The anti-obesity effects of yeast hydrolysate (YH) supplementation (1.0 g/d) have already been demonstrated. We investigated whether a low dose of YH (0.5 g/d, YH-500) also has the anti-obesity effects. Thirty obese women were randomly assigned to the control or YH-500 groups. After 8 weeks, weight and body mass index were significantly reduced by the YH treatment (0.5 g/d) (<0.05). The YH-500 group lost a significant amount of body fat after the 8-week treatment: fat mass 25.9 kg (baseline) versus 23.8 kg (8th week), <0.01; fat mass ratio 38.8% (baseline) versus 36.5% (8th week), <0.05. The YH-500 group showed a significant reduction in calorie intake during the 8-week treatment (<0.001). The control group wanted to eat much more food (<0.05) and sometimes thought about eating more often compared with the YH-500 group (<0.05). Whereas the control group showed a slightly increased sweet preference, the YH-500 group showed a significant reduction in sweet preference (<0.05). In conclusion, low dose YH supplementation (0.5 g/d) may induce a reductions in weight and body fat in obese women via the reduction of calorie intake.
补充酵母水解物（YH，1.0克/天）的抗肥胖作用已得到证实。我们研究了低剂量YH（0.5克/天，YH - 500）是否也具有抗肥胖作用。30名肥胖女性被随机分为对照组或YH - 500组。8周后，YH治疗组（0.5克/天）的体重和体重指数显著降低（<0.05）。YH - 500组在8周治疗后体脂显著减少：脂肪量从25.9千克（基线）降至23.8千克（第8周），<0.01；脂肪量比例从38.8%（基线）降至36.5%（第8周），<0.05。YH - 500组在8周治疗期间卡路里摄入量显著减少（<0.001）。与YH - 500组相比，对照组想吃更多的食物（<0.05），并且有时更频繁地想吃东西（<0.05）。对照组的甜味偏好略有增加，而YH - 500组的甜味偏好显著降低（<0.05）。总之，低剂量补充YH（0.5克/天）可能通过减少卡路里摄入量来降低肥胖女性的体重和体脂。
