The Claim

In women with obesity, a 1-month very-low-calorie ketogenic diet is associated with significant reductions in fasting serum insulin, triglycerides, total cholesterol, and LDL cholesterol, despite concurrent loss of lean tissue.

In plain English

In women with obesity, following a very-low-calorie ketogenic diet for one month leads to measurable decreases in fasting insulin, triglycerides, total cholesterol, and LDL cholesterol, even as lean body mass is lost.

See the scientific wording

In women with obesity, a 1-month very-low-calorie ketogenic diet is associated with significant reductions in fasting serum insulin, triglycerides, total cholesterol, and LDL cholesterol, indicating improved metabolic markers despite concurrent lean tissue loss.

Why this might work

When a woman with obesity eats very few carbs and calories, her body stops using sugar for fuel and starts burning fat instead. This lowers insulin because there is no sugar to store, and the fat breakdown reduces the fat particles in the blood. At the same time, her body breaks down muscle to make glucose, which slows her metabolism. The combination of less insulin, less fat in the blood, and less muscle mass leads to lower cholesterol and triglycerides.

  1. Study: Effects of 1-Month Very-Low-Calorie Ketogenic Diet on 24-Hour Energy Metabolism and Body Composition in Women With Obesity

    After one month on a very low-calorie keto diet, obese women lost mostly fat and started burning fat for energy instead of carbs — which usually means better blood sugar and cholesterol levels, even though they also lost a little muscle.
