Several canine weight loss protocols were evaluated to determine their relative safety and efficacy. Dogs were fed 100%, 75%, 60%, or 50% of maintenance energy requirements (MERs) using the dogs' target body weights. No indications of adverse health effects were observed with any weight loss protocol. Triiodothyronine (T3) levels and apparent MERs decreased in dogs restricted to 50% to 60% of their MERs. The rate of weight loss was correlated linearly with degree of calorie restriction, although there was considerable individual variation. Percent overweight by the end of the test was not different between protocol groups for dogs fed 50%, 60%, or 75% of MERs. Therefore, any of the protocols tested in this study may be used in the management of overweight dogs; however, individual responses will be expected to vary, and severe calorie restriction may predispose dogs to weight rebound.
对几种犬类减肥方案进行了评估，以确定它们的相对安全性和有效性。根据犬类的目标体重，分别按照维持能量需求（MER）的100%、75%、60%或50%来喂养犬只。在任何减肥方案中均未观察到对健康有不良影响的迹象。限制在MER的50%至60%的犬只，其三碘甲状腺原氨酸（T3）水平和表观MER均有所下降。尽管个体差异较大，但体重减轻的速率与热量限制程度呈线性相关。对于喂食MER的50%、60%或75%的犬只，各方案组在试验结束时的超重百分比并无差异。因此，本研究中测试的任何一种方案均可用于超重犬的管理；然而，预计个体反应会有所不同，且严格的热量限制可能会使犬只易于体重反弹。
