If you’ve ever wondered what sugar does to your body during menopause, here’s what most women aren’t told: hormone shifts make your body more reactive to sugar. This then leads to weight gain, hot flashes, mood swings, energy dips, and belly fat.
You probably know sugar isn’t a healthy food… but what you might not realize is how little it takes to throw things off.
👉 Just 100 calories a day of sugar (which is about 25 grams of added sugars, or 6 teaspoons) is linked to 45 DIFFERENT negative health outcomes.
That’s about the amount in:
- 1 can of soda
- 1 small glazed doughnut
- 1 cup of sweetened yogurt
- 2 tablespoons of honey or maple syrup
- Even 2 small cookies
You don’t need all of those at once. Just one of them hits the threshold.
So What’s the Problem With Sugar in Menopause?
During menopause, your hormones, especially estrogen, progesterone, and cortisol are already fluctuating. Sugar adds fuel to that hormonal fire.
Here’s how:
1. Blood Sugar Spikes & Crashes
Estrogen helps regulate blood sugar. When it drops, your body becomes more insulin resistant, meaning sugar stays in your bloodstream longer and gets stored as fat more easily (especially around the belly).
2. Mood Swings, Anxiety & Brain Fog
Sugar triggers dopamine and serotonin (your feel-good neurotransmitters), but after that high comes a crash – leading to irritability, mood swings, and cravings.
3. Sleep Disruption
Sugar can raise cortisol, your stress hormone. That makes it harder to fall asleep and stay asleep, a big problem for women already dealing with menopause-related sleep issues.
4. Weight Gain & Belly Fat
High sugar intake is linked to insulin resistance, which makes fat storage (particularly in the abdominal area) more likely. This is especially true post-40.

Here are some of the negative health outcomes linked with a high sugar intake:
- Heart disease
- Diabetes
- Obesity
- Asthma
- Depression
- Some types of cancer (including breast, prostate, & pancreatic)
- Gout
- High blood pressure
- Stroke
- Obesity
- Liver disease
- High cholesterol
- Tooth decay
- Death
In a study published in the BMJ in 2023, researchers recommended eating less than 25 grams of sugar a day AND keeping sugary beverage intake to less than 1 a week (about 200-355 ml or ⅔ – 1½ cups).
So What Can You Do?
You don’t have to go cold turkey or eliminate every sweet forever, that’s not sustainable or joyful. Instead:
- Track your added sugar intake and be aware of sneaky resources like dressings, sauces, and “healthy” snacks.
- Choose low-glycemic foods to keep your blood sugar stable and support energy, mood, and metabolism.
- Reserve sweet treats for special moments not your daily routine.
- Read labels carefully. Look for “added sugars” and aim for single-digit grams per serving.
