And, yes, your basalÂ metabolicÂ rate (BMR)âthe number of calories your body needs to melt just to stay aliveâis partly genetic, which explains why some women can eat junk and stay rail thin, while others seem to just look at a pumpkin pie and gain 5 pounds.
YourÂ metabolismÂ is also influenced by plenty of other factors, however, such as your age and even your lifestyle habits like sleeping routine and snacking patterns, says Pamela Peeke, MD, author of The Hunger Fix ($12, amazon.com).
