4 Metabolism Myths

4 Metabolism Myths

If you’ve ever read an article about weight loss, I’m sure you’ve seen the word ‘metabolism’ thrown in there a few times.

And like many health and nutrition topics, there’s a lot of misguided myths floating around, too.

Here are four of them you should have a more accurate picture about.

Metabolism will decline past age 30

While it’s true metabolism declines with age, it isn’t a drastic, fall-off-the-cliff like it’s made out to be.

If you gain weight as you enter your 30’s, it may be due to other controllable factors and not solely genetics. It’s the decade of sitting long hours in the office, taking care of kids, and having less time to work out, after all.

All exercise boosts metabolism


Aerobic exercise is always good, but isn’t enough to build muscle. And a lack of strength exercises in your workout can lead to metabolic decline thanks to poor muscle mass.

“Strength training builds muscle, which needs to be fed calories,” Lisa Nordquist, an ACE-certified personal trainer said. “That requires your body to turn on its engine — a.k.a. your metabolism — to maintain that muscle mass.”

Skinny people have faster metabolism rates

As alluded to in the previous point, metabolism is more about muscle mass than body size. Muscles use more energy than fat when you’re resting, meaning you’re burning gas even when you aren’t engaged in full-on physical activity.

So, it’s actually the more of the opposite – larger people burn more calories rather than skinnier ones.

“The more you weigh, the more oxygen your muscles need in order to support that weight and all of your body’s functions,” Jason Karp, Ph.D., author of Running for Women, said.

Eating food late at night leads to weight gain

Timing and frequency of meals actually doesn’t have a big impact on your resting metabolic rate. Quality and quantity is what really matters here. So, ensure your diet provides all the essential nutrients your body needs, while balancing caloric intake in a healthy range.
