The Claim
In adults with overweight, a three-month eucaloric ketogenic diet is associated with a 14.3% reduction in fat mass and a 14.7% reduction in visceral fat, while preserving muscle and bone mass.
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 adults with overweight, following a three-month eucaloric ketogenic diet results in a 14.3% decrease in fat mass and a 14.7% decrease in visceral fat, with no loss of muscle or bone mass.
See the scientific wording
In adults with overweight, a three-month eucaloric ketogenic diet is associated with a 14.3% reduction in fat mass and a 14.7% reduction in visceral fat, while preserving muscle and bone mass, suggesting it may be an effective strategy for targeted fat loss without lean tissue loss.
When carbs are very low, the liver starts making ketones from fat, and the body switches from burning sugar to burning fat for energy. Insulin drops, which lets fat cells release stored fat into the blood. The ketones then fuel the brain and muscles, so the body doesn't break down muscle or bone. Fat loss happens mostly in the belly because that fat is more sensitive to low insulin. The ketones also calm down body-wide inflammation, which helps reduce fluid retention and makes fat loss more visible.
What the research says
1 studyStudy: The impact of a ketogenic diet on weight loss, metabolism, body composition and quality of life
This study found that adults with extra weight who ate a low-carb, high-fat diet without cutting calories lost a lot of body fat and belly fat, but kept their muscle and bone — just like the claim says.
