Four subjects in a recent trial of eight weeks dieting with the 405 kcal/day, 42 g protein formula (Cambridge diet extra), had participated 18 months previously in an 8-week trial using the 330 kcal/day Cambridge diet formula. This permitted a quantitative comparison of two similar dieting episodes, but following substantial weight loss and variable weight regain after a successful experience with a very low calorie diet. Within the reasonable bounds of comparison between outpatient dieting experiences, there was no suggestion of impairment in ability to lose weight in subsequent dieting after weight loss on a VLCD. The experience of these subjects would not support the contention that lasting metabolic debilitation had occurred that could be attributed to repeated dieting experiences with VLCD.
在最近一项为期八周、采用每天405千卡、42克蛋白质配方（剑桥加强型饮食）节食的试验中，有四名受试者在18个月前参加了一项为期8周、使用每天330千卡剑桥饮食配方的试验。这使得对两次相似节食过程进行定量比较成为可能，不过是在经历了极低热量饮食成功减重且体重反弹情况各异之后。在门诊节食经历的合理比较范围内，没有迹象表明在极低热量饮食减重后进行后续节食时减肥能力受损。这些受试者的经历并不支持这样的观点，即发生了持久的代谢衰弱，且可归因于多次极低热量饮食的节食经历。
