We’ve all heard the saying “sugar is bad for you,” but what if I told you it goes beyond your waistline? If you’re in perimenopause or menopause, sugar doesn’t just lead to weight gain—it wreaks havoc on your hormones, too. Let’s break down how sugar affects your body, particularly during this pivotal time of life.

Insulin Resistance and Midlife Hormonal Shifts

Insulin is a hormone that regulates blood sugar by helping your cells absorb glucose. When we eat a lot of sugary or refined carbohydrates, our blood sugar levels spike, and our body releases insulin to bring things back to normal. Over time, though, this constant spiking of blood sugar can lead to a condition called insulin resistance.

Insulin resistance happens when your cells become less responsive to insulin, making it harder for your body to regulate blood sugar. You’re left with higher blood sugar levels and more insulin floating around, which often leads to weight gain, fatigue, and increased cravings for—you guessed it—more sugar.

During perimenopause and menopause, things get even more complicated. The natural decline in estrogen that happens during this time impacts how your body responds to insulin. Estrogen plays a significant role in keeping your cells sensitive to insulin. As it declines, your risk of insulin resistance increases, making blood sugar regulation harder. This means you’re more prone to experiencing irregular blood sugars, which sets off a vicious cycle of sugar cravings, overeating, and further hormonal imbalance.

Sugar’s Impact on Mood and Cravings

Estrogen and progesterone don’t just regulate your cycle—they also play a key role in your mood. These hormones interact with neurotransmitters like serotonin and endorphins, which help you feel good and regulate your emotions. As these hormone levels fluctuate or drop during perimenopause, many women experience mood swings, irritability, and fatigue.

When your estrogen and progesterone levels bottom out, so do your brain’s feel-good chemicals like serotonin. The result? You might find yourself reaching for sugary snacks to boost your mood. The quick surge of sugar in your system gives you a temporary high by increasing serotonin and endorphin levels, but the crash that follows leaves you craving even more sugar—and feeling even worse.

The stress and fatigue that often come with hormone imbalances only make the cravings for sugar stronger, leading to a pattern that’s hard to break.

The Endocrine Disruptor: Sugar

Sugar isn’t just spiking your blood sugar—it’s messing with your entire endocrine system. Endocrine disruptors are substances that interfere with the normal functioning of your hormones. While environmental toxins often get the spotlight, sugar is one of the most common and overlooked disruptors we consume daily.

Here’s how it works: when you consume too much sugar, it disrupts the production of insulin, throwing off your blood sugar regulation. When insulin gets out of balance, it can affect other hormones, like estrogen, testosterone, and cortisol (your stress hormone).

One of the key ways this happens is by reducing the production of SHBG (sex hormone-binding globulin), a protein that helps regulate estrogen and testosterone levels. When SHBG is low, both estrogen and testosterone can increase rapidly, causing hormone imbalances. This can lead to issues like irregular periods, acne, hair loss, and even more serious health problems like certain cancers.

The Progesterone Problem

On top of all that, when estrogen and testosterone levels are out of whack, they also overwhelm progesterone, the hormone that keeps you calm and relaxed. Low progesterone can lead to mood swings, anxiety, and insomnia—issues that many women in perimenopause are all too familiar with.

You can see how sugar creates a domino effect of hormonal chaos. It’s not just about weight gain anymore—it's about feeling off, out of balance, and constantly battling cravings and mood swings.

How to Break the Cycle & Stop Menopause Weight Gain

The good news is that you can take back control. Reducing sugar intake can dramatically improve not just your weight, but your hormone balance, mood, and energy levels. It’s important to start small: swap out refined carbs for whole grains, and try to add more fiber and protein to your meals to help regulate blood sugar. And remember, it’s not about perfection; it’s about progress.

Breaking the cycle of sugar cravings and hormonal disruption isn’t easy, but once you start making changes, you’ll notice improvements in how you feel—and that’s the most powerful motivation of all.
