Effect of dietary fish oil on body fat mass and basal fat oxidation in healthy adults
Abstract
Objective To investigate whether the substitution of fish oil for visible fats in a control diet (52% carbohydrates, 16% protein, 32% fat; P:S 0.2) influences body fat mass and substrate oxidation in healthy adults.Design Six volunteers (5 men; 23 +/- 2 y; BMI: 21.9 +/- 1.6) were fed a control diet (C) ad libitum during a period of three weeks and, 10-12 weeks later, the same diet where 6 g/d of visible fat were replaced by 6 g/d of fish oil (FO) for another three weeks.Results Energy intakes (IKA-calorimeter) were unchanged. Body fat mass (Dual-energy X-ray absorptiometry) decreased with FO (-0.88 +/- 0.16 vs -0.3 +/- 0.34 kg; FO vs C; P < 0.05). When adjusted for lean body mass (Ancova), resting metabolic rate (indirect calorimetry) was unchanged. Basal respiratory quotient decreased with FO (0.815 +/- 0.02 vs 0.834 +/- 0.02; P < 0.05) and basal lipid oxidation increased with FO (1.06 +/- 0.17 vs 0.87 +/- 0.13 mg kg(-1) min(-1); P < 0.05).Conclusion Dietary FO reduces body fat mass and stimulates lipid oxidation in healthy adults.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“Clinical studies have shown that OM3FA treatment increases fatty acid oxidation, as determined by indirect calorimetry [35, 36].”
In the citing paper
“rather, increased hepatic fatty acid oxidation is likely.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
