ARE YOU FASTING YOUR WAY TO A SLOWER METABOLISM?

Intermittent fasting has been sold as the holy grail of fat loss. Eat less, eat less often, lose more weight, simplify your life. Sounds perfect… until it doesn’t.

Because here’s what no one is talking about, especially when it comes to women in midlife. Fasting just might be the fastest way to a slower metabolism.

As with any diet, fasting “works”. Until it doesn't. Skipping meals, time restricted eating, depriving your body of fuel sends a signal that your body is under stress. And done on repeat, your body decides it doesn’t feel safe anymore.

In your 20s and even 30s, skipping meals here and there might not have had a noticeable impact. Your body was more resilient, more tolerant. Hormones were more forgiving. Stress was easier to buffer. But in your 40s and 50s, it's a different story. And to be clear, results are less about your age and more about how long you've been doing things that don't serve your body.

In midlife, your body is already navigating fluctuating estrogen, increased cortisol sensitivity, and a nervous system that’s less tolerant of stress. Intentionally adding something that creates internal inflammation and stress on top of everything else wil not give you the results you're looking for. And yes, fasting is a stressor.

When you go long periods without eating, your body doesn’t automatically think, “Oh great, we’re burning fat efficiently today.” It interprets not eating as a potential threat to survival. So it does what it was created to do, adapts. It slows things down to conserve energy and becomes more efficient at holding onto fat because fat is essential for our survival. There's a reason that the participants on survival reality shows are excited when they find a food source that has fat.

Your body also increases cortisol in an effort to keep blood sugar stable in the absence of food. And that’s where things start to backfire. Elevated cortisol isn’t just about stress alone, it directly impacts fat storage, especially around the midsection. So if you’re fasting, skipping breakfast, pushing your first meal to noon, and still not losing weight (or worse, gaining belly fat), now you know why.

Your body is prioritizing survival over fat loss in its best efforts to save you. Another piece most people miss is blood sugar instability. When you delay eating, especially after a poor night’s sleep or a stressful morning, your body is already playing catch-up. Cortisol is elevated and telling your body to store fat. Blood sugar is dyregulated, telling your body to not only store fat, but burn muscle to create glucose to feed the brain. Which is what happens when you're not eating enough. All you're doing is increasing your body's stress response by restricting fuel.

When you finally do eat, you are more likely to overeat and experience cravings for things you might not normally choose, aka sugary, carby foods. Like you just jumped on a rollercoaster. Spike (store fat),crash (burn muscle), cravings, repeat.

Over time, this pattern contributes to insulin resistance, which is one of the biggest drivers of stubborn weight gain in menopause, not to mention a contributor to metabolic disease. Weight loss can no longer be just about calories. It needs to be about how your body is responding hormonally to what you’re doing.

Now, does this mean fasting is “bad”? Not necessarily. But it’s not universally beneficial, especially not for women in midlife. The last thing a woman in menopause needs on top of dealing with fatigue, weight loss resistance, poor sleep, brain fog, high stress or any of the 103 documented symptoms, is to restrict her fuel. In fact, for most women, the better approach is the opposite: Eat earlier. Eat consistently. Stabilize blood sugar. Fun fact, when blood sugar is stabilized, hormones can balance. It's time to support your metabolism instead of stressing it.

Because when your body feels safe, it works with you. When it doesn’t, it works against you. And if you’re constantly telling your body that food is scarce, even if that’s intentional, it will adapt in ways that make fat loss harder, not easier. Here’s the truth the dieting industry doesn't want you to hear: More restriction is not the answer in menopause. Better regulation is. So if fasting “used to work” but doesn’t anymore, it’s not because you’re broken. It’s because your body has changed. And your strategy needs to change with it.
