Keto Diet: Hot Flashes Explained

The ketogenic diet, commonly known as keto, is a weight-loss plan that involves eating high-fat foods such as avocado, cheese, and bacon. While some people advocate for this diet as a way to help midlife women lose weight and improve their health during menopause, others urge caution. There is limited research on the long-term effects of the keto diet, and it may not be suitable for everyone. One concern is that the keto diet can cause keto flu, which includes symptoms similar to menopause, such as headaches, fatigue, and sleep problems. Additionally, the keto diet may impact heart health and bone density, especially during menopause when the risk of heart disease and osteoporosis increases. While some women report that keto helps reduce hot flashes and other menopausal symptoms, others find that it makes them worse.

Keto may reduce hot flashes by providing an alternative fuel source

The keto diet may help reduce hot flashes by providing an alternative fuel source for the body. The diet restricts carbohydrates, forcing the body to turn to fat as its primary fuel. This process is known as ketosis, where the body breaks down fat in the liver and uses ketones for fuel instead of glucose.

Ketosis can help regulate hormones, which may prevent or reduce the intensity of hot flashes. Additionally, a ketogenic diet can lower insulin levels and increase insulin sensitivity, which is beneficial during menopause as insulin sensitivity tends to decrease. One study found that a ketogenic diet improved insulin levels and sensitivity in women with endometrial or ovarian cancer.

The keto diet may also help with weight management during menopause. A low-carbohydrate diet has been linked to a lower risk of postmenopausal weight gain, and the keto diet's appetite-suppressing effects may further aid in weight loss.

However, it is important to note that there is limited research specifically on the impact of the keto diet on menopause symptoms. While it may help with some symptoms, such as weight gain, it is not a cure-all. The keto diet has also been associated with increased LDL cholesterol, which may be risky during menopause as the decline in estrogen already increases the risk of heart disease.

Furthermore, a keto diet can make it challenging to consume enough fiber and certain nutrients, so careful planning is necessary to ensure adequate nutrient intake. Overall, while the keto diet may help reduce hot flashes by providing an alternative fuel source, it should be approached with caution and under the guidance of a healthcare professional.

Keto can help manage weight gain during menopause

The keto diet is a very low-carbohydrate, high-fat diet that some people recommend to ease menopause symptoms and balance hormones. It is a weight-loss plan that has gained popularity in recent years.

During menopause, women often experience weight gain, food cravings, and insulin resistance. The keto diet has been shown to positively affect weight loss, lipid profiles, and glycemic control in people who are overweight or obese.

Impact on Weight Gain

There is no research on whether the keto diet is an effective way to maintain a healthy weight during menopause. However, a large 2017 study of nearly 89,000 females aged 49–81 years compared four diets to see how well they worked. The researchers found that people who followed a low-carbohydrate diet had a lower risk of postmenopausal weight gain than other diet types.

Effect on Food Cravings

During menopause, many women experience increased hunger and cravings. The keto diet has been shown to promote increased feelings of fullness and decrease appetite. This may be due to the fact that foods high in protein and fat have a positive effect on satiety through several different processes.

Effect on Insulin Sensitivity

Night sweats and hot flashes, two symptoms of menopause, have been strongly associated with insulin resistance in menopausal women. Some studies show that the keto diet may lead to improved insulin resistance, lower insulin levels, and a reduction in the number of medications people with diabetes use to reach their target blood sugar.

Potential Risks of the Keto Diet

Research on the long-term impact of the keto diet is still ongoing, but studies suggest there are some risks. The keto diet may increase the risk of developing kidney stones and may negatively impact heart health by increasing levels of low-density lipoprotein (LDL) or "bad" cholesterol.

Additionally, the severe restriction of carbohydrates in the keto diet may lead to nutrient deficiencies, as many carbohydrate-rich foods are also rich in vitamins, minerals, fiber, and phytochemicals.

Bottom Line

While the keto diet may help manage weight gain and improve other symptoms during menopause, it is not a one-size-fits-all approach and may have unpleasant side effects. It is important to consult with a healthcare provider and registered dietitian to determine the best eating plan for your individual needs.

Keto may help balance insulin levels

The ketogenic diet (KD) is a diet in which the amount of carbohydrates is limited to less than 50 g per day, while the intake of fat is increased to ensure an adequate energy intake. The KD is considered an interesting nutritional approach for weight loss and improvement in insulin resistance.

The KD has been shown to have a positive effect on insulin resistance in subjects with overweight or obesity. However, some studies have observed a significant improvement in insulin sensitivity in response to low-carbohydrate diets even in the absence of weight loss. The direct effects of the KD on insulin sensitivity are mediated by its ability to lower blood glucose and insulin levels, as well as its impact on fat tissue and oxidative stress.

The KD reduces intestinal absorption of monosaccharides, leading to decreased postprandial glycemia and lower insulin requirements from the pancreas. This results in lower insulin levels and an improved insulin-to-glucagon ratio. The restriction of carbohydrates in the KD decreases the intestinal absorption of mono-saccharides, which leads to lower blood glucose levels and reduces the fluctuation of blood glucose.

The KD also has a positive effect on fat tissue. It significantly reduces the amount of visceral adipose tissue depots, which are associated with an increased availability of bioactive lipids that induce subclinical inflammation and insulin resistance. Additionally, the KD reduces adipose tissue cell size, which is positively correlated with muscle triglyceride content and negatively correlated with insulin sensitivity.

Furthermore, the KD improves oxidative stress by increasing the body's resistance to it. Ketosis, induced by the KD, increases the production of reactive oxygen species (ROS), which can have both beneficial and harmful effects on insulin sensitivity. However, ketosis reduces oxidative stress, and ketone bodies may exert their protective effects directly or indirectly.

In summary, the KD may help balance insulin levels by lowering blood glucose and insulin, improving fat tissue distribution, and enhancing the body's resistance to oxidative stress.

Keto can improve sleep patterns

The ketogenic diet, or keto, is a weight-loss plan that involves eating high-fat foods and limiting carbohydrates. While some people experience sleep disturbances when they start the diet, known as "keto insomnia", others find that keto improves their sleep patterns.

When you follow the keto diet, your body enters a state called ketosis, where it uses fat instead of carbohydrates as its primary source of fuel. This process can impact your sleep in a few ways.

Firstly, the reduction in carbohydrates can lead to a decrease in the production of serotonin and melatonin, hormones that regulate sleep. This can make it difficult for some people to fall asleep or stay asleep, resulting in keto insomnia.

However, the increase in fat consumption on the keto diet may have a beneficial effect on sleep. A diet high in healthy fats has been linked to improved sleep. Additionally, the keto diet can help with weight loss, which can indirectly lead to better sleep. Obesity and sleep quality are closely linked, and losing weight can reduce the risk of sleep disorders such as obstructive sleep apnea.

Tips for Improving Sleep on Keto

If you're experiencing keto insomnia, there are a few strategies you can try to improve your sleep:

• Save your carbs for later in the day: Eating carbohydrates at dinner gives your body time to use them and produce the hormones needed for sleep.
• Incorporate sleep-inducing foods: Tart cherries, bananas, and oats contain significant amounts of melatonin, which can help you sleep. Bananas are also rich in L-tryptophan and magnesium, which can promote relaxation and better sleep.
• Stay hydrated: Dehydration can lead to sleep issues, and people on the keto diet need to pay close attention to their water intake as the body releases a lot of water when reducing carbohydrates.
• Exercise: Physical activity during the day can help you fall asleep faster at night and improve sleep quality.
• Relaxation techniques: Finding ways to relax and unwind before bed, such as reading or listening to music, can help prepare your body for sleep by lowering your heart rate and reducing tension.
• Practice good sleep hygiene: Establish a consistent sleep routine, make sure your bedroom is quiet and dark, avoid electronic devices before bed, and avoid large meals, caffeine, and alcohol close to bedtime.

Keto may reduce inflammation during menopause

The keto diet is a very low-carbohydrate, high-fat diet that some people recommend to ease menopause symptoms and balance hormones. However, it may not be suitable for all women due to potential side effects.

The keto diet puts the body into a state of ketosis, where it uses fat for energy instead of sugar (glucose). This metabolic state is achieved by drastically restricting carbohydrate intake and replacing it with fat. Typically, a keto diet consists of:

• 5-10% carbohydrates
• 20-30% protein
• 70-90% fat

Keto and Menopause

The keto diet may help with certain menopause symptoms, but its effectiveness varies. Here's how it may help:

• Weight Gain: Keto can help prevent weight gain during menopause. A large study of nearly 89,000 women found that those on a low-carb diet had a lower risk of postmenopausal weight gain compared to other diets.
• Appetite and Cravings: The keto diet may decrease hunger and appetite, which can be beneficial during menopause when many women experience increased cravings. A study found that following keto for eight weeks increased levels of glucagon-like peptide 1 (GLP-1), an appetite-regulating hormone, in female participants.
• Insulin Sensitivity: Menopause can decrease insulin sensitivity, leading to impaired insulin usage by the body. The keto diet may improve insulin sensitivity and promote better blood sugar control. A study on women with ovarian or endometrial cancer showed improved insulin sensitivity after 12 weeks on a keto diet.

Potential Risks and Side Effects

While keto may offer benefits during menopause, there are some potential risks and side effects to consider:

• Heart Disease Risk: Menopause increases the risk of heart disease, and keto may compound this risk by increasing LDL ("bad") cholesterol levels. Studies have shown that keto diets are associated with increased LDL cholesterol and endothelial dysfunction, which involves a narrowing of the blood vessels on the surface of the heart.
• Nutrient Deficiencies: Restricting carbohydrates can make it challenging to meet recommended intakes for certain nutrients. A keto diet may lead to deficiencies in calcium, folate, magnesium, manganese, potassium, thiamin, and vitamins D and E.
• Fiber Intake: Keto diets tend to be low in fiber, which is essential for gut health, weight management, immune function, and protection against cardiovascular disease and type 2 diabetes.
• Saturated Fat Intake: Keto diets often contain more saturated fat, which is associated with increased LDL cholesterol.
• Keto Flu: The keto diet can cause "keto flu," a set of symptoms that occur during the transition to ketosis. These symptoms, including fatigue, hair loss, sleep problems, and mood changes, may temporarily worsen menopause symptoms.

The keto diet may offer some benefits for women during menopause, such as improved insulin sensitivity, weight management, and reduced cravings. However, it may also increase certain risk factors for cardiovascular disease and cause nutrient deficiencies. Additionally, the keto flu may exacerbate menopause symptoms during the initial transition period.

It's important to note that keto may not be a universal solution for all women during menopause. Consulting with a healthcare professional before making dietary changes is essential to ensure it aligns with your specific needs and health goals.
