What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults with overweight who follow a ketogenic diet for three months show a 35.6% increase in vitality and a 21.3% improvement in mental health scores on the SF-36 questionnaire.
See the scientific wording
A three-month ketogenic diet in adults with overweight is associated with a 35.6% increase in vitality and a 21.3% improvement in mental health, as measured by the SF-36, suggesting potential benefits for energy levels and psychological well-being.
When someone eats very few carbs and more fat, the body switches to burning fat for fuel and makes ketones. These ketones give the brain and muscles a cleaner, more stable energy source than sugar. At the same time, ketones block a key inflammation system in the body, which reduces swelling and fatigue. With more energy and less inflammation, people feel more alert, less tired, and mentally clearer.
