Fat Burners, often referred to as thermogenics, are commonly used by those seeking to lose weight. These products work by increasing your core body temperature, resulting in an increase in you metabolic rate. The higher this rate, the more calories you will burn, enabling you to achieve a state of calorie deficit with greater ease. Fat burners will also assist in the breakdown of fatty acids, making them more available to use. This, in turn allows you to burn more body fat as your body's preferred source of fuel, resulting in fat loss and an improved body composition. Fat burners can be used first thing in the morning, prior to fasted cardio or as a substitute for a pre-workout, before your training sessions.
