The Claim
A 1-month very-low-calorie ketogenic diet in women with obesity is associated with a 65% reduction in carbohydrate oxidation and an 11% increase in fat oxidation, reflecting a metabolic shift toward fat utilization as the primary fuel source.
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.
In women with obesity, following a very-low-calorie ketogenic diet for one month results in a 65% decrease in the body's use of carbohydrates for energy and an 11% increase in the use of fat for energy.
See the scientific wording
A 1-month very-low-calorie ketogenic diet in women with obesity is associated with a 65% reduction in carbohydrate oxidation and an 11% increase in fat oxidation, reflecting a metabolic shift toward fat utilization as the primary fuel source.
When carbohydrate intake drops very low, the body runs out of stored sugar in the liver, so it starts breaking down fat for energy. The liver turns that fat into ketones, which the brain and muscles use instead of sugar. This stops the body from burning sugar and makes it burn fat instead.
What the research says
1 studyAfter one month on a very low-calorie keto diet, the study found that women burned 65% less carbs and 11% more fat for energy — just like the claim says. This means their bodies switched to using fat as the main fuel.
