In plain English

Adults with overweight who follow a ketogenic diet for three months experience a 17.9% decrease in fatigue symptoms, with the largest reductions seen in those who started with higher fatigue levels.

See the scientific wording

In adults with overweight, a three-month ketogenic diet is associated with a 17.9% reduction in fatigue symptoms, particularly among those with higher baseline fatigue levels, suggesting a potential benefit for fatigue related to obesity.

Why this might work

When the body burns fat instead of sugar for energy, it produces ketones that turn off a key inflammation switch in immune cells. This reduces swelling and irritation throughout the body, especially in fat tissue, which directly lowers feelings of tiredness.
