-producing breakfast that provides many nutrients, satisfies hunger, and may cause your body to increase fat-burning, resulting in weight loss.”
But before you start adding lashes of butter to your morning brew, use caution.
According to Amy, bulletproof coffee “can add a lot of high-fat calories, if the rest of your day doesn’t consist of clean eating.”
In other words, if you’re already packing in high levels of sugar and carbs, your body may store the fat instead of converting it to energy.
