Sorry, ladies, this is just one of life's inequities. Men tend to have more
muscle tissue than women, and muscle tissue is what does the work that burns
calories. Women also have a genetic tendency to retain fat more efficiently
than men, since adequate stores of fat are vital during pregnancy. Women may
take some comfort in the fact that men tend to accumulate their fat deposits
around the belly, which puts them at higher risk of heart disease than
women, who tend to put on fat below the waist (hips and thighs).
