Average Body Fat Percentage: What Does It Mean?

• Save

Defining an ‘average’ body fat percentage is complex due to the variability influenced by factors such as age, sex, and genetics. Healthy body fat ranges are generally 21–31% for women and 14–24% for men, with ideal percentages for good health being slightly broader at 18 to 28 percent for women and 10 to 20 percent for men.

For men, an average body fat percentage is around 20–24%, with a body fat percentage of 25% or more being considered a marker for obesity. As for women, the range is slightly higher due to physiological needs. It’s important to note that these averages are influenced by race and ethnicity, indicating that ideal body fat percentage charts may have cultural or racial biases.

Gender Differences in Body Fat Percentages

The difference in body fat percentages between genders is not merely a result of societal norms or fitness trends. Women generally require higher body fat percentages than men due to physiological needs like organ protection, hormone regulation, and childbearing. This difference is influenced by genetic, epigenetic, and hormonal factors, which impact adipose tissue distribution and its correlation with metabolic health.

During puberty, boys typically gain more lean mass, while girls increase in fat mass, leading to the development of gender-specific fat distribution patterns. Women on average have about 10% higher body fat than men for the same body mass index (BMI), a difference that persists across the lifespan. They also have a higher amount of subcutaneous adipose tissue (SAT) in both the abdominal and gluteofemoral areas compared to men.

Interestingly, women’s tendency to deposit more body fat in the hips and thighs may provide protection against metabolic diseases like type 2 diabetes and atherosclerosis.

Age-Related Variations in Body Fat Percentage

Age is another factor that affects body fat percentage. As we age, our resting metabolic rate (RMR) tends to decrease, which can result in an increase in fat mass and a decrease in muscle mass. The metabolic rate of organs and tissues, a key component of total energy expenditure, also declines with age, influencing body composition.

Adjustments to body fat percentage goals should consider age-related increases in fat mass and decreases in fat-free mass. For women, menopause is associated with a redistribution of body fat toward a more central location, due to a decrease in estrogen levels. Thus, ideal body fat percentages for health vary by age, and there are specific ranges recommended for each decade for men and women.

The Importance of Body Fat Percentage

• Save

Body fat percentage is a significant factor in determining overall health and fitness, providing a more accurate assessment of disease risk than body weight alone. It’s not about vanity or achieving a particular aesthetic; maintaining a healthy body fat percentage is about reducing the risk of chronic illnesses such as:

• heart disease
• type 2 diabetes
• gallstones
• breathing problems
• certain types of cancer

Although focusing on overall well-being is paramount, we can notably influence our health by controlling our body fat percentage through lifestyle choices.

Essential Functions of Body Fat

Fat is not an enemy. In fact, body fat is a highly concentrated source of energy, providing 9 calories per gram, which is over twice the amount of energy provided by proteins or carbohydrates. Moreover, it’s not just a storage system. Fat tissue is metabolically active, releasing fatty acids as energy when needed, and serves to insulate and protect the body’s organs.

But the role of fat goes beyond energy storage and organ protection. Dietary fats are integral structural elements of cell membranes, contributing to their fluidity and influencing various cellular functions. Certain fatty acids, such as docosahexaenoic acid (DHA), are vital for brain health, comprising a significant part of the brain’s fatty acid composition. Our bodies need fat, but the key is having the right amount.

Risks Associated with High and Low Body Fat Percentages

Although fat is vital to our body functions, having either too high or too low body fat percentages can significantly affect mortality risks. High levels of excess body fat are strongly correlated with an increased risk of cardiovascular disease, which includes:

• heart disease
• stroke
• type 2 diabetes
• certain types of cancer
• premature deaths from these diseases

The culprit here is visceral fat, which secretes inflammatory chemicals promoting insulin resistance.

On the other hand, having too little body fat can lead to insufficient essential fat for normal functions such as hormone regulation and temperature control. This imbalance can result in:

• energy deficiency
• feeling cold
• decreased stamina
• constant hunger
• increased health risks

Also, the location of body fat contributes to health risks, as abdominal fat wrapped around vital organs in the abdominal cavity can worsen metabolic problems. Thus, maintaining a balance is key.

Measuring Your Body Fat Percentage

• Save

Grasping the significance of body fat percentage is key, but accurately measuring body fat is just as important. To calculate body fat percentage, various methods can be used, including:

• Hydrostatic weighing
• DEXA scans
• Skinfold calipers
• Online calculators
• Bioelectrical impedance scales

However, the accuracy of body fat measurement may vary, with methods like DEXA scans providing more precise results, while calipers and bioelectrical impedance scales can carry a risk of inaccuracy.

One commonly used method to estimate body fat percentage is the Body Mass Index (BMI), a calculation based on weight and height. However, BMI doesn’t differentiate between muscle and fat mass. To measure body fat more accurately, skinfold calipers offer a good alternative, though they may not match the accuracy of professional methods to measure body fat percentage.

Circumference measurements taken at various points on the body in combination with formulas like the US Navy body fat calculation can serve as a practical approach to estimate body fat levels. Emerging technologies such as Spren leverage smartphone cameras and validated machine learning algorithms to offer accurate body composition analyses.

Skinfold Calipers

Skinfold calipers are used to measure the thickness of subcutaneous fat at specific locations on the body, providing a cost-effective and portable method for tracking body fat percentage. However, the accuracy of skinfold measurements depends on consistent measurement locations and the precision of the assessor using the calipers.

To correctly use skinfold calipers, one must:

• Avoid including muscle in the pinch
• Maintain a consistent technique horizontally or vertically, typically on the right side of the subject
• Use high-quality calipers
• Have the same trained professional consistently take the measurements

Reliable results from skinfold measurements are more likely when following these guidelines.

Advanced Techniques

For those seeking more precise results, advanced techniques like Dual Energy X-ray Absorptiometry (DEXA) are considered the gold standard for measuring body composition. However, such methods are more costly than other methods and their access is generally limited to certain institutions such as universities or research facilities.

Bioelectrical impedance analysis (BIA) is another advanced method that provides a more detailed body composition analysis. While BIA scales are increasingly available for home use, their accuracy can be influenced by factors such as hydration levels and recent physical activity. Thus, while advanced techniques offer greater precision, they do come with their own set of limitations and may not be necessary for the average person seeking to track their body fat percentage.

Setting Healthy Body Fat Percentage Goals

• Save

Establishing body fat percentage goals isn’t about aiming for a specific number, but rather understanding what’s best for your individual body and health condition. Healthy body fat percentages vary significantly between individuals due to factors such as:

• Genetics
• Age
• Sex
• Ethnicity

Personal body fat percentage goals should align with general health recommendations, considering one’s age and sex.

Athletes often have lower body fat percentages compared to non-athletes, which should be considered when setting goals. It’s also important to remember that striving for the lowest possible body fat percentage can be detrimental to health, just as having too high a percentage can lead to other health problems. Your ideal body fat percentage should be determined in consultation with a healthcare professional, taking into account your current health status and personal needs.

Determining Your Ideal Body Fat Percentage

For men, the healthy range of body fat percentages varies by age: 8-19% (20-39 years), 11-21% (40-59 years), and 13-24% (60-79 years).

For women, healthy body fat percentages are higher than men’s and also have a healthy range that varies by age: 21-32% (20-39 years), 23-33% (40-59 years), and 24-35% (60-79 years).

However, there is no one-size-fits-all body fat percentage. A person’s body fat percentage should be determined based on an individual’s current health status, the sport or activity they are training for, and personal standards. Achieving specific body fat percentages requires varying levels of time and dedication, and professional assessment with tools like fat calipers or underwater weighing is best for personal advice.

Women generally require more essential body fat than men due to the demands of potentially bearing children and other hormonal factors affecting fat distribution.

Strategies for Achieving Your Body Fat Percentage Goals

Achieving body fat percentage goals requires a comprehensive lifestyle approach, encompassing:

• Dietary adjustments, such as incorporating healthy fats (e.g. olive oil and nuts), reducing sugary and alcoholic beverages in favor of water or green tea, consuming high-fiber and whole-grain foods, and increasing protein intake
• Exercise routines, including a combination of cardiovascular exercises (e.g. running, swimming) and strength training exercises (e.g. weightlifting, bodyweight exercises)
• Lifestyle changes, such as getting enough sleep, managing stress levels, and staying consistent with healthy habits

By implementing these strategies, you can work towards reducing body fat and improving overall health.

Exercise is another crucial factor in reducing body fat. Here are some types of exercises that can help improve body composition and reduce body fat percentage:

• Circuit training
• Cardiovascular exercises like running or cycling
• High-intensity interval training (HIIT)
• Strength training
• Tweaking fitness habits to gain lean mass, especially after resistance training

Engaging in these exercises will help you achieve your goals.

Maintaining a Healthy Body Fat Percentage
