Keto's End: When Will The Fad Diet Finally Fade?

The ketogenic diet, or keto, is a low-carb, high-fat diet that has been around for a while. It was originally used to treat epilepsy in the 1920s, but in recent years, it has become a popular weight-loss trend. In 2020, keto was the most Googled food-related topic globally, with 25.4 million searches. The keto trend is expected to continue growing, with the market predicted to reach a global value of $15.6 billion by 2027. However, like all dietary trends, it is subject to the possibility of fading out. So, when will the keto trend die?

Keto's popularity is due to its promise of quick weight loss without hunger

The ketogenic diet, or keto, is a low-carb, high-fat diet that has been around since the 1920s. While it was originally used to treat epilepsy, keto has gained popularity in recent years as a weight-loss tool. The keto diet is appealing to many because it allows people to eat high-fat foods they enjoy, such as red meats, fatty fish, nuts, cheese, and butter, while still losing weight.

Keto's popularity can be attributed to its promise of quick weight loss without hunger. The high-fat content of the diet helps people feel full and satisfied, making it easier to stick to than low-fat diets. In addition, the diet can lead to a state of ketosis, where the body burns fat for fuel instead of glucose, resulting in weight loss. This has led to an increase in keto-friendly products and supplements, with the ketogenic diet market predicted to reach a global value of $15.6 billion USD by 2027.

The keto diet has been popularized by celebrities and social media influencers, who have shared their success stories and dramatic before-and-after photos. This has created a viral effect, with people eager to try the diet for themselves. The promise of quick weight loss and the ability to eat high-fat foods have been a winning combination for keto's popularity.

However, it is important to note that keto is not without its drawbacks. The stringent food restrictions can make the diet hard to stick to long-term, and the lack of carbohydrates can lead to vitamin and mineral deficiencies. Nutrition experts caution that the emphasis on saturated fat and lack of nutrients may affect heart health over time. As a result, it is recommended to consult a doctor or dietitian before starting the keto diet to ensure it is right for your individual needs.

The diet is high-fat, low-carb, and pushes the body into a state of ketosis

The ketogenic diet, or keto, is a low-carbohydrate, high-fat diet. It is considered an ultra-low-carb diet, with less than 50 grams of carbs per day, or even as few as 20 grams. This is in stark contrast to the average American diet, where breakfast alone can contain 50 grams of carbs.

The keto diet is designed to push the body into a state of ketosis, where the body burns fat for fuel instead of glucose. In a normal metabolic state, carbohydrates are broken down into glucose and absorbed through the small intestine, then travel to the liver and are stored as glycogen. When in ketosis, the body's glycogen stores are depleted, and the liver produces ketone bodies from fat, which are then used as a fuel source.

To achieve this state, the keto diet recommends getting 70-80% of calories from fat, 15-30% from protein, and only 5-10% from carbohydrates. This means a typical keto diet includes foods such as fatty fish (like salmon), cheese, yogurt, butter, oils, and full-fat dairy products.

The keto diet has gained popularity due to its promise of quick weight loss and reduced hunger. It has also been linked to various health benefits, including improved insulin sensitivity, reduced triglycerides and blood pressure, and improved blood lipid levels. Additionally, it was originally developed to treat severe epilepsy and has been shown to have therapeutic benefits for this condition.

However, it is important to note that the keto diet can be restrictive and may not be suitable for everyone. It can be challenging to stick to in the long term, and it may cause unwanted side effects like constipation and the keto flu, which can include headaches, fatigue, and irritability. It is also important to be mindful of the types of fat consumed, as saturated and trans fats can increase bad cholesterol levels.

While the keto diet has been a trending topic and has helped many people achieve their health and weight loss goals, it is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as keto.

The keto diet was originally used to treat epilepsy

The diet was developed by Mayo Clinic doctor Russell Wilder, who started experimenting with a fat-centric diet that mimicked the effects of fasting by depleting the body of sugar. Wilder tested his "ketogenic" diet on people with epilepsy, and it has been an effective treatment for seizures ever since. The diet is usually prescribed to children whose seizures have not responded to several different seizure medications.

The ketogenic diet is carefully monitored by a dietitian, who measures calories, fluids, and proteins. Foods are weighed and measured, and no other sources of carbohydrates can be eaten. The diet is also supervised by a neurologist, who monitors medications and overall benefits. The diet is typically started in the hospital, with the child fasting (except for water) under close medical supervision for 18-24 hours before the diet is started.

Several studies have shown that the ketogenic diet does reduce or prevent seizures in many children whose seizures could not be controlled by medications. Over half of the children who go on the diet have at least a 50% reduction in the number of their seizures, and some children, usually 10-15%, even become seizure-free. The diet can also have other positive effects, such as increased alertness, awareness, and responsiveness.

The ketogenic diet is not recommended as a primary anti-seizure option because patients are often averse to drastic changes in their food intake or have trouble staying on the diet due to its strict requirements and potential side effects like nausea, constipation, and fatigue. However, for those who can tolerate it, the keto diet has proven to be an effective treatment for epilepsy.

It is also effective for type 2 diabetes and potentially other health conditions

The keto diet is a high-fat, low-carbohydrate diet that can be effective for people with type 2 diabetes. The diet forces the body to use fat, instead of glucose, for energy, which can help to lower blood sugar levels. This is particularly beneficial for people with type 2 diabetes, as their bodies either do not produce insulin or do not respond effectively to it, leading to high blood sugar levels.

Several studies have shown the benefits of the keto diet for people with type 2 diabetes. A 2008 study found that, after 24 weeks, participants with type 2 diabetes and obesity who followed a keto diet saw greater improvements in glycemic control and medication reduction compared to those on a low-glycemic diet. 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. Furthermore, a 2017 study found that the keto diet outperformed a conventional, low-fat diabetes diet over 32 weeks in terms of weight loss and A1c.

However, it is important to note that the keto diet is highly restrictive and can be challenging to follow in the long term. It is recommended that people with type 2 diabetes consult a healthcare professional before starting the keto diet, as it may not be suitable for everyone. Additionally, the keto diet should not be followed for longer than 12 months, and it is crucial to monitor blood sugar and ketone levels to ensure the diet is not causing any adverse effects.

While the keto diet has shown promise for type 2 diabetes management, it is not a cure. It may be more beneficial for people with type 2 diabetes to focus on adopting a balanced diet with a variety of fresh fruits and vegetables and spreading out carbohydrate intake evenly throughout the day. Consulting a healthcare professional can help individuals with type 2 diabetes choose the best diet plan for their specific needs and preferences.

There are concerns about the long-term health effects of keto

The ketogenic diet, or keto, is a low-carb, high-fat diet that has gained popularity in recent years. While keto can lead to quick weight loss and has been shown to be effective in treating seizures in people with epilepsy, there are concerns about its long-term health effects.

Firstly, the keto diet restricts fruits, whole grains, and starchy vegetables, which are good sources of vitamins, minerals, antioxidants, and fiber. This can lead to vitamin and mineral deficiencies, affecting gut health and increasing the risk of chronic diseases such as heart disease. Indeed, studies have found that people on keto diets have an increased risk of developing heart disease, high cholesterol, kidney failure, and Alzheimer's disease.

Secondly, the high-fat content of the keto diet, especially saturated fats, can increase the risk of heart disease. The body is in a more acidic state during ketosis, which may limit its ability to perform at peak levels. Additionally, the strict nature of the diet can make it difficult to stick to, leading to weight regain and a higher risk of early death.

Furthermore, keto diets have been linked to an increased risk of cancer, diabetes, and gestational diabetes. The high protein intake can also be dangerous for people with chronic kidney disease, as it places excess stress on the kidneys.

Finally, the keto diet may affect athletic performance. A study found that participants performed worse on high-intensity exercises after being on a ketogenic diet for four days.

In conclusion, while keto may lead to quick weight loss, there are concerns about its long-term sustainability and potential negative health effects. More research is needed to fully understand the impact of this diet on the body over extended periods.
