An excess of body fat is one of the biggest public health concerns in the world, due to its relationship with the emergence of other health problems. Evidence suggests that supplementation with long-chain polyunsaturated fatty acids (omega-3) promotes increased lipolysis and the reduction of body mass. Likewise, this clinical trial aimed to evaluate the effects of supplementation with krill oil on waist circumference and sagittal abdominal diameter in overweight women. This pilot, balanced, double-blind, and placebo-controlled study was carried out with 26 women between 20 and 59 years old, with a body mass index >25 kg/m. The participants were divided into the control (CG) ( = 15, 3 g/daily of mineral oil) and krill oil (GK) ( = 16, 3 g/daily of krill oil) groups, and received the supplementation for eight weeks. Food intake variables were obtained using a 24 h food recall. Anthropometric measurements (body mass, body mass index, waist circumference, and sagittal abdominal diameter) and handgrip strength were obtained. After the intervention, no changes were found for the anthropometric and handgrip strength variables ( > 0.05). Regarding food intake, differences were found for carbohydrate ( = 0.040) and polyunsaturated ( = 0.006) fatty acids, with a reduction in the control group and an increase in krill oil. In conclusion, supplementation with krill oil did not reduce the waist circumference and sagittal abdominal diameter. Therefore, more long-term studies with a larger sample size are necessary to evaluate the possible benefits of krill oil supplementation in overweight women.
体脂肪过多是全世界最大的公共健康关注点之一，因为它与其他健康问题的出现有关。有证据表明，补充长链多不饱和脂肪酸（ω-3）可促进脂肪分解和体重减轻。同样，这项临床试验旨在评估补充磷虾油对超重女性腰围和矢状腹部直径的影响。这是一项前瞻性、均衡、双盲、安慰剂对照研究，共纳入 26 名年龄在 20 至 59 岁、体重指数 >25 kg/m 的超重女性。参与者被分为对照组（CG）（= 15，每日 3 克矿物油）和磷虾油组（GK）（= 16，每日 3 克磷虾油），并接受了为期八周的补充剂治疗。通过 24 小时食物回忆获得食物摄入变量。测量了人体测量学指标（体重、体重指数、腰围和矢状腹部直径）和握力。干预后，人体测量学和握力变量均未发生变化（>0.05）。关于食物摄入，碳水化合物（= 0.040）和多不饱和脂肪酸（= 0.006）存在差异，对照组减少，磷虾油组增加。总之，补充磷虾油并未减少腰围和矢状腹部直径。因此，需要更多长期、更大样本量的研究来评估磷虾油补充剂对超重女性的可能益处。
