black magic
 

Drink coffee (black) before working out.

Caffeine causes the body to rely more on fat for fuel during a workout, rather than glucose,
But the caffeine effect is lessened when you eat a high-carbohydrate meal with it." Drink 1-2 cups of black coffee within two hours of working out, and emphasize healthy fats and protein if you're drinking it with a meal or snack.

Skip the cream and sugar (which add unwanted calories and fat), and avoid drinking coffee at other times of the day;(f#ck that) doing so can desensitize you to the fat-burning effects of caffeine.
