Being healthy doesn't only mean you're at a healthy weight, it also means you have a healthy body composition without too much body fat. Having a body that's too high in body fat can put you at an increased risk for disease, including diabetes and heart disease, even if you're at a healthy weight.

In physics, density is defined as an object's mass divided by its volume. Body density is essentially your compactness, or how much you weigh for every square inch of space you take up.

Body fat percentage is a number that denotes how much of your body composition is made up of fat. The healthy range is quite different for men and women, and is often very different for bodybuilders. These athletes aim for an extremely low body fat percentage so their muscles are more defined.

The American Council on Exercise confirms that spot reduction is not a viable approach to weight loss. Losing fat around the waist and hips does not require site-specific exercises. Instead, you can focus your time and energy on any calorie-burning activity.

Starting your day with a caffeine buzz isn't likely to cause weight gain -- coffee served black is low in calories. But overdoing it can make you pack on the pounds, especially if your beverage contains added sugar and milk.

Some types of body fat -- such as the visceral fat that lies deep in your abdomen and surrounds your internal organs -- are more harmful to your health than others. Visceral fat increases your risk for certain health conditions, including breast cancer, heart disease and type 2 diabetes.
