Tired of running for miles without seeing the scale budge? You're not alone. Autumn Bates, a certified clinical nutritionist with a master's in nutrition and human performance, sees this frustration in many of her 600,000 YouTube subscribers and personal clients. Her controversial take on cardio exercise might change your entire approach to fat loss. Read on to discover why your daily runs could be sabotaging your weight loss goals and how a simple switch might be the game-changer you need.
It's Not About Calories Burned
The traditional energy-in, energy-out theory of weight loss has been "thoroughly debunked multiple times," according to Autumn. While running does burn more calories than walking, that's not the whole story. "A lot of weight loss comes down to hormone balance because your body ultimately can dictate how much energy it's burning outside of just exercise based on what you're eating and what your hormone profile is," she explains in her post. This hormone factor is why walking can actually be more effective than running for fat loss.
How Running Triggers Stress Hormones
When you run, your body demands quick energy, especially during the first two minutes of exercise. "Your body actually needs a lot more sugar in order to sustain this type of movement," Autumn points out. To provide this energy, your body releases cortisol, the stress hormone. "Cortisol's main job is to release sugar into the blood supply," she states. While helpful for the immediate exercise, consistently elevated cortisol from frequent running creates a problematic hormone environment for weight loss.
Why Runners Still Have Belly Fat
Ever wonder why dedicated runners sometimes still struggle with stubborn belly fat? Autumn explains: "Higher levels of cortisol causes your body to store weight specifically right here, right in the belly." This explains the frustrating paradox many runners experience - logging miles but not losing that midsection fat. "If you're noticing that you're gaining weight around your belly, when mathematically it shouldn't make sense because you're running so much... this is a sign that you probably are overdoing it," she warns.
Walking Naturally Balances Hormones
Unlike running, walking – especially outdoors – actually helps lower cortisol levels. "There's a study that has found that just walking outside for 15 minutes results in a decrease in your cortisol levels," Autumn notes. Walking has also been shown to lower BMI and reduce waist circumference. The fat-burning advantage comes from creating a more balanced hormone environment, rather than from the calorie burn itself.
A Marathon Runner's Surprising Discovery
As someone who completed the LA Marathon and multiple triathlons, Autumn speaks from personal experience. "I loved me some cardio. But from the increased cortisol levels, I did notice that I was getting some fat storage around my belly," she shares. After taking six months off from running to balance her hormones, she not only experienced reduced anxiety but also became leaner – a benefit she wasn't initially seeking but welcomed.
Finding Your Exercise Balance
Autumn isn't saying running is inherently bad. "Is running bad? No. Is running more often going to make you lose weight? Maybe, depends on where you're at right now," she clarifies. The key is understanding your body's signals and finding the right balance. For many people struggling with weight loss plateaus, reducing running frequency while increasing walking can lead to better results and improved hormone balance.
How To Make The Switch
Start by aiming for 10,000-15,000 steps daily. "The more you walk, the better. Walking is something that you really can't overdo, as long as you're not power walking," Autumn recommends. You can begin by "swapping out some of your running days for just walking days" or "including a 20-minute warm-up walk before your strength training." This approach helps loosen muscles while creating a more favorable hormone environment for fat loss - potentially the missing piece in your weight loss puzzle.
