Actually â€" once you get your head around a new eating pattern, math and science are working in your favor. It is mathematically easier to lose than to gain. For example, if you eat 3,500 calories more than you burn, you will gain 0.3 pounds (0.14 kg), but if you burn 3,500 calories more than you eat, you will lose 1 pound (0.45 kg). Also, if you want to lose weight, you can expose yourself to significant changes in temperature which speeds up your metabolism. Finally, the above information is based on a pure fat diet â€" variations to the math occur when you introduce other types of food. -- http://listverse.com/

...and just as harder to increase one's physical activity.
