Keto Diet: Does Dr. Mercola's Method Really Work?

The ketogenic diet, or keto diet, is a popular eating pattern that involves lowering carbohydrate intake to minimal levels and increasing the consumption of meals higher in fat and protein. While the keto diet has attracted many followers, some people have also decided to quit it. One such person is Dr. Joseph Mercola, who initially promoted the keto diet and even wrote a book called KetoFast: Rejuvenate Your Health with a Step-by-Step Guide to Timing Your Ketogenic Meals. However, Dr. Mercola eventually decided to quit the keto diet due to concerns about mortality and metabolism.

Dr. Mercola quits keto due to mortality and metabolism concerns

Dr. Mercola, once a staunch advocate of the keto diet, has recently abandoned it due to concerns about mortality and metabolism risks. In a video titled "Dr. Mercola Quits Keto Diet. Why?" by Mic the Vegan, Dr. Mercola explains his decision, citing a study from the Journal of Internal Medicine that found a significant difference in mortality rates between two groups. The study, involving 400,000 participants over 20 years, revealed that the keto diet, a low-carb high-fat diet, increased mortality rates by 30%, while a low-fat high-carb diet decreased mortality.

Dr. Mercola emphasizes the importance of sugar for brain function, stating that without it, one can experience a hypoglycemic coma and even death. He also acknowledges the role of sugar in maintaining healthy cholesterol levels, as the body may break down muscle to create glucose, which can lead to weight loss that is mostly lean mass rather than fat. Additionally, Dr. Mercola highlights the potential impact of elevated cortisol levels from the keto diet on aging, as well as the association between diets high in animal fat and cholesterol with cardiovascular disease and atherosclerosis.

The speaker in the video, Mic the Vegan, expresses concerns about Dr. Mercola's transition, speculating that it may be motivated by his desire to sell new dietary products or approaches. They also criticize Dr. Mercola for not publicly acknowledging the health risks associated with the keto diet and continuing to promote his keto books and products.

In response to his departure from the keto diet, Dr. Mercola now emphasizes a balanced dietary approach, focusing on health and happiness rather than weight loss obsession. He addresses the keto-related mental health and undernutrition issues that can arise from restrictive diets. Additionally, Dr. Mercola identifies linoleic acid, commonly found in vegetable oils, as a contributor to chronic diseases and recommends a diet low in vegetable oils and high in natural fats for improved health outcomes.

The keto diet's restrictions can make it hard to follow

The keto diet has gained a lot of popularity, with many people advocating for its benefits. However, it is not without its challenges and restrictions, which can make it difficult to follow and lead to negative health outcomes.

The keto diet is a high-fat, low-carbohydrate diet that promotes the use of ketone bodies as fuel. While this dietary approach has attracted many followers, the restrictions can be quite limiting and hard to adhere to in the long term. The diet requires a significant reduction in carbohydrate intake, which means cutting out or strictly limiting foods such as bread, pasta, rice, potatoes, and sugar. For many people, these are staple foods that form a large part of their daily meals, so eliminating them can be challenging and may lead to feelings of deprivation.

In addition, the keto diet often involves a high consumption of animal-based products, which can be problematic for those who prefer plant-based diets or have ethical concerns about consuming large quantities of meat and dairy. The high-fat content of the keto diet may also be a concern for those with health issues such as high cholesterol or a family history of heart disease. As such, the keto diet may not be suitable or sustainable for everyone, and it is important to consider individual needs and preferences.

Furthermore, the keto diet can be socially restrictive. Eating out or attending social events where food is involved can become challenging and may require careful planning. The diet's restrictions can make it difficult to find suitable meal options when dining out, and special accommodations may be needed. This can lead to feelings of isolation or inconvenience, especially when sharing meals with others.

The keto diet's restrictions can also impact mental health. For some individuals, the strict rules and limitations can lead to increased stress, anxiety, or a negative relationship with food. The diet's focus on calorie restriction and weight loss can contribute to disordered eating patterns and a negative body image. It is important to prioritize mental health and well-being, and the keto diet may not provide the flexibility or balance needed to support this.

Overall, while the keto diet may work for some people, its restrictions can make it challenging to follow and maintain. It is important to consider individual needs, preferences, and health goals when deciding whether to adopt a restrictive diet like keto. Sustainable and balanced dietary patterns that include a variety of foods from all food groups may be a more realistic and enjoyable approach for long-term health and well-being.

Dr. Mercola's history of pseudoscientific claims

Dr. Joseph Michael Mercola is an American alternative medicine proponent, osteopathic physician, and internet business personality. He has a long history of making pseudoscientific claims and marketing unproven dietary supplements and medical devices.

Mercola operates the website Mercola.com, which he claims is the most popular alternative health website on the internet. The site promotes disproven health ideas, such as the notion that homeopathy can treat autism and that vaccinations have hidden detriments to human health. Mercola has also spread misinformation about the COVID-19 virus and vaccines, becoming the "chief spreader of coronavirus misinformation online," according to researchers. He has published over 600 articles on Facebook that cast doubt on COVID-19 vaccines, and his claims have been widely echoed on other social media platforms.

In addition to his website, Mercola has authored two books, "The No-Grain Diet" and "The Great Bird Flu Hoax," which have been listed on the New York Times bestseller list. In "The Great Bird Flu Hoax," Mercola dismisses medical concerns over an avian influenza pandemic, asserting that the government, big business, and the mainstream media have conspired to promote the threat of avian flu to accrue money and power.

Mercola has also been criticized for his dietary recommendations, which often contradict mainstream dietary advice. For example, he has advocated for the elimination of genetically modified foods from the market and has claimed that microwaving food alters its chemistry, despite consensus that microwaving does not adversely affect nutrient content. He has also promoted the idea that consuming animal fat and raised cholesterol can lead to increased mortality and raised concerns about the keto diet's potential impact on metabolism and mortality.

Mercola's medical claims have been criticized by the medical, scientific, regulatory, and business communities. The U.S. Food and Drug Administration (FDA) has repeatedly warned Mercola and his company about making illegal claims regarding the ability of their products to detect, prevent, and treat diseases.

The importance of sugar for brain function

The brain relies on glucose as its primary source of fuel. As the brain accounts for around 2% of the body's weight, it consumes about 20% of the body's glucose-derived energy. Glucose is essential for physiological brain function, as it provides the fuel for brain cells (neurons) and generates ATP, which is the foundation for neuronal and non-neuronal cellular maintenance, as well as the generation of neurotransmitters.

The Impact of Sugar on the Brain

The effects of sugar on the brain include:

• Impaired cognitive skills and decreased self-control: Sugar stimulates a craving for more.
• Drug-like effects in the reward centre of the brain: Sweet foods produce addiction-like effects, leading to a loss of self-control, overeating, and weight gain.
• Sugar impacts the brain's reward response: Eating sweet foods activates the brain's reward system, reinforcing behaviours and making it more likely for them to be repeated.
• Sugar causes addiction-like responses: Overeating alters the brain's reward system, leading to tolerance and a diminished reward response.
• Sugar has effects on memory: A high-sugar diet can lead to a reduction of newborn neurons in the hippocampus, a key memory centre in the brain.
• Sugar has effects on mood: Elevated blood glucose can lead to compromised emotional processing, increased anxiety, and a higher risk for depression.
• Sugar intake hinders mental capacity: Elevated blood glucose harms blood vessels and can lead to damage to blood vessels in the brain, causing retinopathy.

Protecting Your Brain from Sugar

While sugar is essential for brain function, excessive sugar consumption can have negative impacts on the brain and the body. The World Health Organization advises limiting added sugar intake to 5% of daily calorie intake (around 25 grams or six teaspoons). Reducing sugar intake, engaging in physical exercise, and consuming foods rich in omega-3 fats can help protect the brain.

Dr. Mercola's keto diet book

Dr. Joseph Mercola is a well-known name in the keto diet world, having authored the book "KetoFast: Rejuvenate Your Health with a Step-by-Step Guide to Timing Your Ketogenic Meals." Published in 2019, the book provides a detailed guide to following a ketogenic diet, with a specific focus on meal timing.

The keto diet, short for the ketogenic diet, is a popular eating pattern that involves a significant reduction in carbohydrate intake and a corresponding increase in fat consumption. The goal is to shift the body's primary energy source from glucose (derived from carbohydrates) to ketones, which are produced by breaking down fat. This shift in metabolism is known as ketosis.

Dr. Mercola's book, "KetoFast," likely provides a comprehensive overview of the keto diet, including the benefits and challenges of adopting this way of eating. It may also offer specific guidance on how to time ketogenic meals to maximize the potential health benefits. However, it's important to note that since the book's publication, Dr. Mercola has distanced himself from the keto diet due to concerns about its potential impact on mortality and metabolism.

In particular, Dr. Mercola emphasizes the importance of sugar for brain function, arguing that its absence can lead to a hypoglycemic coma and even death. He also acknowledges the role of cholesterol, which can be affected by a diet high in animal fat, as another potential risk factor for increased mortality. These concerns led Dr. Mercola to step away from promoting the keto diet, despite his previous endorsement and the existence of his keto-related products and literature.
