If you love coffee and want to get more out of your workouts, you’ll want to pay attention. Nutritionist Liu Yili says drinking a small cup of unsweetened black coffee about an hour before exercise can help your body burn fat faster. Here’s why: caffeine raises your blood fatty acid levels, releasing fat into your bloodstream. Pair that with consistent, simple exercise, and you’ve got a recipe for faster fat loss.
How to Do It Right:
☕ Drink 1 Hour Before Exercise
Caffeine stimulates your metabolism and helps burn fat while keeping your central nervous system alert. Your heart rate and blood circulation speed up, making workouts more focused and longer-lasting. Timing is key—drink after breakfast, roughly an hour before you move.
⚖️ Keep It Moderate
Too much caffeine can backfire—think jitters, trouble sleeping, rapid heartbeat, high blood pressure, dizziness, and even dependence. Liu recommends staying under 300 mg of caffeine per day.
🌱 Choose Light-Roast Coffee
Caffeine and chlorogenic acid degrade at high temperatures, so lighter roasts preserve these fat-burning compounds better.
🚫 Stick to Pure Black Coffee
Black coffee packs more caffeine and zero sugar. If the bitterness is too strong, add a splash of milk or soy milk—but never sugar, which blocks fat metabolism.
💧 Stay Hydrated
Coffee is a diuretic, so don’t forget to drink water during your workout. Otherwise, you risk dehydration while trying to burn fat.
The takeaway? A simple pre-workout cup of black coffee, done right, can give your fat-burning efforts a serious boost. Pair it with exercise, and watch your results soar!
