You may be able to make your breasts smaller with exercise, if you burn more calories than you consume each day. This is because the breasts are partially made up of fatty tissue. You can't target your breasts for weight loss, though, as it is impossible to spot-reduce fat.

Weight loss is helpful for lowering your disease risk, but if you go about it the wrong way, you may end up with a higher body fat percentage than when you started.

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.

Although a scale is a useful tool in measuring weight loss, it is limited to evaluating only one component: weight. When it comes to health risks related to being overweight, fat is the culprit. Measuring body fat percentage is a better indicator of how well your diet and exercise program is working.

The standard for determining what is a man’s ideal weight has changed in recent years from insurance companies’ Weight-for-Height tables to Body Mass Index (BMI) tables that correlate height and weight with BMI.

At one time or another you probably ate way more than you intended to eat. One day of binge eating may add a pound or two, but it's temporary water weight, not fat. Continuously eating more calories than your body needs -- day after day -- is what causes fat gain.

Having an apple shaped body, you might think that attention need only be paid to the areas where fat has accumulated, while ignoring the worry-free zones.

Weight-to-height ratio tables show you exactly what range your weight should be for your height, so you can easily see if you are overweight, underweight or healthy.

The body mass index uses your height and weight to estimate the level of fatness in your body. For much of the population, it's a fair enough gauge as well as simple to apply and noninvasive to perform. A BMI higher than 25 indicates that you're overweight, and when it's over 30, it indicates obesity.

Avocados are rich in a number of nutrients, particularly vitamins, fatty acids and compounds called plant sterols. The plant sterols in avocados have an effect on hormones, especially estrogen and progesterone, which are both responsible for regulating ovulation and menstrual cycles.

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. Knowing your total body density can be helpful if you plan to use it in equations that help you estimate percent body fat.

Your body burns calories every minute of every day, whether you're asleep, watching television, working at the computer or working out.
