The Claim

In adults with obesity and prediabetes, caloric restriction reduces visceral fat by 9.5% over 14 weeks, liraglutide reduces visceral fat by 4.8% over the same period, and both interventions produce significantly greater reductions in visceral fat than sitagliptin, indicating that visceral fat reduction is more responsive to energy deficit than to GLP-1 receptor activation alone.

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.

Cause and effect
1 study reviewed
In plain English

In adults with obesity and prediabetes, cutting calories reduces visceral fat more than taking liraglutide, and both reduce it more than taking sitagliptin. The amount of fat lost is directly tied to how much energy intake is reduced, not just to activating GLP-1 receptors.

See the scientific wording

In adults with obesity and prediabetes, caloric restriction reduces visceral fat by 9.5% over 14 weeks, while liraglutide reduces it by 4.8%, and both are significantly greater than the minimal change seen with sitagliptin, suggesting visceral fat reduction is more responsive to energy deficit than GLP-1 receptor activation alone.

Why this might work

When the body uses more energy than it gets from food, it breaks down stored fat, especially from the belly area, to fuel itself. This process is stronger when food intake is cut significantly, and it happens even if appetite hormones are changed without reducing calories.

    Cutting calories burned more belly fat than taking the drug liraglutide, and the other drug (sitagliptin) didn’t help at all — proving eating less works better than just changing appetite hormones.
