Keto's Fame: Does It Work Or Is It Just Hype?

The ketogenic diet is a low-carb, high-fat diet that has been endorsed by several celebrities. It involves drastically reducing your carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it burns fat for energy instead of glucose. While the keto diet has been shown to have health benefits, including short-term weight loss, it is not suitable for everyone and can have side effects such as keto flu, which includes symptoms like irritability and headaches.

Keto can help with weight loss

The keto diet can be an effective way to lose weight and lower the risk of certain diseases. It involves eating a very low amount of carbohydrates and replacing them with fat to help the body burn fat for energy. This reduction in carbs puts the body into a metabolic state called ketosis, which can lead to weight loss.

Research has shown that the keto diet may be as effective for weight loss as a low-fat diet. One review of 13 studies found that following a very low-carb, ketogenic diet was slightly more effective for long-term weight loss than a low-fat diet. People who followed the keto diet lost an average of 2 pounds (0.9 kg) more than the group that followed a low-fat diet. Another study in 34 older adults found that those who followed a ketogenic diet for 8 weeks lost nearly five times as much total body fat as those who followed a low-fat diet.

The keto diet can also help reduce appetite, which may lead to eating less food and contribute to weight loss. Additionally, the increased ketones, lower blood sugar levels, and improved insulin sensitivity that result from the keto diet may also play a key role in weight loss.

While the keto diet can be an effective tool for weight loss, it is important to note that it is a restrictive diet and may be challenging to follow. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as the keto diet.

It can reduce seizures in children with epilepsy

The keto diet has been used to reduce seizures in children with epilepsy since the 1920s. While the mechanism by which the keto diet regulates seizures is not well understood, several theories have been proposed.

One theory is that ketones, which are produced when the body uses fat for energy, provide a more stable source of energy for the brain. Another theory is that ketones produce fewer free radicals, which are chemicals that cause inflammation in the brain and are linked to Alzheimer's and strokes.

The keto diet is typically recommended by doctors for children whose seizures have not responded to medication. It is a strict diet that requires careful measurement and monitoring of food intake. The diet is high in fat, moderate in protein, and very low in carbohydrates. The typical ratio is about 4 grams of fat for every 1 gram of carbohydrates and protein.

The keto diet has been shown to be effective in reducing seizures in children with epilepsy. Studies have found that about 40% to 50% of children who start the keto diet experience a 50% reduction in seizures. Additionally, about 10% to 20% of children achieve more than a 90% reduction in seizures, and some children become seizure-free.

While the keto diet can be effective, it is not without risks and side effects. It can lead to nutrient deficiencies, constipation, low appetite, nausea, and sluggishness. It is also important to note that the keto diet should be closely monitored by healthcare providers and should not be attempted without medical supervision.

It can help manage type 2 diabetes

The ketogenic diet can be beneficial for people with type 2 diabetes. The diet is high in fat and low in carbs, which can change the way the body stores and uses energy, thus easing diabetes symptoms.

The keto diet involves the body converting fat, instead of sugar, into energy. This can lead to lower blood glucose (sugar) levels and a reduced need for insulin.

A 2013 review reported that a ketogenic diet can lead to more significant improvements in blood sugar control, A1C, weight loss, and discontinued insulin requirements than other diets. A 2017 study also found that the keto diet outperformed a conventional, low-fat diabetes diet over 32 weeks regarding weight loss and A1C.

In a 2019 study, people with type 2 diabetes who followed a ketogenic diet for two years were able to decrease their use of diabetes medications by 81%.

However, it is important to note that the keto diet does come with risks and should be discussed with a doctor before making any drastic dietary changes.

It can help lower the risk of heart disease

The ketogenic diet has been associated with an increased risk of heart disease, but there is evidence to suggest that it can also help lower the risk.

The ketogenic diet is a low-carbohydrate, high-fat diet that has been used to help reduce the frequency of epileptic seizures in children. It has also been used for weight loss, but it is recommended as a short-term dietary change to jump-start weight reduction.

The diet involves reducing carbohydrate intake to less than 20-50 grams per day and getting 60-80% of daily calories from fat. This can lead to a state of ketosis, where the body burns fat for energy instead of glucose.

While the ketogenic diet has been linked to an increase in "bad" LDL cholesterol, which is a risk factor for heart disease, there is also research suggesting that the diet can have a beneficial effect on the blood lipid profile.

One study found that a ketogenic diet showed a greater reduction in total cholesterol, triglycerides, and LDL cholesterol, while increasing HDL cholesterol, compared to a standard diabetes diet. Another study found that a ketogenic diet enriched in omega-3 fatty acids had an additional improved health-promoting effect.

In addition, the ketogenic diet has been shown to have anti-inflammatory properties, which may also contribute to a reduced risk of heart disease.

However, it is important to note that the ketogenic diet may not be suitable for everyone, especially those with existing heart disease or high cholesterol. It is always recommended to consult with a doctor or healthcare provider before starting any new diet.

It can help manage polycystic ovary syndrome

The polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age, affecting approximately 4% of women. It is associated with obesity, hyperinsulinemia, and insulin resistance.

A low-carbohydrate, ketogenic diet can help manage PCOS by improving insulin resistance and reducing weight. A pilot study involving 11 women with PCOS found that a low-carbohydrate, ketogenic diet led to significant improvements in body weight, percent free testosterone, LH/FSH ratio, and fasting serum insulin over a 24-week period.

Another study involving 14 women with PCOS who followed a ketogenic diet for 12 weeks showed a significant decrease in blood glucose and insulin levels, as well as a significant improvement in HOMA-IR (a measure of insulin resistance). The luteinizing hormone (LH)/follicle-stimulating hormone (FSH) ratio, total and free testosterone, and blood levels of dehydroepiandrosterone sulfate (DHEAS) were also significantly reduced.

The ketogenic diet has been shown to activate adenosine monophosphate-activated protein kinase (AMPK) and silent mating type information regulation 2 homologue 1 (SIRT1), which positively affect glucose homeostasis and improve insulin sensitivity.

While the ketogenic diet has shown promising results in managing PCOS, more research is needed to substantiate the evidence and determine the ideal dietary pattern or macronutrient composition for weight reduction in women with PCOS.
