What slows down your metabolism?

Written by Editorial Team | Last Updated: August 2026

Several physiological, behavioral, and environmental factors can slow down your body's metabolic rate over time. Key contributors include the natural loss of muscle mass associated with aging, severe caloric restriction or crash dieting that triggers a starvation response, chronic sleep deprivation, and high stress levels that elevate cortisol. Additionally, a sedentary lifestyle lacking physical movement, inadequate daily protein intake, and certain medical conditions like hypothyroidism or hormonal imbalances can significantly depress overall energy expenditure and metabolic efficiency.
