Increased Energy Expenditure through Intermittent Cold Exposure Does Not Enhance Tirzepatide Induced Weight-loss in Obese Mice.

A clean null result on a reasonable hypothesis: boosting energy expenditure through cold-induced thermogenesis did not stack with tirzepatide's intake suppression. The design has strengths — both sexes, controlled diet-induced obesity — but a single mouse dose and a three-week window limit inference, and rodent cold-exposure protocols map poorly onto human behavior. Useful for tempering the 'stack cold plunges with GLP-1s' extrapolations circulating in the community.
