When is the best time to burn fat?
Research suggests doing cardio in the morning on an empty stomach if you’re looking to shed some weight.
Since your body has not eaten since dinner, the carbohydrates in your muscles and liver will be depleted so your body has to dig into your fat stores for energy.
It is also suggested that lean people should eat easily digested carbs before morning workouts, such as oatmeal and fruit—or risk losing lean muscle mass.
