Fat Loss Myths Part 2: Cardio Is Necessary For Fat Loss

Myth: It is necessary to perform cardio on a regular basis to lose fat.

Truth: Cardio is not necessary for fat loss, and contributes relatively little to a fat loss program compared to high intensity strength training.

To lose fat it is necessary to create a calorie deficit - you must consume fewer calories than you expend so the body obtains the difference from your fat stores. While overall activity level has an effect on daily calorie expenditure, additional “cardio” (steady state or interval training) burns relatively few calories even if performed for an hour or more at moderate intensity daily. A greater calorie deficit can be achieved by simply restricting calorie intake, with little time investment other than the few minutes required for planning and recording meals.

The most important benefit of exercise to a fat loss program is not the calories expended during workouts, but the maintenance of muscle tissue while fat is lost. This requires strength training. There is a direct relationship between lean body mass, particularly muscle mass, and metabolic rate - more muscle equals a higher metabolic rate. If calorie intake is reduced significantly without regular, consistent strength training, muscle tends to be lost along with fat resulting in a reduced metabolic rate. Cardio does nothing to prevent muscle loss and may even accelerate it. › Continue reading
