Metabolic Health: A New Frontier in mental Wellbeing
Table of Contents
A growing body of research suggests a powerful link between the body’s metabolic function and mental health, challenging customary approaches focused solely on brain chemistry. For decades, the prevailing view in psychiatry centered on chemical imbalances, but experts are now exploring how efficiently the body produces and uses energy – its overall metabolic health – may be equally crucial in maintaining mental wellbeing.
The power of Nutrition: Fueling the brain
“our nutrition is the cornerstone of metabolic health and physiological function,” one expert emphasized. “Nutrition is irreplaceable.” This foundational role of diet is highlighted by the story of Michael, a former nutrition client who found relief from long-standing depression and anxiety after adopting an elimination diet. After years of unsuccessful therapies and medications, Michael, also battling an autoimmune condition, discovered that removing gluten, dairy, and sugar dramatically improved his mental state.
This discipline investigates how diet and inflammation impact the brain’s energy metabolism, ultimately influencing mood. According to Dr. Matthew Bernstein, a certified psychiatrist and leader in metabolic psychiatry, “Many important mechanisms actually have nothing to do with traditional neurotransmitters, but rather ketone bodies can bypass the brain’s insulin resistance problem, directly provide energy to brain cells, and improve mitochondrial health.”
Research indicates a meaningful overlap between severe mental illness and metabolic syndrome, with approximately one-third of individuals experiencing both. when brain cells are deprived of energy, their “power plants,” known as mitochondria, can malfunction, leading to brain inflammation and impaired mental function.
Therapeutic Ketogenesis: From Epilepsy to Depression
Recognizing the link between metabolism,brain energy,and inflammation,researchers are exploring therapeutic ketosis – initially developed to treat epilepsy – as a potential intervention for mental health conditions. A clinical trial demonstrated that improving insulin sensitivity with metformin reduced depressive symptoms in patients with treatment-resistant bipolar disorder.
Furthermore, a preliminary study published in Translational Psychiatry in september 2025 revealed that patients with severe depression experienced a roughly 70% reduction in depressive symptoms after following a carefully designed ketogenic diet for 10 to 12 weeks. It’s important to note that therapeutic ketosis differs from the popular weight-loss ketogenic diet, requiring medical supervision and precise nutrient calculations to effectively alter metabolic physiology. Dominic D’Agostino, an associate professor at the University of South Florida, explained, “If you increase ketone levels in the blood, they quickly cross the blood-brain barrier and resume normal brain metabolic activity.” Ketone bodies offer the brain an alternative energy source, reduce inflammation, and boost levels of GABA, a calming neurotransmitter.
Practical Dietary Strategies for Improved Mental Health
While strict therapeutic ketosis may be necessary for severe mental illness, a less restrictive low-carbohydrate approach can be effective for moderate depression, anxiety, or attention problems. Metabolic psychiatry clinician Erin louise Bellamy suggests that eliminating ultra-processed foods is a crucial first step toward improving metabolic health. She advocates for a return to the dietary patterns of previous generations, emphasizing:
- Prioritizing high-quality animal protein.
- Cooking with natural fats like butter or coconut oil.
- Consuming a diverse range of vegetables, particularly green leafy varieties.
Dr.Bernstein recommends a gradual approach: initially eliminating ultra-processed foods, added sugars, refined flours, and industrial vegetable oils, followed by consideration of a low-carbohydrate or low-glycemic index diet. He also noted, “The first thing is don’t be afraid of fat. There’s really no conclusive evidence that saturated fat is bad for us.” Bellamy reinforces the empowering message that individuals have agency over their health, stating, “You, as an individual, have the power to choose how you eat every day. All of this is within your control now, you don’t have to wait.”
It is indeed crucial to consult with a physician before making significant dietary changes, especially if currently taking medication for a mental health condition.
