Fat plays an important role in good health—it’s the body’s way of storing energy to support your metabolism. Overall, there are two different types of body fat, and it’s important to know the difference. They include:
Essential fat is located in your nerves, brain, bone marrow and in the membranes that protect the organs. Composed of fatty acids, essential fat plays a significant role in health, because it provides energy reserves and protects the internal organs.
Storage fat is found around the organs and under the skin. It also provides protection and acts as an insulator to keep the body warm.
"The factors determining fat mass in adult humans are not fully understood, but increased lipid storage in already developed fat cells (adipocytes) is thought to be most important."
As shown in the diagram above, adipocytes consist of a nucleus and a fat reservoir.
If you consume more calories than you burn, fat cells will grow and multiply—and if you lose weight, the body burns fat inside the fat cells.
Types of body fat
Generally, there are two different types of body fat: essential fat (fat that ensures the proper functioning of your body), and storage fat (fat that protects your organs from shock and trauma). Broken down even further, fat can be categorized as follows:
White fat is stored under the skin and around the organs, and is the body’s way of storing energy for later use. It also releases hormones. High amounts of white fat can increase your risk of diabetes, stroke, and disease.
Brown fat is sometimes called “good” fat. It helps to produce body heat to keep you warm in cold conditions. Interestingly, human newborns and hibernating mammals have high levels of it, and lean people tend to have more of it than overweight people. When it is stimulated, it can burn calories.
Beige fat is a relatively new—and really interesting—category of fat cells. Beige fat cells are located near the collarbone and along the spine. They actually burn calories, so researchers are looking at how they might be used in new therapies for diabetes and obesity.
Subcutaneous fat lies just under the skin. It may be harmless and even protect against some diseases, but if it’s over the belly, it may contribute to health problems.
First, it’s important to know that healthy body-fat levels are different for men and women. The American Council on Exercise (ACE), which provides a body fat calculator based on skinfold measurement, says there are many factors that play into the right number for you.
Thus, body fat percentage results are usually sorted by age and sex according to the following categories.
Underfat |Healthy |Overfat |Obese
Body fat ranges for females
Female bodies need more fat to maintain a good hormonal balance, as well as healthy and regular menstrual cycles. Females tend to have 6-11% more body fat than males.
Body fat ranges for males
For males age 20 to 39, having a body fat percentage that is above 25% is considered obese. This means that no more than a quarter of your total body weight should consist of fat.
How can you measure body fat?
There are many ways to determine your body fat percentage. As you age and your lean muscle progressively decreases, it is important to keep these numbers in mind.
Body fat percentage is not the same as Body Mass Index (BMI), which is often used as an indicator of your overall health based on your height and weight and doesn’t take your total body composition into account.
In this study, 8% of all men and 7% of all women were incorrectly classified as obese using standard BMI cutoff points.
Some smart scales now offer a set of features that include the measurement of your full body composition via bioelectrical impedance analysis.
What is the difference between lean body mass and body fat?
Lean body mass includes your bones, muscles, organs, and tissues, which all contain some essential fat. Having a high percentage of lean fat mass can boost your metabolism. Body fat percentage, however, includes your total body fat, and too much of it—especially visceral fat—can be dangerous.
Diets don’t work, but they’re really popular. Unfortunately, no matter what diet they chose, people gained back 65% of the weight they lost—and the regained weight was mostly fat.
Healthy eating habits are really powerful. We found that those who ate four or more fruits and vegetables a day, consumed fewer than 2 dairy products a day, and ate meals that were cooked using fresh products were less likely to be overweight. Those who skipped meals, ordered takeout, ate red meat 3 or more times a week, and ate while doing other activities (such as working or watching TV) were more likely to be overweight.
Tracking your weight regularly. We found that when overweight or obese users track their weight and food intake regularly, they lose over 7 times more weight than users who are not regular trackers. We also found that people who weighed themselves more tended to be more active. Why? One theory: A daily weight reminder can help to remind you of your weight goals and healthy behaviors.
Get some sleep. Our data shows that better sleep may impact your weight. In a study, we found that an astounding 66.5% of users who slept an average of less than 7 hours a night were overweight. We also found that people who slept 7–8 hours a night were the least likely to be sedentary.
