Warm temperatures curb appetite but can still promote weight gain, animal experiments find
Researchers at Pennington Biomedical Research Center have identified a key brain mechanism that connects environmental temperature with appetite and energy balance, offering new insight into how external conditions can shape body weight over time.
Researchers at Pennington Biomedical Research Center have discovered that warm temperatures affect appetite and weight by activating specific brain cells. Published in Communications Biology, the study reveals how these brain cells reduce food intake but also decrease the body's energy expenditure, potentially leading to weight gain over time.
The findings challenge the notion that weight regulation is solely influenced by diet and physical activity, emphasizing the role of environmental factors like temperature. Lead author Laura Kaiser, a Ph.D. student, explains that this research provides a more comprehensive understanding of how the brain integrates external cues with metabolic signals to control body weight.
Understanding these brain pathways could lead to new approaches for treating obesity, especially in environments with controlled temperatures.
