The ketogenic diet , often called the keto diet, is one that is very high in fat, very low in carbohydrates, and low to moderate in protein. It typically supplies 75 to 90 percent of calories from fat, versus a more usual intake of 20 to 35 percent. It is intended to force the body to burn fat for energy rather than glucose—a state known as ketosis. Though many use the diet in order to accelerate
Why Does Ketogenic Diet Develop?
Understanding what causes ketogenic diet is essential for prevention and treatment. Research consistently shows that ketogenic diet arises from a complex interplay of biological, psychological, and social factors — rarely from a single cause.
What Researchers Have Found
Research into ketogenic diet has identified multiple contributing pathways. Studies using neuroimaging, genetics, and longitudinal data reveal that no single factor fully explains why ketogenic diet develops.
Biological Factors
Biological contributors to ketogenic diet include:
- Genetics: Family history increases risk; certain genes influence vulnerability
- Brain chemistry: Neurotransmitter imbalances (serotonin, dopamine, norepinephrine) play key roles
- Brain structure: Differences in the prefrontal cortex, amygdala, and hippocampus are documented
- Physical health: Chronic illness, hormonal changes, and sleep disruption can trigger or worsen ketogenic diet
Neurological Basis
Glucose is the brain’s preferred source of fuel because it’s fast. But glucose is inefficient; it doesn’t burn clean. Debris accumulates in the mitochondria , the fuel furnaces of cells. And glucose generates free radicals of oxygen, which progressively damage cells. Oxidative stress also leads to the buildup of toxic proteins that are the hallmark of Alzheimer’s disease. Over time, the processes that power brain cells lose efficiency, setting the stage for cognitive decline . The same processes may contribute to other psychiatric disorders, such as depression . During periods of ketosis, by c
Psychological Factors
- Early experiences: Childhood adversity, attachment disruption, and trauma shape psychological vulnerability
- Cognitive patterns: Negative thinking styles, perfectionism, and rumination increase risk
- Coping skills: Limited emotional regulation skills make ketogenic diet more likely under stress
- Personality: Certain traits (neuroticism, harm avoidance) are associated with higher risk
Social and Environmental Factors
Environmental factors — including chronic stress, relationship problems, financial difficulty, and major life events — can trigger ketogenic diet in vulnerable individuals.
What Triggers an Episode?
Even in people with predisposing factors, ketogenic diet often requires a triggering event:
- Major life transitions (job loss, relationship breakdown, bereavement)
- Prolonged stress without adequate recovery
- Substance use or withdrawal
- Physical illness or injury
- Social isolation or conflict
Protective Factors
Not everyone with risk factors develops ketogenic diet. Protective factors include: strong social support, effective coping skills, physical health maintenance, access to care, and psychological resilience built through prior challenges.
