<p>Breaking down the science of metabolism: Where calories go to party, but some dont get invited back. Did you know that the average metabolic rate for men is like a hungry teenager at a buffet, hovering around 2,500 calories per day, while womens metabolism hums along at a cool 2,000 calories per day? From the mysterious ways of basal metabolic rate (BMR) to the influence of genetics, environmental factors, and even that post-meal energy boost, get ready to dive deep into the wild world of energy expenditure. So grab a snack (bonus points if its metabolism-boosting!), and lets decode why some bodies burn, baby, burn, while others might need a little coaxing.</p>

Environmental impact on metabolic rate
