The Claim

In healthy lean and overweight adults, acute consumption of inulin or resistant starch results in equivalent postprandial serum short-chain fatty acid responses regardless of body weight status.

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.

Description
1 study reviewed
In plain English

When healthy lean and overweight people eat inulin or resistant starch in a single meal, their blood levels of short-chain fatty acids rise by the same amount afterward.

See the scientific wording

In healthy lean and overweight adults, acute consumption of inulin or resistant starch does not produce different postprandial serum short-chain fatty acid responses between lean and overweight individuals, challenging the hypothesis that obesity is associated with increased colonic SCFA production.

Why this might work

When inulin or resistant starch reaches the colon, gut bacteria break them down into short-chain fatty acids, which enter the bloodstream. This happens at the same rate and amount in lean and overweight people, so body weight does not change how much these fatty acids are made or absorbed.

    When lean and overweight people ate the same fiber supplements, their blood levels of short-chain fatty acids went up in similar ways—so being overweight doesn’t seem to make your gut produce more of these compounds from fiber.
