The Claim
In adults with upper-body obesity and/or type 2 diabetes, overnight niacin infusion significantly reduces fasting phosphorylation of perilipin 1 at serine 552 compared to saline infusion.
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 upper-body obesity or type 2 diabetes, an overnight infusion of niacin lowers the phosphorylation level of perilipin 1 at serine 552 compared to an infusion of saline.
See the scientific wording
In adults with upper-body obesity and/or type 2 diabetes, fasting phosphorylation of perilipin 1 at serine 552 is significantly lower after overnight niacin infusion compared to saline, suggesting niacin’s antilipolytic effect may involve modulation of this key lipolysis-regulating protein.
Niacin binds to a receptor on fat cells, which triggers a signal that lowers the activity of a protein called perilipin 1 by removing a phosphate group from a specific spot on it. This change stops perilipin 1 from allowing fat breakdown to happen, so less fat is released from fat cells into the blood.
What the research says
1 studyStudy: Adipose Tissue Resistance to the Antilipolytic Effect of Insulin and Niacin in Humans With Obesity.
In people with obesity or type 2 diabetes, niacin lowered a specific signal in fat cells that tells them to break down fat — which helps explain why niacin reduces fat release. This matches what the claim says.
