The Claim

Baseline body mass index (BMI) is inversely associated with the reduction in colonic prostaglandin-E2 following 12 weeks of omega-3 fatty acid supplementation, with higher baseline BMI predicting smaller reductions in prostaglandin-E2 and accounting for 16.1% of inter-individual variability in response.

Source: Higher baseline expression of the PTGS2 gene and greater decreases in total colonic fatty acid content predict greater decreases in colonic prostaglandin-E2 concentrations after dietary supplementation with ω-3 fatty acids

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 plain English

People with higher body mass index before starting omega-3 supplementation experience smaller reductions in colonic prostaglandin-E2 levels after 12 weeks, and baseline BMI explains 16.1% of the differences in response between individuals.

See the scientific wording

Baseline body mass index (BMI) is inversely associated with the reduction in colonic prostaglandin-E2 after 12 weeks of omega-3 fatty acid supplementation, with higher BMI predicting smaller PGE2 decreases and accounting for 16.1% of inter-individual variability in response.

Why this might work

In people with higher body weight, the colon has more of the enzyme that makes inflammatory molecules, but omega-3 fats from supplements do not reduce this enzyme's activity as much because there is less replacement of the fuel it needs and fewer removals of substances that keep the enzyme turned on. As a result, the inflammatory molecule PGE2 stays higher in people with higher body weight.

    People with higher body weight tend to get less anti-inflammatory benefit from omega-3 supplements in their colon, and this study proves it by showing that BMI explains about 16% of why some people respond better than others.
