The Claim

Under euglycemic conditions, when insulin and niacin suppress lipolysis to equivalent levels in healthy adults with normal body weight, insulin does not increase the rate of free fatty acid storage in subcutaneous adipose tissue more than niacin.

How it works
1 study reviewed
In plain English

When insulin and niacin reduce fat breakdown to the same degree in healthy individuals, neither causes a greater increase in fat storage under the skin than the other, suggesting that insulin does not uniquely promote fat storage beyond what is expected from reduced fat breakdown.

See the scientific wording

In healthy adults with normal body weight, insulin does not increase the rate of free fatty acid storage in subcutaneous adipose tissue more than niacin when both agents suppress lipolysis to equivalent levels, suggesting that insulin's effect on fatty acid uptake is not distinct from general lipolysis suppression under euglycemic conditions.

Why this might work

When fat cells stop releasing fatty acids into the blood, there are fewer fatty acids floating around for them to take back in and store. Whether this stoppage is caused by insulin or niacin, the result is the same: less fatty acid available to be stored, so storage rates don’t change based on which drug is used.

    When insulin and niacin both lower fat release from fat cells to the same level, they also cause the same amount of fat to be stored back in fat tissue—meaning insulin doesn’t make fat cells store more fat just because it’s insulin.
