5 to 9% If your body is only between 5 to 9%, your body fat is dangerously low. Eight per cent is usually the fat essential for your body to work – and may severely compromise your health.
It can safely go as low as 10% for women and 3% for men, according to the American College of Sports Medicine (ACSM). With that said, normal body fat percentage ranges that are generally considered healthy for both men and women are provided in the chart below.
According to Pennsylvania State University, the average guy's body fat is 15-20, 3% of which is “essential,” meaning you'd die without it. “A body-fat percentage below 5% is regarded as a warning sign of poor health, even in elite athletes,” says Georgie Fear, R.D., author of Lean Habits for Lifelong Weight Loss.
For people aged 20 to 39, women should aim for 21% to 32% of body fat. Men should have 8% to 19%. For people 40 to 59, women should fall between 23% to 33% and men should fall around 11% to 21%. If you're aged 60 to 79, women should have 24% to 35% body fat and men should have 13% to 24%.

How many kilograms are in 1% body fat? This depends on your body weight. To convert body fat percentage to kilograms, multiply the body fat percentage by total body weight. If you weigh 80 kg and are 20% body fat, 20% of your body composition is body fat.
Men require at least 3 percent body fat and women at least 12 percent in order for the body to function properly, Garber said. Below that is where you start to see serious health problems. Sometimes it leads to organ failure and death, she added.
Weight loss, it turns out, boosts your testosterone levels. In fact, if you're overweight (or obese) and have low T levels, taking off some of those pounds is one of the best things you can do to get higher T levels.
Your veins start to show when your body is at around 10 percent body fat. But, to maximize vein expulsion, your body fat should be below 8 percent. At such a lower body fat percentage, there is practically nothing between your muscles and skin that helps in putting those veins on display.

There's fat inside our bodies in places you may not be aware of, like the brain, nerves, and surrounding organs. "It is impossible to have zero percent body fat," says Dr. Sutterer.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
2. Your Abdominal Muscles Aren't Thick Enough. If you have a trim waist and minimal body fat and you still can't see your abs, then you need to work on getting the Rectus Abdominis (your 6 pack muscle) thicker. You will never be able to see your abs if the muscle bellies there are weak and small.
Cold intolerance is a frequent complaint among those who have lost a considerable amount of weight. The body's core has lost a significant part of its protection against heat loss. The problem is usually worse for those who become very thin, especially small women.

If you place 1kg of muscle on a scale and 1kg of fat on a scale, they will both weigh 1kg. The difference is in total volume. 1 kg of muscle may appear to be the size of baseball whilst 1kg of fat will be three times the size and look like a wobbly bowl of Jelly.
I highlighted that to burn 20kg of fat, which is 180,000 calories, they'd need to run a 5k (3 miles for the yanks) three hundred and sixty times.
"You need a certain amount of essential fat—3%—which is found in the vital organs and is essential for normal functioning in a guy. Consequently, the minimum healthy percent body fat a man can achieve is around 3%, typically seen in endurance athletes, but also bodybuilders on competition day, Jordan explains.
There is more fat all around the body at the 30% level including waist, back, thighs, and calves. The waist looks larger relative to the hips, and the stomach will likely be protruding over the waist noticeably. There is no muscle separation.
The study found that 12% was the most attractive body fat percentage. Attractiveness by body fat followed a bell-shaped curve: 12% body fat is optimum. If you exceed this value, you become less attractive as your body fat percentage increases. Less body fat than 12%, however, also reduces attractiveness.
About 15% of the general population have 4-pack abs, while 2% can only ever achieve a 2-pack. Then, even rarer than the 2-pack is a total of 10 or even 12 abdominal muscles, meaning 5 or 6 bands of the connective fascia.
