Renowned individuals such as Halle Berry maintain that a traditional diet helps her manage diabetes, control weight, and boosts energy levels. Celebrities like Kourtney Kardashian and LeBron James also endorse this diet.
However, it's not just celebrities...
Studies indicate that this diet not only aids in weight loss, diabetes management, and enhancing physical performance but also reduces the risk of heart disease and potentially inhibits tumor growth.
Originally developed for treating epileptic seizures, researchers at Stanford Medicine explored whether it could also have a positive impact on mood. Subsequently, they initiated a unique trial to investigate.
The ketogenic diet, commonly referred to as the keto diet, is low in carbohydrates, moderate in protein, and high in fat. It is also recognized as metabolic therapy as it reduces the body's reliance on glucose for energy and instead utilizes ketone bodies derived from fat for fuel.
Recent research indicates that psychiatric disorders like schizophrenia and bipolar ailment may be linked to metabolic (energy) dysfunction. Some medical professionals believe that psychiatric disorders are not solely mental issues but rather metabolic problems that trigger mental health issues.
Evidence supporting this theory stems from the high occurrence of metabolic syndrome in individuals with severe mental illnesses. This syndrome elevates the risk of Type-2 diabetes and conditions impacting the heart and blood vessels, leading to premature cardiovascular disease and shortened lifespan for affected individuals.
Psychiatric medications, which carry metabolic side effects like insulin resistance and obesity, are sometimes ineffective in managing mental conditions or result in unpleasant side effects, prompting patients to discontinue treatment. Introducing an alternative brain fuel could potentially influence metabolism in a way that enables patients to take psychiatric medication without adverse effects.
Moreover, the diet is believed to have various positive effects on the brain, including reducing inflammation, minimizing free radicals, and stabilizing brain functions, all of which contribute to enhancing mental health, mood, and more.
Aside from its well-documented success in controlling epileptic seizures long-term, limited case studies, all with positive outcomes, have explored its application in schizophrenia. Consequently, Shebani Sethi, MD, an associate professor of psychiatry and behavioral sciences at Stanford, conducted a pilot trial involving 21 patients with either schizophrenia or bipolar disorder to examine the ketogenic diet's efficacy.
All participants exhibited at least one metabolic issue, with 29 percent meeting the criteria for metabolic syndrome, defined by having at least three of the following conditions: abdominal obesity, elevated triglycerides, low HDL cholesterol, high blood pressure, and raised fasting glucose levels.
The research team instructed all participants to continue their prescribed medications and adhere to a ketogenic diet consisting of approximately 10 percent carbohydrates, 30 percent protein, and 60 percent fat. They were provided with keto-friendly meal suggestions, cookbooks, and access to a health coach.
The trial's outcomes were highly positive, not only in terms of mood and mental health improvements.
At the trial's conclusion, 14 patients fully adhered to the diet, six were partially compliant, and only one discontinued the diet. Among those who strictly followed the diet, the results included:
Furthermore, a significant 75 percent noted a meaningful enhancement in their mental health, as evaluated by a psychiatric assessment of mental disorders, with an average improvement of 31 percent.
Participants who were partially compliant with the diet also experienced similar benefits but to a lesser degree, indicating a correlation between adherence level and positive outcomes.
Dr. Sethi expressed enthusiasm over the results, stating, “It's very promising and encouraging that individuals can regain some control over their conditions beyond conventional care.
“We're observing substantial changes. Even for those on antipsychotic medications, we can still reverse obesity, metabolic syndrome, and insulin resistance. I find this very uplifting for patients who also reported enhancements in their energy levels, sleep patterns, mood, and overall quality of life. They feel healthier and more optimistic.”
Years before the study, Dr. Sethi introduced the term metabolic psychiatry, a novel discipline that addresses mental health through an energy conversion lens.
Brain metabolic deficiencies are believed to overstimulate neurons. By enhancing brain metabolism, the ketogenic diet can alleviate this issue, similar to its effects on the body's metabolism.
“Improving overall metabolic health will likely benefit brain health as well,” Sethi remarked. “The ketogenic diet offers ketones as an alternative energy source to glucose for a brain suffering from energy dysfunction.”
For those interested in adopting the ketogenic diet utilized in this trial, participants were advised to avoid bread and pasta and concentrate on unprocessed foods. Carbohydrate intake was limited to 20 grams per day (excluding fiber), along with a recommended consumption of a cup of non-starchy vegetables, two cups of salad vegetables, and eight glasses of water daily. They were encouraged to use avocado oil, coconut oil, olive oil, and butter.
In addition to the aforementioned guidelines, a typical keto diet includes moderate protein intake (20 to 25 percent) sourced from meat, fatty fish, eggs, nuts, and seeds.
The ketogenic (keto) diet, favored by celebrities, not only aids in weight management and diabetes control but also enhances mood and mental well-being by optimizing brain metabolism. Research indicates that by reducing carbohydrates and relying on fats for energy, the keto diet can help manage psychiatric disorders like schizophrenia and bipolar disorder. A Stanford study revealed that it reduced markers of metabolic syndrome, enhanced mental health, and delivered various physical benefits.
