There is some evidence in the literature that emphasising fish consumption may assist with weight loss. The aim was to assess the effects of advice to consume 2 fish meals per week in a weight loss diet.
A parallel randomised placebo-controlled trial was conducted in 118 obese Australian adults (mean BMI ± SD 31.3 ± 3.5 kg/m2; mean age ± SD 45 ± 10 y; 28% male). Participants received low calorie dietary advice+placebo (1 g olive oil; CONTROL), low calorie dietary advice emphasising fish+placebo (Fish), or low calorie dietary advice emphasising fish diet + LCn3PUFA supplements (Fish+S). Individualised advice targeted 2 MJ energy deficit (30%E fat, 45%E carbohydrate and 25%E protein) with or without two servings (180 g) fatty fish/wk.
All groups lost weight at 12 months (CONTROL -4.5 kg vs. Fish -4.3 kg vs. Fish+S -3.3 kg; p<0.001) and percentage body fat (
-1.5% vs. Fish: -1.4% vs. Fish+S: -0.7%; p<0.001) but there were no significant differences between groups. Cardiovascular disease risk factors changed as expected from weight loss.
Advice to consume 2 fish meals per week did not enhance the effects on weight loss of a healthy low calorie diet.

文献中有一些证据表明，强调食用鱼类可能有助于减肥。本研究旨在评估在减肥饮食中每周食用 2 餐鱼的建议的效果。
在 118 名肥胖的澳大利亚成年人（平均 BMI ± SD 31.3 ± 3.5 kg/m2；平均年龄 ± SD 45 ± 10 岁；28%为男性）中进行了一项平行随机安慰剂对照试验。参与者接受低热量饮食建议+安慰剂（1 克橄榄油；对照组）、强调食用鱼类的低热量饮食建议+安慰剂（Fish 组）或强调食用鱼类饮食+LCn3PUFA 补充剂的低热量饮食建议（Fish+S 组）。个体化建议的目标是能量亏空 2MJ（脂肪 30%E、碳水化合物 45%E 和蛋白质 25%E），同时每周食用 2 份（180 克）高脂肪鱼类。
所有组在 12 个月时均减轻体重（对照组-4.5 公斤 vs. Fish 组-4.3 公斤 vs. Fish+S 组-3.3 公斤；p<0.001）和体脂肪百分比（对照组：-1.5% vs. Fish 组：-1.4% vs. Fish+S 组：-0.7%；p<0.001），但组间无显著差异。心血管疾病风险因素的变化与体重减轻相符。
每周食用 2 餐鱼的建议并不能增强健康低热量饮食对减肥的效果。
