Taste preferences for sensory stimuli composed of sugar and fat are predictive of some food preferences and may help distinguish between potential subtypes of human obesity. A sample of 37 obese females was divided into high-flux and low-flux groups according to the magnitude of fluctuations in body weight. Variability in body weight is thought to be indicative of the weight cycling syndrome. The subjects tasted and rated five sucrose solutions in water and nine ice creams of varying sugar and fat content. Perceptions and preferences for sweet solutions were the same for both groups. In contrast, the high-flux group showed higher preferences for ice cream stimuli than did the low-flux group. High-flux females also rated sweet desserts higher on a food preference questionnaire than did low-flux females. Prior consumption of milkshake pre-loads did not affect preference ratings for sweet solutions. However, hedonic preferences for ice creams after pre-load consumption were reduced in the high-flux group. The weight cycling syndrome may be associated with elevated hedonic preferences for sweet and high fat foods.
对由糖和脂肪组成的感官刺激的味觉偏好可预测某些食物偏好，并可能有助于区分人类肥胖的潜在亚型。根据体重波动幅度，将37名肥胖女性样本分为高通量组和低通量组。体重变化被认为是体重循环综合征的指标。受试者品尝并评价了五种水中的蔗糖溶液以及九种不同糖和脂肪含量的冰淇淋。两组对甜味溶液的感知和偏好相同。相比之下，高通量组对冰淇淋刺激的偏好高于低通量组。在食物偏好问卷中，高通量女性对甜点心的评分也高于低通量女性。预先食用奶昔预负荷不会影响对甜味溶液的偏好评分。然而，高通量组在预负荷食用后对冰淇淋的享乐偏好降低。体重循环综合征可能与对甜食和高脂肪食物的享乐偏好升高有关。
