“Black coffee gives you an artificial source of energy, and due to the adrenal stimulation, it helps you work better. Therefore, black coffee is often used as a pre-workout drink. It is also used in the keto diet during intermittent fasting, where you are reducing the amount of macronutrients in your body and how long it lasts. During the time when you don’t eat and don’t want your body to be gassy, that’s when you can drink black coffee before a workout to have an abundant source of energy. You can get a good workout without sacrificing the effectiveness of your training. This leads to more calories burned and weight loss,” says Brian Dsouza, sports nutritionist, celebrity fitness trainer.
