Whether you workout before or after breakfast makes little difference for casual exercise. When training, there may be a benefit to fasting before exercise.

If you're over 60, here are some important things to be aware of to ensure that you enjoy greater health and quality of life.

In her latest book Metabolism Revolution, Haylie Pomroy makes the case for how certain factors can make it easier for your body to hold onto excess fat. Here's how to fix that.

Raising your metabolism is tricky. Cardio workouts elevate it for a short period of time, but it doesn't have a lasting effect.

New research maintains that the way you smell food may determine how your body metabolizes it, meaning simply smelling food can make you gain more weight.

Your metabolic rate relates to the energy your body uses in a day, measured in units of energy called calories. When you're managing your weight, a faster metabolism means you can take in more calories from food and drink without gaining weight.

While a lightning-fast metabolism can make it easier to lose weight, it won't necessarily make you healthier. The advantage of burning a lot of energy and easy weight control may have a trade-off in terms of life expectancy.

Losing up to 22 pounds in 13 days certainly sounds like a winning diet if you want to lose weight fast. However, the 13 Day Metabolism diet is a fad diet with strict rules and severe calorie restriction that you may have a hard time following for the allotted days.

The term "metabolism" refers to the chemical reactions that take place in your body each day, and the energy -- in the form of calories -- that's burned carrying out those reactions.

The body requires energy to sustain itself and perform all the functions of daily life. The process of converting nutrients from food into energy is called cellular respiration. The energy from this biochemical process is captured in a chemical called adenosine triphosphate (ATP).
