The belief that cardio is the most efficient way to lose weight and stay fit was and still is popular in the fitness world. People who don’t exercise also believe that only hours spend on the treadmill can make them look better and they never dare try. But is this true and where does this stereotype spur from?
Myth #1 – You need to do at least an hour of cardio to burn fat.
Of course, many bodybuilders do cardio daily, sometimes for extended periods but remember they usually eat a lot and they prepare for competitions where single digit body fat percentages are a must. Even then, many of them only do cardio a few times a week for half an hour at a time.
You have to remember that weight and fat loss are a process that comprises of exercise and nutrition. So how much cardio you need to do will depend on your nutrition and other physical activity you perform daily. For example, if you have a sedentary job, yes, more cardio will be both healthy and optimal for weight loss. But if you spend most of the day on your feet, you may want to reduce cardio and focus on weight lifting or interval training.
Myth #2 – Fasted cardio burns fat better and faster
This is a popular one. We assume that in a fasted state our body has no choice but to turn to fat stores for energy. It turns out the opposite may be true – we will waste out muscle tissue away and end up ‘skinny fat’. A 2011 study concluded that fat burning is consistent regardless of whether or not you’ve eaten before a workout. Other research shows an increase in muscle catabolism from fasted cardio. Stick to basics – calories in vs. calories out. Perform cardio and mix it up to keep your body guessing and you are set for success. No need to be doing your cardio passing out from hunger. Eat a nice nutritious breakfast and it will enhance your muscle growth and cardio performance.
Myth #3 – You can’t lose weight without cardio
The one and only way to lose weight (and fat) is by creating a calorie deficit by diet or exercise and preferably both. The healthiest way to lose is to combine a balanced diet, cardio and resistance training. Lifting weights is important since it helps build muscle mass which increases your BMR (Basal Metabolic Rate). This means that the more muscle you have the more calories you will burn just ‘living’ and performing everyday tasks. You can create a calorie deficit by dieting and lifting but we certainly recommend adding cardio for improved effects and cardiovascular health!
To summarize, the best and healthiest approach to weight loss is balance. A healthy diet with a moderate amount of cardio, interval and resistance training will definitely show results and the variety will keep you on your toes, too!
