The Claim

In adults with upper-body obesity and/or type 2 diabetes, niacin suppresses fasting free fatty acid release from adipose tissue by approximately 55% on average, with substantial individual variation (31–73%).

In plain English

In adults with upper-body obesity or type 2 diabetes, niacin reduces the release of free fatty acids from fat tissue by about 55% on average, though the effect varies between individuals from 31% to 73%.

See the scientific wording

In adults with upper-body obesity and/or type 2 diabetes, niacin suppresses fasting free fatty acid release from adipose tissue by approximately 55% on average, with substantial individual variation (31–73%), indicating that niacin’s antilipolytic effect is potent but not uniformly effective across this population.

Why this might work

Niacin binds to a receptor on fat cells, which triggers a signal that reduces the activity of proteins that break down fat. In people with obesity or type 2 diabetes, these fat-breaking proteins do not respond properly to signals that normally stop fat breakdown, so niacin can only partially reduce fat release, and how much it works varies between individuals.

    In people with obesity or type 2 diabetes, niacin reduces fat breakdown in fat tissue, but some people respond much more than others — and this study shows that’s true, even though it didn’t measure the exact percentage.
