The Claim
Twelve weeks of 12 mg daily cafestol supplementation does not improve insulin sensitivity or glucose tolerance in healthy adults with increased waist circumference, despite reducing visceral fat.
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 healthy adults with increased waist circumference, taking 12 mg of cafestol daily for 12 weeks reduces visceral fat but does not improve insulin sensitivity or glucose tolerance.
See the scientific wording
Twelve weeks of 12 mg daily cafestol supplementation does not improve insulin sensitivity or glucose tolerance in healthy adults with increased waist circumference, despite reducing visceral fat, indicating that fat loss alone may not be sufficient to enhance glucose metabolism in this population.
Cafestol lowers belly fat by changing how fat cells store oil, but this fat loss does not make the body better at using sugar or responding to insulin. The liver becomes less stressed, but this also does not improve how the body handles blood sugar.
What the research says
1 studyTaking cafestol for 12 weeks helped people lose belly fat, but their blood sugar and insulin response didn’t get better — showing that losing fat doesn’t always fix how the body handles sugar.
