| Popis: | Fatty acid (FA) composition is a determinant of the physiological effects of dietary oils. This study investigated the effects of vegetable oil supplementation with different FA compositions on anthropometric and biochemical parameters in obese women on a hypocaloric diet with lifestyle modifications. Seventy-five women (body mass index, BMI, 30&ndash 39.9kg/m2) were randomized based on 8-week oil supplementation into four experimental groups: the coconut oil group (CoG, n = 18), the safflower oil group (SafG, n = 19), the chia oil group (ChG, n = 19), and the soybean oil placebo group (PG, n = 19). Pre- and post-supplementation weight, anthropometric parameters, and body fat (%BF), and lean mass percentages (%LM) were evaluated, along with biochemical parameters related to lipid and glycidemic profiles. In the anthropometric evaluation, the CoG showed greater weight loss (&Delta % = &minus 8.54 ± 2.38), and reduced BMI (absolute variation, &Delta abs = &minus 2.86 ± 0.79), waist circumference (&Delta 6.61 ± 0.85), waist-to-height ratio (&Delta 0.041 ± 0.006), conicity index (&Delta 0.03 ± 0.016), and %BF (&Delta 2.78 ± 0.46), but increased %LM (&Delta abs = 2.61 ± 1.40) (p < 0.001). Moreover, the CoG showed a higher reduction in biochemical parameters of glycemia (&Delta 24.71 ± 8.13) and glycated hemoglobin (&Delta 0.86 ± 0.28) (p < 0.001). The ChG showed a higher reduction in cholesterol (&Delta 45.36 ± 0.94), low-density lipoprotein cholesterol (LDLc &Delta 42.53 ± 22.65), and triglycerides (&Delta 49.74 ± 26.3), but an increase in high-density lipoprotein cholesterol (HDLc abs = 3.73 ± 1.24, p = 0.007). Coconut oil had a more pronounced effect on abdominal adiposity and glycidic profile, whereas chia oil had a higher effect on improving the lipid profile. Indeed, supplementation with different fatty acid compositions resulted in specific responses. |
