6 common fitness myths debunked

Posted: Updated:

CoreCamper.com's Ali Holman busts 6 common fitness myths.

1. MYTH: If you quit working out, your muscle will turn to fat

TRUTH: Muscle and fat are two different types of tissue. When you stop training, you lose muscle mass, which in turn slows your metabolism, he says. The slower metabolism in turn can cause weight gain when you stop working out — but one type of tissue doesn’t “turn into” the other.

2. MYTH: Carbs are bad

TRUTH: If you want to gain muscle, you're going to need carbs. If you take them out completely, you'll burn more body fat during training perhaps, but you can't keep it up for long. Carbs are fuel for intense workouts, fats are not. Choose a macro plan that suits your athletic goals. If you're an athlete, you're going to need more than protein to make it through a game.

You also need a minimum amount of carbs to ensure that your brain functions properly. The brain needs glucose to work. Your body can be ketonic and use fatty acids to fuel your muscles, but your brain can't.

3. MYTH: The more I sweat, the more calories I am burning

TRUTH: Sweating is not always related to heart rate — which is the best measure of exercise capacity. Sweat is just the body’s way to regulate body temperature, he says. And some of us just run hotter than others — sometimes independently of heart-rate levels

4. MYTH: Natural or organic foods are best for weight loss

TRUTH: No matter how "organic" your bread is, it still has calories. Yes, these foods may be healthier because they're more likely to be free of pesticides and other chemicals, but over eating "natural" food is still over eating.

5. MYTH: Carbonated drinks take calcium out of your bones

TRUTH: This myth got its start because soft drinks contain phosphorus. High levels of phosphorus/phosphate have been linked to reduced bone mass and higher fracture risk.

The effect is probably due to people replacing dairy with soda, not the phosphorus itself.

6. MYTH: Higher number on the scale means you are getting fatter

TRUTH: It depends where those pounds are coming from: fat or muscle. “The difference is the density! A pound of muscle takes up less space than a pound of fat. That’s why it’s possible to become leaner and healthier while at the same time gaining weight.
