Perimenopause and sugar: why cravings and energy crashes can worsen, and how to cut back without feeling deprived

For many women, perimenopause brings hormonal ups and downs that affect more than mood. Energy, sleep, appetite and focus can all shift. In that setting, sugar can feel harmless in coffee or chocolate, yet it may amplify “spike and crash” patterns in blood glucose, leaving some women more tired, irritable and craving sweets again.

Perimenopause is marked by fluctuating estrogen levels rather than a smooth decline. Medical sources note that lower estrogen is linked with a higher tendency toward insulin resistance, which can make post-meal blood sugar rises more pronounced and the subsequent drop more noticeable in energy, appetite and concentration.

Because many perimenopause symptoms overlap with blood sugar instability, it can be hard to tell what is hormonal and what is dietary. In practice, the two can interact: poor sleep and stress can worsen cravings, while frequent high-sugar choices can make swings in energy and mood feel sharper.

Research also suggests that frequent vasomotor symptoms, such as hot flashes and night sweats, are associated with a higher long-term risk of type 2 diabetes in observational studies. The relationship is complex and does not mean symptoms alone “cause” diabetes, but it highlights the value of focusing on metabolic health during this transition.

Health guidance consistently recommends keeping added sugar low. The American Heart Association advises women to limit added sugar to about 25 grams per day, roughly 6 teaspoons. The World Health Organization recommends reducing free sugars to less than 10% of total daily energy, and suggests that going below 5% may provide additional benefits. The U.S. Dietary Guidelines for Americans 2020-2025 also advise keeping added sugars under 10% of daily calories.

Cutting sugar does not have to mean cutting joy. The most effective approach is reducing the “spike and crash” effect: build breakfasts around protein and fiber, reduce sugary drinks first, and lower sugar in coffee gradually while using flavor helpers like cinnamon or vanilla. Reading labels also matters because added sugars often hide in sauces, flavored yogurts and packaged “healthy” snacks.

As for non-sugar sweeteners, some people use them as a temporary bridge. WHO recommends against relying on them for weight control or lowering chronic disease risk, since long-term benefits are uncertain and some observational research links higher intake with health risks. If used, experts often suggest moderation and a short-term transition plan toward less sweetness overall.
