Keto's Future: Fad Or Mainstream Diet?

The ketogenic diet has been touted as the next big thing in nutrition, but will it become mainstream? The keto diet is a low-carb, high-fat, moderate-protein eating plan that has been around since the early 1920s. It was originally developed as a treatment for epilepsy, but in recent years, it has gained popularity as a weight-loss tool. The diet is based on the idea of achieving ketosis, a state in which the body burns fat instead of glucose for energy. While keto has its supporters, there are also concerns about its high fat content and potential health risks. Some experts warn that the long-term effects of the diet are unknown, and it may not be a sustainable way to lose weight. Despite this, the keto diet has seen a surge in popularity, with celebrity endorsements and a growing market for keto products. So, will keto go mainstream? Only time will tell, but it seems to be well on its way.

The history of keto

The ketogenic diet, or keto, has become increasingly popular in recent years, but its history goes back to the early 20th century when it was used as a treatment for epilepsy. Here is a brief history of the keto diet:

The Early Days

The idea of fasting for health benefits is not new. Ancient Greek physicians, including Hippocrates, advocated for fasting to treat various diseases, including epilepsy. In the early 20th century, a group of Parisian physicians successfully treated epilepsy patients using prolonged fasts. This practice was also recorded in the Bible.

The 1920s: The Birth of Keto

In 1921, R.T. Woodyatt made a pivotal observation. He noted that the same metabolic changes occurred in people who were starving as in those who were eating a low-carb, high-fat diet. Around the same time, Dr. Russell Wilder at the Mayo Clinic proposed that the benefits of fasting could be obtained with a high-fat, low-carb diet. This diet, which he called "ketogenic," aimed to mimic the effects of fasting by depleting the body of sugar. The diet was widely used throughout the 1920s and 1930s to treat epilepsy, particularly in children, and was found to be effective in reducing seizures.

The 1930s-1990s: Decline of Keto

With the discovery of novel anti-seizure medications in 1938, the focus shifted from dietary treatments like keto to pharmaceutical interventions. As a result, fewer dietitians were trained in the use of the keto diet, and it gradually fell out of favour. By the 1990s, keto was all but forgotten, and those who studied it considered it a historical curiosity rather than a viable medical treatment.

The 1990s: Revival of Keto

In October 1994, the TV show Dateline aired an episode about a two-year-old boy named Charlie, who had severe epilepsy. Charlie's seizures were successfully treated with the keto diet at John Hopkins Hospital, and this sparked a resurgence of interest in the dietary approach. The child's father formed The Charlie Foundation and directed the 1997 film "First Do No Harm" starring Meryl Streep, which further popularized the diet.

2000s-Present: Keto Goes Mainstream

In the 2000s, the Atkins diet, a low-carb diet similar to keto, gained popularity. Around the same time, a 2013 study published in "Science" found that ketones activated powerful antioxidant and anti-inflammatory genes, suggesting that keto could slow ageing and prevent age-related diseases. This caught the attention of biohackers and lifestyle gurus, who began experimenting with the diet and sharing their experiences. Celebrities like Kim Kardashian and Halle Berry also jumped on the keto bandwagon, further contributing to its mainstream appeal.

Today, keto is a thriving industry, with a growing number of keto-friendly products, books, and even movies. While it remains controversial among medical professionals due to its high-fat content, keto continues to gain traction as a weight-loss strategy and a potential treatment for various health conditions.

Keto's popularity

Ketos's Popularity

Keto, a high-fat, moderate-protein, and low-carbohydrate diet, has become increasingly popular in recent years. In 2018, it was the most-Googled diet of the year, marking a peak in the growing shift towards low-carb eating. The diet has been endorsed by celebrities like Halle Berry, Kim Kardashian, and Oprah, and companies like Chipotle, BurgerFi, and SlimFast have cashed in on the trend by offering keto-friendly options. The global keto diet market was valued at $9.57 billion in 2019 and is expected to grow to $17.8 billion by 2026.

History of Keto

Keto was first developed in the early 1920s by clinicians and scientists at the Mayo Clinic as a treatment for epilepsy in children. The diet fell out of use in the late 1930s with the discovery of novel anti-seizure medications. However, it regained some popularity in the early 1990s after a national news story about a two-year-old boy with epilepsy who was successfully treated with the keto diet.

Weight Loss Tool

Today, keto is considered a powerful weight-loss tool, although it didn't start out that way. Interest in keto for weight loss can be traced back to the 1970s when Dr. Robert Atkins published his first diet book, "Dr. Atkins' Diet Revolution: The High Calorie Way to Stay Thin Forever." The first weeks of his eponymous diet centred on eating fat and very few carbs to induce ketosis, a state in which the body burns fat instead of glucose.

Health Benefits and Risks

In addition to weight loss, keto has been associated with other health benefits, such as reduced hunger and increased focus. It has also been shown to be effective in managing type 2 diabetes, with some research indicating that it can put the condition into remission. However, there are also risks associated with the keto diet, including nutrient deficiency, liver and kidney problems, constipation, and fuzzy thinking and mood swings. The high-fat content of the diet, particularly saturated fats, has also been linked to an increased risk of heart disease.

Mainstream Acceptance

While keto has gained significant popularity in recent years, it is still controversial and has not achieved full mainstream acceptance. The diet continues to be criticised by many health professionals, and there is a lack of long-term evidence on its effects on the body. However, with growing consumer interest in clean eating and the relationship between diet and health, it seems likely that keto will continue to gain traction and become more widely accepted.

The science behind keto

The ketogenic diet (keto) is a high-fat, low-carb diet. It involves eating very limited carbohydrates, typically less than 50 grams per day, which is a drastic reduction for most people. This forces the body to burn fat for fuel, as it is no longer getting energy from carbohydrates. This state is called ketosis, where the body breaks down stored fat into molecules called ketone bodies, which are used to generate energy.

The keto diet is not a new concept. It was first developed in the 1920s by clinicians and scientists at the Mayo Clinic as a treatment for drug-resistant epilepsy, especially in children. However, the origins of the diet can be traced back to antiquity, as fasting to control epileptic seizures was mentioned in the Bible, and Hippocrates recommended it as the only treatment option for epilepsy. In the early 20th century, Parisian physicians successfully treated epilepsy with prolonged fasts.

In 1921, R.T. Woodyatt noticed that people who fasted and those eating a low-carb, high-fat diet experienced the same metabolic changes. Simultaneously, Dr Russell Wilder at the Mayo Clinic proposed a high-fat, low-carb diet, which he called the ketogenic diet, as a way to mimic the effects of fasting and reduce seizures. The keto diet was widely used throughout the 1920s and 1930s, with thousands of children experiencing successful treatment. However, with the discovery of novel anti-seizure medications, the focus shifted away from the keto diet, and it fell out of favour.

In the 1960s and 70s, Dr Robert Atkins popularised a low-carb diet for weight loss, with the first phase being very similar to keto. The keto diet itself began to gain traction for weight loss in the 2010s, with a 2013 study finding that ketones activate powerful antioxidant and anti-inflammatory genes, suggesting potential anti-ageing and disease prevention benefits. This sparked interest among biohackers, and the diet soon gained popularity, with celebrities like Kim Kardashian and Halle Berry endorsing it.

While keto has been shown to be effective for weight loss and blood sugar control in type 2 diabetes, there are some concerns about its long-term effects, especially regarding heart health. The diet's high saturated fat content can raise cholesterol levels, and there is a lack of long-term research on its effects on diabetes and high cholesterol. Additionally, the keto diet can be challenging to adhere to due to its restrictive nature, and it may not be suitable for everyone, especially those at risk for heart disease or with kidney disease.

Despite these concerns, the keto diet continues to be a popular weight-loss tool, and it has sparked interest in the scientific community, with an increasing number of studies being conducted on its potential benefits and risks.

The keto diet's health benefits and risks

The ketogenic diet has been around since the 1920s, but it has recently become a mainstream movement. The keto diet is a low-carb, high-fat diet that has been used to help treat epilepsy in children. More recently, it has been adopted as a weight-loss tool.

Health Benefits

The keto diet has been linked to several health benefits, including:

• Weight loss: The keto diet can lead to a reduction in appetite, which regulates calorie intake and results in weight loss.
• Improved insulin sensitivity: The keto diet has been shown to reduce hyperinsulinemia and improve insulin sensitivity, which is beneficial for individuals with type 2 diabetes.
• Reduced seizures: The keto diet is an effective treatment for reducing the frequency of epileptic seizures, especially in children.
• Improved blood sugar control: The keto diet may help lower blood sugar levels, which is beneficial for individuals with diabetes.

Health Risks

However, there are also several health risks associated with the keto diet:

• Nutrient deficiencies: The keto diet restricts fruits, vegetables, grains, and legumes, which can lead to deficiencies in micronutrients such as selenium, magnesium, phosphorus, and vitamins B and C.
• Heart disease: The high intake of saturated fat on the keto diet can increase "bad" LDL cholesterol, which is a risk factor for heart disease.
• Liver problems: The large amount of fat in the keto diet can overload the liver and worsen existing liver conditions.
• Kidney problems: The kidneys may be overloaded by the high protein intake associated with the keto diet.
• Constipation: The keto diet is low in fibrous foods, which can lead to constipation.
• Fuzzy thinking and mood swings: Low-carb diets like keto may cause confusion and irritability due to the brain's preference for sugar from carbohydrates as an energy source.
• Social isolation and disordered eating: Strict diets like keto can lead to social isolation and may trigger disordered eating behaviours.
• Short-term side effects: Individuals starting the keto diet may experience "keto flu," which includes symptoms such as fatigue, headache, dizziness, nausea, vomiting, constipation, and low exercise tolerance.

Keto's future

The ketogenic diet has been around since the early 1920s, but it has recently gained popularity, with Google searches for the diet increasing nearly eightfold in the past three to five years. In 2018, keto was the most-Googled diet of the year, and in 2020, it was the most Googled diet in the United States. The diet has also been discussed by celebrities, health magazines, and documentaries, and the global ketogenic diet market was valued at $9.57 billion in 2019.

The keto diet is a high-fat, moderate-protein, and low-carbohydrate diet. It makes the body produce ketones, which are used as an alternative fuel when blood sugar levels are low. Ketones are produced in the liver from fat, making ketogenic a popular approach to weight loss. The diet is considered safe when done right, but it is controversial due to its high emphasis on saturated fat and low intake of nutrients, which may affect heart health over time.

The future of keto is uncertain, but it seems to be heading towards the mainstream. The diet has gained traction due to celebrity endorsements, the availability of keto-friendly products, and increasing scientific interest. However, it still faces opposition from the medical community, with concerns about its long-term effects on health.

In conclusion, keto's future is difficult to predict, but it seems to be heading towards greater mainstream acceptance. However, its long-term sustainability and health effects are still uncertain, and further research is needed to clarify its potential benefits and risks.
