Men Lose More Weight Than Women on Ketogenic Diet, Study Finds
A study published in Frontiers in Nutrition has revealed that men lost nearly 12% of body weight on a ketogenic diet over 45 days, compared to about 9% in women, potentially due to differences in fat distribution, hormones, and energy metabolism.
As economies expand, the number of people living with obesity has surged worldwide. Obesity and diabetes now stand out as major global health challenges demanding urgent, collective action. Traditional dietary interventions, especially low-fat, high-carbohydrate diets, have often shown limited success, particularly among those with insulin resistance. In contrast, the ketogenic diet – which is high in fat, very low in carbohydrates, and moderate in protein – aims to shift the body into ketosis, a state where it relies on ketone bodies rather than glucose for energy.
Research has shown the ketogenic diet helps people lose weight more quickly and effectively compared to high-carbohydrate diets, without increasing short-term cardiovascular risk. Beyond shedding weight, it also improves insulin sensitivity and helps manage blood sugar in people with type 2 diabetes. However, its effects are not the same for everyone. Studies reveal men often lose more weight and body fat on the ketogenic diet than women.
