Cutting carbs feels logical. Carbs spike insulin, insulin stores fat, so fewer carbs means less fat, right?
Not exactly. And definitely not for women over 40.
Here’s what actually happens when you cut carbs too aggressively:
Your energy crashes. Carbohydrates are your body’s preferred fuel source. Cut them too low and your workouts suffer, your brain fog gets worse, and you’re exhausted by 2pm — which makes every healthy habit harder to maintain.
You lose muscle, not just fat. When carbs are too low and calories drop with them, your body starts breaking down muscle for fuel. In midlife, when you’re already fighting natural muscle loss from hormonal changes, this is the last thing you want. Less muscle means a slower metabolism. It’s the opposite of the goal.
Your cortisol goes up. Low carb diets can actually spike cortisol — your stress hormone. Elevated cortisol in midlife is already a problem for most women thanks to life stress and hormonal shifts. Adding diet stress on top of it makes belly fat worse, not better.
You can’t sustain it. You white-knuckle it for a few weeks, feel deprived, eventually eat all the carbs, feel like a failure, and start the cycle over. Sound familiar?
The goal was never to eat less. It was to eat smarter. The right carbs, in the right amounts, at the right times — paired with enough protein and progressive strength training — is what actually moves the needle after 40.
Carbs are not the enemy. An unsustainable approach is.
