Immunometabolic parameters in overweight dogs during weight loss with or without an exercise program

Area of Science:

• Veterinary Medicine
• Canine Health
• Metabolic Research

Background:

• The impact of physical activity on metabolic health in overweight dogs remains unclear.
• Overweight dogs exhibit altered immunometabolic profiles, including inflammation and dyslipidemia.
• Understanding these factors is crucial for improving canine well-being.

Purpose of the Study:

• To investigate the influence of combined caloric restriction and a training program versus caloric restriction alone on immunometabolic health in overweight dogs.
• To evaluate changes in biomarkers related to insulin resistance, inflammation, and dyslipidemia.
• To assess the role of physical activity in conjunction with weight loss.

Main Methods:

• A 12-week intervention study involving client-owned overweight dogs (n=16).
• Two groups: fitness and diet (FD) with training, and diet-only (DO) with caloric restriction.
• Physical activity monitored by accelerometry; blood samples analyzed for insulin, C-peptide, leptin, adiponectin, CRP, MCP-1, IL-8, and cholesterol.

Main Results:

• Both groups achieved similar weight loss; accelerometer counts indicated significant physical activity.
• No significant differences in blood parameters were observed between the FD and DO groups.
• Within-group analysis showed decreased leptin in both groups; FD group had reductions in IL-8, MCP-1, and CRP, while DO group showed decreased C-peptide and HOMA.

Conclusions:

• Weight loss, achieved through caloric restriction, led to modest improvements in immunometabolic health markers in overweight dogs.
• The level of physical activity implemented in this study did not provide additional significant benefits beyond those of weight loss alone.
• Further research may be needed to determine optimal physical activity protocols for canine metabolic health.
