Your body fat percentage matters more than the number on the scale. It shows how much of your body is fat versus muscle, bone, and organs. Many people focus only on weight. This is a mistake. Two people can weigh the same but look completely different based on their body fat levels.
Body fat percentage changes as you age. Your ideal range depends on whether you are male or female. It also depends on your fitness goals. Some people want to see their abs. Others just want to stay healthy. Both goals are valid. Both need different body fat targets.
Why Does Body Fat Percentage Matter?
Body fat affects your health in major ways. Too much body fat increases your risk of heart disease, diabetes, and high blood pressure. Research shows that people with healthy body fat levels live longer. They have more energy. They move better. They feel better.
But too little body fat causes problems too. Your body needs some fat to work properly. Fat protects your organs. It helps make hormones. It keeps you warm. Women need more body fat than men because of how their bodies work.
The scale lies to you every day. It cannot tell the difference between fat and muscle. You might lose fat and gain muscle. The scale stays the same. You look better. You feel stronger. But the scale makes you think nothing changed. This is why what should my body fat percentage be for my age becomes the right question to ask instead of just tracking weight.
What Is a Healthy Body Fat Percentage for Men?
Men store less body fat than women naturally. Here are the healthy ranges for men at different ages:
Ages 20-39:
- Athletes: 6-13%
- Fitness: 14-17%
- Average: 18-24%
- Above Average: 25-29%
- High Risk: 30% and above
Ages 40-59:
- Athletes: 11-16%
- Fitness: 18-21%
- Average: 22-27%
- Above Average: 28-32%
- High Risk: 33% and above
Ages 60-79:
- Athletes: 13-18%
- Fitness: 19-22%
- Average: 23-28%
- Above Average: 29-33%
- High Risk: 34% and above
Men gain body fat as they age. This happens because testosterone drops. Muscle mass decreases. Metabolism slows down. You burn fewer calories doing the same activities. This is normal. But you can fight it with strength training and good nutrition.

What Is a Healthy Body Fat Percentage for Women?
Women need more body fat than men. This is not a flaw. It is biology. Women need extra fat for hormone production and potential pregnancy. Here are the healthy ranges:
Ages 20-39:
- Athletes: 14-20%
- Fitness: 21-24%
- Average: 25-31%
- Above Average: 32-37%
- High Risk: 38% and above
Ages 40-59:
- Athletes: 16-23%
- Fitness: 24-27%
- Average: 28-34%
- Above Average: 35-40%
- High Risk: 41% and above
Ages 60-79:
- Athletes: 18-25%
- Fitness: 26-29%
- Average: 30-36%
- Above Average: 37-41%
- High Risk: 42% and above
Women often worry about these numbers being higher than men. Stop worrying. Your body works differently. Lower body fat percentages can stop your period. They can weaken your bones. They can mess up your hormones. Healthy is better than skinny.
How Do You Measure Body Fat Percentage?
Several methods exist to measure body fat. Some are accurate. Some are not. Here are your options:
DEXA Scan:
This is the gold standard. It uses X-rays to measure bone, muscle, and fat. It costs between $100-$200 in Australia. It gives you exact numbers. Many sports science labs and some medical centres offer this service.
Bioelectrical Impedance:
These are the scales you stand on. They send a small electrical current through your body. They are cheap. You can buy one for $50-$300. But they are not very accurate. Hydration levels change the results dramatically.
Skinfold Calipers:
A trainer pinches your skin at specific spots. They measure the thickness. This costs $30-$80 at most gyms. Accuracy depends on the person doing the measuring. The same person should measure you each time.
Bod Pod:
You sit in a special chamber. It measures air displacement. This costs $80-$150 per test. It is very accurate. Not many places have this equipment.
What Happens When Body Fat Gets Too High?
High body fat creates serious health problems. Your heart works harder. Your joints carry extra weight. Your body becomes inflamed. Insulin stops working properly. This leads to type 2 diabetes.
Research from the American College of Sports Medicine shows that reducing body fat by just 5-10% improves health markers significantly. Blood pressure drops. Cholesterol improves. Blood sugar stabilises. Energy increases.
Visceral fat is the most dangerous type. This is the fat around your organs. You cannot see it. But it pumps out inflammatory molecules. These molecules damage your heart and blood vessels. They increase your risk of early death.
What Happens When Body Fat Gets Too Low?
Very low body fat causes different problems. Your immune system weakens. You get sick more often. Your bones become brittle. Women stop having periods. Men produce less testosterone.
Athletes sometimes drop their body fat too low for competitions. This is temporary. They do not stay at these levels year-round. Staying at very low body fat percentages for long periods damages your health.
Your brain needs fat to function. Hormones need fat to form. Your body temperature regulation needs fat. Going too low is just as dangerous as going too high.
How Can You Change Your Body Fat Percentage?
Changing body fat requires two things: strength training and nutrition. Cardio alone will not get you there. You need to build muscle while losing fat.
Strength Training:
Lift weights three to four times per week. Focus on compound movements like squats, deadlifts, and presses. These exercises build the most muscle. More muscle means higher metabolism. Your body burns more calories even at rest.
Protein Intake:
Eat 0.8 to 1 gram of protein per pound of body weight daily. Protein builds muscle. It keeps you full. It burns more calories during digestion than carbs or fats. Good sources include chicken, fish, eggs, and Greek yogurt.
Calorie Deficit:
To lose fat, you must eat fewer calories than you burn. But do not crash diet. Aim for a deficit of 300-500 calories per day. This leads to steady fat loss of 0.5-1% of body weight per week. Faster loss means you lose muscle too.
Walking:
Walk 8,000 to 12,000 steps daily. Walking burns calories without making you exhausted. It does not interfere with your strength training recovery. It is the most underrated fat loss tool.
Frequently Asked Questions
How long does it take to change body fat percentage?
You can safely lose 0.5-1% body fat per month. Faster loss usually means you are losing muscle too. A realistic goal is 5-10% body fat reduction over six months with consistent training and nutrition.
Can you spot reduce body fat?
No. Your body decides where it stores and loses fat. Genetics control this. You cannot do crunches to lose belly fat specifically. You must reduce overall body fat through diet and exercise.
Does age make it harder to lose body fat?
Yes. Metabolism slows by about 2-3% per decade after age 30. Muscle mass decreases. Hormones change. But you can still lose fat at any age. It just requires more attention to strength training and protein intake.
Should I focus on body fat percentage or weight?
Focus on body fat percentage. Weight includes muscle, bone, water, and organs. Two people at the same weight can look completely different. Body fat percentage tells the real story about your health and fitness.
How often should I measure body fat?
Measure once per month maximum. Body fat changes slowly. Daily or weekly measurements show too much variation from water retention and other factors. Monthly measurements show real progress.
The Bottom Line
Your ideal body fat percentage depends on your age, sex, and goals. Men should aim for 14-24% in their 20s and 30s. Women should target 21-31% in the same age range. These ranges increase slightly as you age.
Focus on building muscle and losing fat slowly. Quick fixes do not work. Sustainable changes in strength training and nutrition create lasting results. Measure your progress monthly. Track how you feel and perform, not just the numbers.
Your body fat percentage matters more than your weight. It predicts your health better than any scale. It shows whether your training works. It guides your nutrition decisions. Start measuring it today.
