Keto For Women: Understanding Daily Carb Limits

The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. To stay in ketosis, a person should consume up to 50 grams of carbohydrates per day. However, there is no clear evidence-based consensus on the recommended carbohydrate intake for men and women. Ultimately, the recommendation for both genders is the same: fewer than 50 grams of carbs a day.

How many carbs can a woman eat on keto per day?

The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. The diet has gained traction as a potential weight-loss strategy due to its low-carb nature.

The keto diet typically restricts total carbohydrate intake to less than 50 grams a day, with some sources suggesting a limit as low as 20 grams a day. This is in contrast to the typical American diet, which consumes 225–325 grams of carbs daily.

To enter and remain in ketosis, the desired metabolic state for the keto diet, an intake of fewer than 50 grams of carbohydrates per day is recommended. This is a significant difference from other low-carb diets, which typically restrict carb intake to less than 130 grams per day.

There is no clear evidence-based consensus on the recommended carbohydrate intake for women specifically. However, recommendations for keto diets are usually the same for both men and women: fewer than 50 grams of carbs per day.

It is important to note that the keto diet may be risky during pregnancy, postpartum, or while nursing. In rare cases, it could lead to life-threatening complications like ketoacidosis, caused by excess ketones in the bloodstream and an inability to produce insulin.

Overall, the keto diet drastically restricts many foods, so it is important to regularly assess your nutritional intake and ensure you are meeting your micronutrient needs.

What foods can women eat on keto?

The keto diet is a low-carb, high-fat eating plan that has been used to treat specific medical conditions. It involves limiting total carbohydrate intake to 20-50 grams per day and getting 70-80% of daily calories from fat.

Animal Proteins

• Fish and shellfish: Salmon and other fish are carb-free and rich in B vitamins, potassium, and selenium.
• Meat and poultry: Fresh meat and poultry contain no carbs and are rich in B vitamins and minerals.
• Eggs: Each large egg contains less than 1 gram of carbs and about 6 grams of protein.

Dairy and Dairy Alternatives

• Cheese: Most types of cheese are very low in carbs and high in fat, making them great for the keto diet.
• Plain Greek yogurt and cottage cheese: These are high-protein foods that can be eaten in moderation on keto.
• Cream and half-and-half: These dairy products are very low in carbs and high in fat, making them ideal for keto.
• Unsweetened plant-based milk: Soy, almond, and coconut milk are keto-friendly, but avoid oat milk as it is too high in carbs.

Vegetables

• Green leafy vegetables: Spinach, kale, and collard greens are packed with vitamin K and iron.
• Peppers: Small hot peppers like jalapeños are ideal for keto-friendly appetizers, while larger, mild peppers like bell peppers can be used in many dishes.
• Summer squashes: Yellow squash and zucchini are versatile and low in carbs.
• High-fat veggies: Avocados and olives are unique among vegetables as they are fairly high in fat and low in net carbs.
• Other non-starchy vegetables: Cauliflower, spaghetti squash, jicama, and turnips are low in calories and carbs but full of nutrients and antioxidants.

Other Plant-Based Foods

• Nuts and seeds: These are healthy, high in fat, and low in carbs.
• Berries: Raspberries and strawberries are low in carbs and high in fiber, while blackberries and blueberries may not fit into strict keto diets.
• Shirataki noodles: These contain less than 1 gram of net carbs and only 15 calories per serving.
• Dark chocolate and cocoa powder: Choose dark chocolate with a minimum of 70% cocoa solids and eat it in moderation.

Fats and Oils

• Olive oil: High in oleic acid, a monounsaturated fat that has been found to decrease heart disease risk factors.
• Butter and ghee: These fats are good to include in the keto diet, and they don't appear to harm health as previously thought.
• Avocado and coconut oils: Good choices for cooking and baking.

Drinks

• Unsweetened coffee and tea: These are healthy, carb-free drinks that may help reduce the risk of diabetes.
• Unsweetened sparkling water: A keto-friendly alternative to soda that is generally free of sugar or sweeteners.

What are the benefits of keto for women?

The keto diet has become increasingly popular for weight loss and other health benefits. The diet is low-carb, high-fat, and moderate-protein, and has been used for centuries to treat specific medical conditions. While there is no clear consensus on the recommended carbohydrate intake for women, the keto diet typically recommends that women consume fewer than 50 grams of carbohydrates per day. Here are some benefits of the keto diet for women:

• Weight Loss: The keto diet can lead to weight loss by reducing appetite and decreasing insulin levels, which is a hormone that stores fat. A study found that participants who followed a keto diet for nine weeks lost weight and body fat, with male participants experiencing more significant results.
• Improved Blood Sugar Regulation: The keto diet can help regulate blood sugar levels, which is beneficial for people with diabetes and other metabolic disorders. Lowering carb intake can lead to a decrease in blood sugar spikes and improve insulin sensitivity.
• Reduced Insulin Sensitivity: In addition to regulating blood sugar, the keto diet may also reduce insulin sensitivity. This means that the body will need less insulin to process the same amount of glucose, which can be beneficial for people with diabetes or at risk of developing it.
• Improved Health Parameters: Following a keto diet has been associated with improvements in health parameters such as insulin resistance, high blood pressure, and elevated cholesterol and triglyceride levels. These benefits can lead to a reduced risk of cardiovascular disease and other health issues.
• Appetite Suppression: The high-fat content of the keto diet can have a satiating effect, reducing food cravings and decreasing appetite. This can make it easier for individuals to stick to the diet and achieve their weight loss goals.
• Potential Treatment for Medical Conditions: The keto diet has been used to treat specific medical conditions such as epilepsy, cancer, polycystic ovary syndrome, and Alzheimer's disease. It is also being explored as a potential supplementary treatment for certain cancers.
• Increased Energy: By using fat as the primary source of energy instead of glucose, the keto diet can provide a more stable and sustained energy source. This can lead to increased energy levels and improved physical and mental performance.
• Improved Mental Clarity: Some individuals report improved mental clarity and focus while on the keto diet. The stable energy source from fats and the reduction of blood sugar spikes can contribute to enhanced cognitive function.

It is important to note that the keto diet may not be suitable for everyone, and it is always recommended to consult with a healthcare professional before starting any new diet, especially during pregnancy or while breastfeeding. Additionally, the keto diet can be challenging to maintain due to its restrictive nature, and it may lead to initial side effects such as "keto flu." To ensure adequate nutrient intake, it is crucial to work with a registered dietitian when following the keto diet.

What are the risks of keto for women?

The keto diet is a high-fat, low-carb eating plan that has been used to treat specific medical conditions. While it has been used for weight loss, it is best to make this only a short-term dietary change.

There are several risks associated with the keto diet for women, and it is not suitable for everyone. Here are some of the potential risks:

• Cholesterol and heart health: The keto diet is associated with an increase in "bad" LDL cholesterol, which is linked to heart disease. Some research suggests that the diet could increase total and LDL cholesterol, while other studies indicate it may help increase "good" HDL cholesterol. If you have a history of high cholesterol or heart disease, keto may not be a good choice.
• Liver problems: The keto diet could overload the liver, as it has to metabolize a large amount of fat. This could worsen any existing liver conditions.
• Kidney problems: The kidneys help metabolize protein, and the high protein content of the keto diet may overload them.
• Constipation: The keto diet is low in fibrous foods like grains and legumes, which can lead to constipation.
• Fuzzy thinking and mood swings: Low-carb diets may cause confusion and irritability, as the brain functions best when its energy source is glucose from healthy carbohydrates.
• Nutrient deficiency: Restricting carbohydrates and certain food groups can lead to deficiencies in micronutrients such as selenium, magnesium, phosphorus, and vitamins B and C.
• Disordered eating: Any diet that severely restricts a group of foods could increase the risk of disordered eating patterns, such as binging or developing a fear of food or weight gain.
• Hormonal imbalance: The keto diet can impact stress and sex hormones, which can affect a woman's menstrual cycle and fertility. Excessive weight loss or nutrient depletion can signal to the body to shut down reproductive functions like ovulation. Additionally, cutting out fiber can lead to increased estrogen levels, worsening estrogen dominance.
• Thyroid issues: Going too low-carb can lead to issues with thyroid hormones, as glucose is needed to produce them. This could potentially cause hypothyroidism, leading to weight gain.

It is important to note that the keto diet is not suitable for women who are pregnant or nursing or who have certain underlying conditions, such as liver or kidney failure, alcohol or substance use disorders, disorders affecting fat metabolism, or certain nutritional deficiencies.

Before starting the keto diet or any significant dietary changes, it is crucial to consult a doctor and a registered dietitian to ensure it is safe and appropriate for your individual needs and health status.

How does keto affect women's hormones?

The keto diet can be a double-edged sword for women, offering benefits such as weight loss and improved metabolic health, but also potentially causing hormonal imbalances. Ultimately, the impact of keto on an individual woman's hormones will depend on her unique circumstances, and it may be beneficial to consult a doctor or dietitian before starting the diet.

Adrenals and the HPA axis

Long-term stress can cause an overproduction of the hormones cortisol and norepinephrine, leading to an imbalance that increases pressure on the hypothalamus, pituitary, and adrenal glands, which regulate hormones. This ongoing pressure may eventually lead to HPA axis dysfunction, which has been linked to various health issues, including sleep problems, a weakened immune system, and an increased risk of long-term health problems such as cardiovascular disease, stomach ulcers, and mental health conditions.

Studies suggest that very low-calorie diets can act as a stressor, increasing cortisol production. A 2007 study found that a low-carb diet increased cortisol levels compared to a moderate-fat, moderate-carb diet, although this study was conducted on obese men. More research is needed to understand the connection between diet and cortisol levels fully.

Menstrual cycle and fertility

A very restrictive diet may lead to irregular menstrual cycles or amenorrhea, which is defined as the absence of a menstrual cycle for three months or more. Amenorrhea occurs due to a drop in levels of various hormones, including gonadotropin-releasing hormone, luteinizing hormone, follicle-stimulating hormone, estrogen, progesterone, and testosterone. These changes can slow down functions in the hypothalamus, the region of the brain responsible for hormone release.

Additionally, a low level of leptin, a hormone produced by fat cells, may also contribute to amenorrhea and irregular menstruation. Research suggests that women need a certain level of leptin to maintain normal menstrual function. A very low-carb diet may suppress leptin levels and interfere with its ability to regulate reproductive hormones, especially in underweight or lean women.

A 2003 study found that 45% of teenage girls following a ketogenic diet to treat epilepsy experienced menstrual problems, with 6% experiencing amenorrhea during the six-month study period.

Thyroid function

The thyroid gland produces two crucial hormones, thyroxine (T4) and triiodothyronine (T3). These hormones are necessary for various bodily functions, including breathing, heart rate, the nervous system, body weight, temperature control, cholesterol levels, and the menstrual cycle.

While some studies suggest that the keto diet has no adverse effects on thyroid function and may even be beneficial, others indicate that consuming too few carbohydrates can lower thyroid hormone levels. A very low-carb diet may cause a drop in thyroid function, resulting in fatigue, weight gain, and low mood.

Estrogen and cortisol

As weight drops, so do estrogen levels. A rapid weight loss of 17 pounds led to a decrease in estrogen hormone levels, according to one study. Estrogen deficiency can cause infertility, vaginal atrophy, and an increased risk of osteoporosis.

Studies suggest that low-carb diets may increase cortisol, the stress hormone. Long-term elevated cortisol levels can lead to various health issues, including weight gain, anxiety, depression, and an increased risk of heart disease.

Other considerations

The keto diet may also affect other hormones, such as serotonin, progesterone, and insulin. These hormonal changes can cause problems like acne or worsen existing conditions like endometriosis or PCOS. The increase in cortisol and estrogen could also worsen symptoms for women in perimenopause or menopause.

Additionally, the keto diet's restriction of complex carbs and fiber can put stress on the body, leading to weight gain. The diet's high-fat content may also lead to increased estrogen production, which can suppress thyroid function and result in weight gain.
