The Claim

In individuals with upper-body obesity and/or type 2 diabetes, niacin infusion reduces phosphorylation of Akt at Ser473 and perilipin 1 at Ser552 in adipose tissue compared to saline infusion, indicating impaired signaling at key regulatory nodes of lipolysis suppression.

How it works
1 study reviewed
In plain English

In people with upper-body obesity or type 2 diabetes, niacin infusion decreases the activation of Akt at Ser473 and perilipin 1 at Ser552 in fat tissue compared to saline infusion, which reflects reduced signaling at critical points that normally suppress fat breakdown.

See the scientific wording

In individuals with upper-body obesity and/or type 2 diabetes, niacin infusion reduces phosphorylation of Akt at Ser473 and perilipin 1 at Ser552 in adipose tissue compared to saline infusion, indicating impaired signaling at key regulatory nodes of lipolysis suppression.

Why this might work

Niacin binds to a receptor on fat cells, which triggers a signaling pathway that reduces the activation of two key proteins, Akt and perilipin 1, that normally stop fat breakdown. When these proteins are less active, fat cells continue releasing fatty acids even when the body tries to stop them, leading to higher levels of fat in the blood.

  1. Study: Adipose Tissue Resistance to the Antilipolytic Effect of Insulin and Niacin in Humans With Obesity.

    In people with obesity or type 2 diabetes, niacin made two key fat-control proteins less active in fat tissue, just like the claim said. Even though niacin still stopped fat breakdown, it did so by affecting different parts of the system than expected.
