Research paper thumbnail of A High-Protein, High-Fiber Diet Designed for Weight Loss Improves Satiety in Dogs

A diet formulated to contain a high content of both protein and fiber is more satiating than diets that contain only high fiber or high protein. Six entire female adult dogs (2 Shetland Sheepdogs, 2 Brittany Spaniels, 2 Labrador Retrievers) participated in the satiety studies; 105 adult female dogs of various breeds and ages were used for the palatability studies. Three diets (high protein [103 g/1,000 kcal] high fiber [60 g/1,000 kcal] [HPHF]; high protein [104 g/1,000 kcal] moderate fiber [35 g/1,000 kcal] [HP]; moderate protein [86 g/1,000 kcal] high fiber [87 g/1,000 kcal] [HF]) were tested. Voluntary food intake was measured in 5 sequential crossover studies, and palatability was assessed with food preference tests. Protein digestibility was significantly lower for HF (mean +/- SD; 77.7% +/- 2.52%) than for both HPHF (81.1% +/- 0.96%) and HP (81.1% +/- 1.65%) (P < .001). Short-term food intake (food ingested when offered for 15 minutes every hour for 4 hours) was lower for HPHF than for both HP and HF (P = .038). Medium-term intake (food ingested when offered 3 hours after first meal) was lower for both HPHF (27 +/- 22.2 kcal/kg(0.73)) and HF (41 +/- 6.8 kcal/kg(0.73)) than for HP (57 +/- 18.8 kcal/kg(0.73)) (P = .041). Voluntary food intake 3 hours after feeding a restricted meal (25% daily maintenance energy requirements) was significantly lower on the HPHF diet than on either the HP (-51%, P = .0051) or HF (-47%, P = .014) diets. However, there was no significant difference between the energy intake on the HP and HF diets (7%, P = .37). The HPHF and HP diets had equivalent palatability, and both were more palatable than the HF diet (P < .001). The HPHF diet had a satiating effect as evidenced by reduced voluntary intake compared with HP and HF diets, and has the potential to lead to greater compliance in weight-loss programs.

Three dietary strategies were evaluated: strategy A used a novel dry high fibre ration; strategy B used ready-prepared portions of dry and moist food; strategy C used an existing commercial dry high fibre ration fed with a measuring cup. Cats were assessed at weeks 4, 12 and 20, and adjustments to the energy allocation made if required. Mean weight loss at 20 weeks (A: 11.0 AE 1.3%, B: 10.9 AE 1.2%, C: 11.9 AE 1.7%) and mean energy allocation (A: 31.0, B: 28.5 and C: 32.2 kcal/kg of target body weight/day) were similar amongst strategies. However, owners' subjective hunger score was significantly (P < 0.001) higher with strategy C than with strategies A and B. Further, owner satisfaction was lowest with strategy C, and more owners also regarded food allowance as insufficient with this strategy. Novel diets and feeding strategies may improve outcome in feline weight loss programmes.
