A Layman’s Guide to Body Fat Percentage

Body fat percentage may awfully sound scientific, but it’s really about understanding our health in a simple, meaningful way.

This measurement offers a clearer understanding of our health, beyond just the numbers we see on a scale.

We’ll see here why the DNA weight loss program is an important health indicator for you.

What is Body Fat Percentage?

While ‘body fat percentage’ might sound technical, it’s really a simple idea that plays a big role in how we understand our health.

Unlike the numbers we see on a weighing scale, which don’t differentiate between what’s fat, muscle or bone, body fat percentage gives us a clearer picture of our body’s actual composition.

Basically, body fat percentage is a measure of the amount of fat in your body in relation to your total body weight. This includes both essential body fat, which is necessary for your body to function properly, and storage fat, which your body reserves for energy.

Why Should it Matter to You?

Knowing your body fat percentage helps in understanding whether the weight you’re carrying is healthy for you.

It’s not just about being overweight or underweight. it’s rather about having a balanced composition of fat.

Types of Body Fat

When we think about body fat, it’s not just about the amount but also the type.

There are three key types to know: essential fat, storage fat and visceral fat. Both play different roles in our health, and here’s a summary look at what they do:

Essential Fat

• Definition: Essential fat is the minimum fat required for basic bodily functions. It’s found in muscles, central nervous system, bone marrow and organs.
• Purpose: This type of fat is vital for hormonal balance, including reproductive functions, nutrient absorption, temperature regulation and cushioning for organs.
• Healthy Levels: A small percentage of overall body fat is essential. Typically, this is around 2-5% in men and 10-13% in women, though these values can vary.

Storage Fat

• Formation: Storage fat develops when you consume more calories than your body can use. It’s stored throughout the body in adipose tissue.
• Roles and Risks: While it acts as an energy reserve, excessive storage fat can lead to health issues. It’s associated with an increased risk of conditions like heart disease, diabetes and joint problems.
• Managing Storage Fat: Keeping this fat in check involves a balanced diet and regular exercise. It’s not about eliminating it entirely, but managing it in a way that supports your overall health.
• Subcutaneous Fat: A form of storage fat located just beneath the skin. It’s the fat that you can pinch or feel externally.
• Some Visceral Fat: While visceral fat is a separate category due to its location and health implications, it can be considered part of the body’s storage fat when it’s within healthy levels.

Visceral Fat

• Location: Found deep within the abdominal cavity, surrounding vital organs like the liver and intestines​​.
• Health Risks: Excessive amounts are linked to serious conditions such as heart disease and diabetes​​.
• Control Measures: Proper diet and physical activity are key to managing visceral fat levels.

How to Measure Your Body Fat?

Gauging body fat percentage goes beyond simple scale readings. It involves exploring the deeper aspects of our body’s composition.

There are several methods to measure body fat, each with its own set of strengths and weaknesses.

Here, we dive into three popular techniques: Calipers, Bioelectrical Impedance Analysis (BIA) and Dual-Energy X-ray Absorptiometry (DEXA), to give you a clearer picture of how they work and what they offer.

Calipers

They are a popular method for estimating body fat percentage. They are cost-effective, easy to use and widely accessible.

You can even do the measurements at home. Calipers work by pinching the skin at specific sites on the body and measuring the thickness of the fat layer.

• Pros: Affordable, convenient and relatively accurate for most people.
• Cons: The accuracy depends on the skill of the person performing the measurement and the consistency of the measurement sites.

Bioelectrical Impedance Analysis (BIA)

BIA measures body composition by sending a low-level electrical current through the body. The resistance to this current provides data that is used to estimate body fat percentage.

• Pros: Non-invasive and quick. It provides a general idea of body composition.
• Cons: Not as accurate as some other methods. The results can be affected by factors like hydration levels and recent meals​.

Dual-Energy X-ray Absorptiometry (DEXA)

DEXA scans are considered one of the most accurate methods for assessing body composition. This scan uses low-level X-rays to differentiate between bone mass, lean mass and fat mass.

• Pros: Provides detailed information about body composition, including the distribution of muscle, fat and bone density. Requires minimal preparation and is non-invasive.
• Cons: More expensive and less accessible than other methods. Usually performed in medical or research settings.

Each method has its advantages and limitations. For those looking to get a general idea of their body composition, calipers or BIA might suffice.

However, for a more detailed analysis, particularly for professional health assessment or athletic training, a DEXA scan is a superior choice.

Healthy Body Fat Levels

When it comes to health, body fat percentage is a more telling indicator than weight alone.

This measure varies across genders and changes with age.

Ranges for men and women are as follows:

Women

The classification of body fat percentages for women is as follows:

• Under 15%: Low Body Fat Risk
• 15%-18%: Ultra Lean
• 18%-22%: Lean
• 22%-30%: Moderately Lean
• 30%-40%: Excess Fat
• Above 40%: High Body Fat Risk

Men

For men, the classification is slightly different:

• Under 5%: Low Body Fat Risk
• 5%-8%: Ultra Lean
• 8%-12%: Lean
• 12%-20%: Moderately Lean
• 20%-30%: Excess Fat
• Above 30%: High Body Fat Risk (Source)

These ranges offer a general guideline for healthy body fat levels.

However, it’s essential to note that individual health cannot be determined by body fat percentage alone.

The Influence of Age on Body Fat

As we grow older through different stages of life, our body’s composition evolves, reflecting changes in body fat percentages.

• During Adolescence: This period sees divergent body composition trends in boys and girls. Boys typically develop more muscle mass, which keeps body fat percentages lower. In contrast, girls tend to increase in body fat as part of their developmental process, which is both natural and essential for health.
• In Adulthood: For both genders, adult years mark a stabilisation period, where body fat percentages vary but generally stay within a certain range. This range, however, is influenced by lifestyle, diet and physical activity levels.
• Post-30 Changes: Around the age of 30, our bodies start to experience a shift. There’s a gradual loss in muscle mass due to a natural decline in metabolic rate. This physiological change often leads to an increase in body fat percentage, even if the physical weight doesn’t change significantly.
• Pregnancy Impacts: For women, pregnancy is a time of significant change. The body naturally accumulates more fat, a critical process for the health and development of the fetus.
• Mid-life and Later Years: Approaching middle age and later years, the tendency to gain weight differs between men and women. Men typically see weight increases until about age 55, while women may continue to experience this until around age 65. These changes are partly due to hormonal shifts and a further decrease in metabolic rate.

Impact of Excess Body Fat

Excess body fat can have profound implications on both physical and mental health.

Grasping the full range of these effects is vital for a comprehensive understanding of our health.

Physical Health Risks

• Type 2 Diabetes: Excess body fat significantly increases the risk of type 2 diabetes, a condition linked to elevated blood sugar levels. This can lead to further health complications like heart disease, stroke and kidney disease​​.
• High Blood Pressure: Obesity can lead to hypertension, where the heart works harder to pump blood, raising risks for heart attack, stroke, and kidney disease​​.
• Heart Disease: Being overweight increases the risk of several heart-related problems, including heart attack, heart failure and abnormal heart rhythms​​.
• Stroke: Excess weight is a known factor in increasing blood pressure, a leading cause of strokes​​.
• Metabolic Syndrome: This condition, related to obesity, can increase the risk of heart disease and diabetes​​.
• Liver Diseases: Obesity can lead to fatty liver diseases, potentially causing severe liver damage or liver failure​​.
• Certain Types of Cancer: Overweight and obesity are linked to an increased risk of cancers such as colon, rectum, prostate, breast, uterus and gallbladder cancers​​.
• Breathing Problems: Excess weight can affect lung function and increase the risk of breathing problems​​.
• Osteoarthritis: Obesity is a leading risk factor for osteoarthritis, particularly in the knees, hips and ankles​​.
• Gout: A type of arthritis, gout risk is increased with obesity, especially in men​​.
• Gallbladder Diseases: Obesity may raise the risk of gallbladder diseases, including gallstones​​.
• Kidney Disease: Obesity increases the risk of chronic kidney disease, even without the presence of diabetes or high blood pressure​​.
• Pregnancy Complications: Obesity during pregnancy can lead to gestational diabetes, high blood pressure and an increased risk of cesarean delivery​​.

Psychological Aspects

• Mental Health: Obesity can lead to long-term stress, body image issues, low self-esteem, depression and eating disorders​​.
• Social and Emotional Impacts: Overweight individuals often face weight-related bias, which can affect their quality of life, relationships and emotional well-being​​.

How to Reduce Body Fat Safely?

Balanced Diet

A balanced diet is essential in managing body fat. Here are some important aspects that should be kept in mind:

• Variety and Moderation: Incorporate a diverse range of foods in your diet, including fruits, vegetables, whole grains, lean proteins and healthy fats.
• Portion Control: Be mindful of portion sizes to avoid overeating, even when consuming healthy foods.
• Limiting Processed Foods: Reduce intake of processed foods high in added sugars and unhealthy fats.
• Hydration: Drinking enough water is key to a healthy metabolism and can help control hunger.
• Consistency: Maintaining a balanced diet consistently is more effective than short-term dieting.

Exercise

Exercise is important for reducing body fat and improving one’s overall health, to say the least!

• Regular Activity: Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week, along with strength training exercises.
• Mix of Cardio and Strength Training: While cardio exercises are effective in burning calories, strength training helps build muscle, which can increase metabolism.
• Personalised Routine: Choose exercises that you enjoy and suit your fitness level to ensure consistency.
• Incremental Progress: Increase the intensity and duration of workouts gradually to avoid injury and build endurance.
• Rest and Recovery: Adequate rest is important for muscle recovery and one’s overall health.
