Keto and menopause might seem unrelated, but as the ketogenic diet gains popularity, many women are exploring its potential effects during this significant life transition. Menopause marks the end of a woman's menstrual cycles and reproductive years, accompanied by a decline in estrogen production. While some believe the keto diet can alleviate certain menopausal symptoms, it's crucial to understand the potential downsides and the connection to hot flashes.
What is the Keto Diet?
The keto diet is a restrictive eating plan that fundamentally alters the body's primary fuel source. It drastically reduces carbohydrate intake, forcing the body to switch from using glucose (derived from carbs) to using fat for energy. This metabolic shift induces a state called ketosis. A typical keto diet consists of high fat (55-60%), moderate protein (30-35%), and very low carbohydrate (5-10%) intake. Modified versions may include slightly more protein and carbohydrates but still significantly restrict carb consumption compared to a standard diet.
Potential Benefits of Keto for Menopause
Some individuals turn to the keto diet during menopause, hoping to address physical changes and alleviate symptoms.
Estrone Production
Theoretically, the high-fat content of the keto diet might offer short-term benefits. Fat is a precursor to estrone, a weaker form of estrogen produced by fat cells. An increase in fat consumption could potentially lead to a slight increase in estrogen levels.
Insulin Sensitivity
Menopause can decrease insulin sensitivity, potentially leading to elevated blood sugar levels. Research suggests that low-carb diets like keto may improve insulin sensitivity and help manage blood sugar. Improved insulin sensitivity may also reduce the risk of hot flashes, as insulin resistance has been linked to a higher incidence of these symptoms.

Weight Loss
Weight gain is a common symptom during menopause due to hormonal changes and a slower metabolism. The keto diet may assist with weight loss or weight maintenance after weight loss.
Reduced Cravings
Some women experience increased hunger and cravings during the menopausal transition. The keto diet may help reduce levels of ghrelin, a hormone that stimulates appetite, and increase the release of satiety hormones.
Keto and Hot Flashes: A Potential Paradox
While some hope the keto diet will ease hot flashes, it can sometimes have the opposite effect.
The Diuretic Effect
The keto diet's diuretic effect can worsen hot flashes and other menopause symptoms. Frequent urination, a common side effect of ketosis, leads to the loss of electrolytes like sodium, potassium, and calcium. This electrolyte imbalance can contribute to fatigue, aches, and pains, often referred to as the "keto flu," which can exacerbate menopausal symptoms.
Dehydration
The keto diet includes a very serious drop in the number of carbs that the body normally takes in. The low amount of carbs causes the body to have lower amounts of glycogen and insulin, and higher ketone levels. When the low-carb diet first begins, the body relies heavily on muscle glycogen for energy. However, for each bit of glycogen that the body uses, twice the amount of water is lost. This means that dehydration can occur easily once the body starts using up high amounts of glycogen. Being dehydrated can cause body temperatures to rise at night, causing night sweats.

The "Keto Flu"
As the body transitions into ketosis, individuals may experience the "keto flu," characterized by symptoms like nausea, insomnia, and fatigue. These symptoms can overlap with menopausal symptoms, potentially making them feel more intense.
Risks Associated with Keto During Menopause
Beyond the potential for worsened hot flashes, the keto diet poses several health risks, especially for menopausal women.
Heart Disease
Estrogen provides a protective effect against heart disease by positively influencing cholesterol levels and blood flow. This protection diminishes after menopause. The high saturated fat intake often associated with the keto diet may further increase the risk of heart disease by raising LDL ("bad") cholesterol levels.
Cancer
High consumption of saturated fat, particularly from red meat, is linked to an elevated risk of developing cancer.
Osteopenia and Osteoporosis
The decline in estrogen during menopause reduces bone mineral density, increasing the risk of osteoporosis. A keto diet can contribute to bone thinning due to decreased new bone growth and increased bone breakdown.

Nutrient Deficiencies
The restrictive nature of the keto diet can make it challenging to obtain adequate amounts of essential nutrients, including vitamins A, E, and K, calcium, magnesium, iron, and fiber.
Kidney Stones
The keto diet may increase a person’s of developing kidney stones.
Managing Keto Hot Flashes
Is it possible to avoid keto hot flashes? If you drink a lot of fluids and increase your carb intake, the keto flu does go away. But if you stay on the diet, it’s possible that it will get worse and it won’t go away.
Alternatives to Keto for Managing Menopause Symptoms
Given the potential risks, it's essential to explore safer and more sustainable approaches to managing menopause symptoms.
Exercise
Regular physical activity is a cornerstone of managing menopause symptoms and promoting overall health.
Hormone Replacement Therapy (HRT)
Hormone therapy can replace the hormones a person is losing, which can alleviate symptoms.
Lifestyle Modifications
Reducing alcohol and caffeine intake, prioritizing sleep, and exploring alternative therapies like acupuncture can provide relief.
Mediterranean Diet
The Mediterranean diet, rich in vegetables, fruits, healthy fats (olive oil, nuts, avocado), and lean protein, offers a balanced and sustainable approach to managing weight and supporting overall health during menopause.
Plant-Based Diets
Plant-based diets, emphasizing fruits, vegetables, whole grains, and legumes, have been associated with less bothersome menopausal symptoms.
