Keto Diet: Hot Flashes Friend Or Foe?

The ketogenic diet is a restrictive eating style that changes the type of fuel the body uses. It involves drastically cutting down on carbohydrates and replacing them with fat. While it is a popular eating style, there is no evidence that it is beneficial for menopause. However, some people turn to keto to address physical changes and menopause symptoms such as hot flashes, night sweats, and difficulty sleeping. The high-fat diet may reduce some menopause symptoms as fat is a precursor for estrone, a weak type of estrogen. But the keto diet also has downsides and may worsen menopause symptoms.

Keto may reduce hot flashes by optimising hormones

The keto diet is a restrictive eating style that changes the type of fuel the body uses. By depriving the body of glucose, the main source of energy that comes from carbohydrates, the body is forced to turn to fat for fuel. This metabolic state is known as ketosis. While there is no evidence that the keto diet specifically helps with menopause symptoms, it may help reduce hot flashes by optimising hormones.

The keto diet can help optimise hormones by improving insulin sensitivity. Menopause can cause changes in hormone levels, including a decrease in insulin sensitivity, which can impair the body's ability to use insulin effectively. Research suggests that the keto diet may improve insulin sensitivity, thereby promoting better blood sugar control. This can be especially beneficial during menopause as insulin resistance has been linked to a higher risk of hot flashes.

Additionally, the keto diet can help regulate hunger-regulating hormones such as insulin, leptin, and ghrelin, which may be beneficial during menopause as many women experience increased hunger and cravings during this time.

Potential Side Effects

While the keto diet may offer benefits for women during menopause, it is important to consider potential side effects. The keto diet has been associated with an increased risk of heart disease, as it can lead to increased LDL ("bad") cholesterol. This is particularly concerning for menopausal women, as the decline in estrogen during menopause already increases the risk of heart disease.

The keto diet can also lead to micronutrient deficiencies, decreased fibre intake, and increased saturated fat intake, which may have negative health consequences. Additionally, the keto flu, a set of symptoms that occur as the body transitions into ketosis, can worsen certain symptoms of menopause, including fatigue, sleep problems, and mood changes.

The keto diet may help reduce hot flashes by optimising hormones, particularly insulin. However, it is important to note that the keto diet may also have negative effects on overall health, especially for menopausal women. Therefore, it is recommended to consult with a healthcare professional before making any dietary changes to ensure that it is safe and appropriate for your individual needs.

Keto may help with weight gain during menopause

Women over 40 often seek new ways to lose weight in response to age-related physical changes. The keto diet is a weight-loss plan that continues to gain popularity. Some people advocate for this eating plan for midlife women who want to lose weight and improve their health during the menopause transition.

The keto diet is a restrictive eating style that changes the type of fuel your body uses. The diet starves the body of glucose, the main source of energy that comes from carbohydrates. Without glucose, the liver transforms stored fat into chemicals called ketone bodies, which are then consumed by the brain and body as energy.

Weight gain is a common symptom of menopause, often attributed to alterations in hormone levels and a slower metabolism. Research suggests that the keto diet may help prevent weight gain associated with menopause. A 2017 study of nearly 89,000 women aged 49-81 years found that those who followed a low-carb diet had a lower risk of postmenopausal weight gain than those on other diets.

Additionally, some women experience an increase in appetite or food cravings during the transition into menopause. The keto diet may help decrease hunger and appetite, which could be beneficial during menopause. A 2019 study found that following the keto diet for 8 weeks increased levels of glucagon-like peptide 1 (GLP-1), a hormone that regulates appetite, in female participants.

Considerations

While the keto diet may offer benefits for women during menopause, it is not without potential side effects and risks. It may increase certain risk factors for cardiovascular disease and restrict the intake of several important nutrients. Additionally, the "keto flu," a set of symptoms that occur as the body transitions into ketosis, may temporarily worsen symptoms of menopause.

It is important to consult with a healthcare professional before making any significant dietary changes, as keto may not be a good fit for everyone.

Keto may cause more menopause symptoms

While some people advocate for the keto diet as a way to alleviate menopause symptoms, experts urge women to proceed with caution. The keto diet is a restrictive eating style that changes the type of fuel the body uses. The diet deprives the body of glucose, the main source of energy that comes from carbohydrates. Instead, the liver transforms stored fat into ketone bodies, which are then consumed as energy.

The keto diet may cause more menopause symptoms, especially in the short term. The "keto flu" is a set of symptoms that arise as the body enters ketosis, and these can include headaches, fatigue, sleep problems, and heart palpitations, which are also menopause symptoms. The keto flu can be minimized by staying hydrated and getting plenty of electrolytes, but it may get worse if you stay on the diet.

The keto diet may also increase the risk of certain health issues, including heart disease, cancer, and osteoporosis. Heart disease is a serious issue for midlife women, as they lose the heart protection that estrogen provides once they pass into menopause. The keto diet's high saturated fat content increases LDL cholesterol, which increases the risk of heart problems. The diet may also contribute to the early and later stages of bone thinning.

In addition, the keto diet may lead to nutritional deficiencies, as it can be challenging to consume enough of certain nutrients. For example, one study found that those on the keto diet consumed less fiber, and people may eat fewer fruits and vegetables to avoid carbohydrates, resulting in lower intakes of vitamins, minerals, and prebiotics.

While the keto diet may help with weight loss during menopause, it is not a one-size-fits-all solution, and there are other diets that may be more beneficial, such as the Mediterranean diet or plant-based diets. Experts recommend consulting with a doctor or dietitian before starting any new diet.

Keto may help with insulin sensitivity

The ketogenic diet has been shown to improve insulin sensitivity, which may be one of the reasons it is often recommended to women during menopause. Insulin is a hormone that regulates the transportation of sugar from the bloodstream into cells to be used as fuel.

Menopause can cause a decrease in insulin sensitivity, impairing the body's ability to use insulin effectively. The ketogenic diet may improve insulin sensitivity and promote better blood sugar control.

One study found that following a ketogenic diet for 12 weeks improved insulin levels and insulin sensitivity in women with endometrial or ovarian cancer. Another review reported that reducing carbohydrate consumption may decrease insulin levels and improve hormonal imbalances, which could be especially beneficial during menopause.

Additionally, studies suggest that insulin resistance may be linked to a higher risk of hot flashes, which are a common side effect of menopause. The ketogenic diet can also help prevent weight gain, which is a symptom of menopause, by decreasing carbohydrate intake.

However, it is important to note that the benefits of the ketogenic diet on insulin sensitivity and menopause are believed to be short-term only. Furthermore, there are some potential side effects and health risks associated with the ketogenic diet, including very low blood sugar, kidney problems, and nutrient deficiencies.

Therefore, while the ketogenic diet may help improve insulin sensitivity and reduce hot flashes in the short term, it is important to consult with a healthcare professional before making any significant dietary changes.

Keto may not be a long-term solution

While the keto diet may be a good short-term solution for menopausal women to lose weight and reduce hot flashes, it may not be a good long-term solution.

Firstly, the keto diet is a restrictive eating style that changes the type of fuel your body uses. The diet deprives the body of glucose, the main source of energy that comes from carbohydrates. This means cutting out foods such as legumes, bread, pasta, cereal, starchy vegetables, and sweets. This can be difficult to follow long-term and may not be a sustainable solution.

Secondly, the keto diet may worsen menopause symptoms and increase certain health risks. While the fat-rich keto diet may reduce some menopause symptoms, such as hot flashes, it can also cause more symptoms, especially in the initial stages. The "keto flu" can include symptoms such as fatigue, aches, and pains, and can worsen existing menopause symptoms.

Thirdly, the keto diet may increase the risk of heart disease, cancer, and osteoporosis. The high intake of saturated fat associated with the keto diet can increase LDL ("bad") cholesterol, which may be risky for menopausal women as the decline in estrogen increases the risk of heart disease.

Finally, the keto diet may lead to nutritional deficiencies and a lack of fibre. It can be challenging to consume enough of certain nutrients, such as calcium, vitamin D, vitamin C, and magnesium, on a keto diet. Additionally, the low intake of fruits and vegetables can result in a lack of fibre, which is important for gut health, weight management, and immune function.

In conclusion, while the keto diet may provide some short-term benefits for menopausal women, it may not be a sustainable long-term solution due to its restrictive nature, potential health risks, and nutritional deficiencies. It is always recommended to consult with a healthcare professional before making any significant dietary changes.
