Factors associated with overweight cats successfully completing a diet-based weight loss programme: an observational study

Table 2 Comparison of the results of weight loss amongst groups

For cats that either completed or stopped, data are expressed as median (range). Given that only two cats died, individual results are instead reported, with the same order used for results from each cat. HPHF: High protein high fibre (Royal Canin Satiety support); HPMF: High protein medium fibre (Royal Canin Obesity support). ^aAverage energy intake calculated as kcal per kg of ideal bodyweight. ^bWeight loss stalls are the number of times where the patient failed to lose weight between clinic visits. ^cDietary energy reductions are the number of times the daily energy intake had to be reduced due to slow progress. ^dActual weight lost are expressed as a percentage of starting body weight. ^eRate of weight loss was calculated as percentage of starting body weight lost per week
