Calories and Menopause
5 Consequences of Eating Too Little
Calories are one of the first things most people cut when they’re trying to lose weight—especially during menopause. Worse, nothing seems to be working the way it used to, leaving you frustrated.
You’re not imagining it. The weight won’t budge, your energy crashes by 3 PM, and your body feels different. So, you double down: smaller portions skipped meals, and fewer calories. It feels like the only thing left to control.
But here’s the hard truth—cutting calories too far can backfire in ways that leave you feeling stuck, frustrated, and even worse than before.
If that sounds familiar, you’re not alone. Let’s examine what happens when your body doesn’t receive the necessary fuel—especially during this pivotal yet challenging transition.
Your Metabolism Slows Down
Calories are your body’s fuel, plain and simple. When you don’t eat enough, your metabolism adapts by slowing everything down.
This begins with your Basal Metabolic Rate (BMR), which is the number of calories your body burns to keep you alive. If your BMR drops, it gets harder to lose weight, even if you’re eating next to nothing. It’s like your body is hitting the brakes—and no one wins that race.
Calories Count for Nutrient Intake
Cutting them too far means missing out on the good stuff your body needs now more than ever: calcium, magnesium, healthy fats, B vitamins, and protein.
These support your hormones, bones, brain, and heart. Without them, your symptoms can feel worse, and recovery from stress or illness takes longer. Less isn’t always better.
Calories and Hormones Go Hand in Hand
Calories impact your hormones in real-time. When you undereat, ghrelin (your hunger hormone) increases and leptin (your fullness hormone) decreases.
Your brain thinks you’re in survival mode—and honestly, it’s right. Hunger becomes a constant fight, cravings spike, and sticking to any plan becomes a battle you’re not meant to win. You’re not broken—your hormones are responding to the lack of fuel.
More Stress, More Fat
Calories also influence your stress response. When your body feels deprived, it pumps out more cortisol, your stress hormone. High cortisol levels are associated with increased fat storage, particularly around the abdomen.
So, while you think eating less will help shrink your waistline, it may actually have the opposite effect. And if you’re feeling wired at night, overwhelmed during the day, or stuck in a cycle of weight gain, cortisol could be at the core.
Calories Support Muscle
Calories are essential for maintaining muscle mass, and muscle is your secret weapon.
It keeps your metabolism revving, your body strong, and your bones supported. However, if you cut too far, your body will turn to muscle for energy.
This results in reduced strength, tone and a slower metabolism over time. Not what we want—especially now.
Eat to Thrive, Not Just Survive
Calories aren’t the enemy. They’re the fuel your body needs to function, to heal, to balance hormones, and to help you feel like yourself again.
During menopause, your body is already working overtime to adjust to the changes happening inside. Don’t make it fight another battle by starving it of what it needs.
Weight loss that sticks around isn’t built on deprivation—it’s built on nourishment, consistency, and respect for your body’s needs. You don’t have to prove anything by eating less. You deserve to feel strong, clear-headed, and energized—and that starts by giving your body what it needs to work effectively.
