Today, we're going to show what different body fat percentages actually look like and what
0:04
diet and exercise typically accompany each level. Let's start all the way at the top.
0:08
The highest body fat percentage ever recorded, according to the Guinness Book of World Records,
0:13
was 80%. At that level, fat covers nearly every muscle and bone in the body. Movement is extremely
0:19
limited. Breathing, sleeping, and even sitting upright become difficult. This isn't a lifestyle
0:24
category. It is a medical outlier, usually involving severe illness and fluid retention.
0:29
So, instead of staying here, let's move on quickly to levels that people actually reach. At 50% body
0:34
fat, both men and women are classified as morbidly obese. Fat visibly hangs over the abdomen, hips,
0:40
chest, and thighs, obscuring muscle definition entirely. At this level, everyday movement is
0:45
exhausting. Walking, climbing stairs, and sleeping comfortably are pretty difficult.
0:49
Diets here are typically very high in calories, dominated by ultrarocessed foods, with little
0:54
to no structured exercise. So, while women are classified as severely obese at over 45% body fat,
1:00
men are severely obese at over 40% body fat. So, at 50% men are way over the healthy line.
1:07
One man at the 50% range described his experience in carrying the excess weight around. I'm always
1:12
tired. I'm just always fatigued. But this is still only the beginning of the scale. Do things
1:18
improve at the 40% range? A little, especially for women. Men are still classified as morbidly obese,
1:24
while women have shifted down to just obese. Women have hips that are noticeably wider than
1:28
their shoulders at this body fat percentage, but they're probably not experiencing as many
1:32
challenges when it comes to simple movements like going upstairs, sleeping, bending over,
1:36
or general fatigue. At that body fat percentage, men still have a noticeable amount of extra fat,
1:42
mostly around the stomach area, as well as some in the upper body as well. Women with 40% body
1:47
fat can look all sorts of different ways and have different diet and exercise habits. On some women,
1:52
the fat is distributed more evenly, resulting in a woman that may look big but not necessarily
1:56
unhealthy. While others, particularly those who aren't as mobile and don't work out,
2:01
may still have lots of noticeable extra fat on the upper arms, stomach, hips, and thighs. Men with
2:06
this body fat percentage, have a significantly higher risk of heart disease, high blood pressure,
2:11
stroke, diabetes, and other obesity related issues. Women also have an elevated risk as well,
2:16
but it is slightly reduced. The bad news is if you're in the US at least, the average American
2:22
woman sits at around 39% body fat, and that falls into the obese category. For many people watching,
2:28
this is the range that they're closest to right now. When we get down to 30% body fat,
2:32
things change a lot for men as well. At this percentage, a man's lean mass can seriously affect
2:37
their health and appearance. In one test, two men had the same body fat percentage, about 33%,
2:43
but looked very different. One had 97 lbs of lean mass. The other had closer to 150 lbs. Even
2:49
with the same body fat percentage, the second man looked far more in shape and was a regular at the
2:54
gym. Men with more lean body mass should have pretty normal energy levels, gym performance,
2:59
and look more toned overall at 30%. Even though they do still face some health risks. In the US,
3:05
about 40% of men are in this range. This is the point where body fat stops being purely
3:10
visual and starts affecting long-term health. At around 30% body fat, this is where age starts
3:16
to visibly change what the same percentage looks like. As both men and women get older,
3:21
their ability to build muscle and metabolize food fast suffers. Their muscle mass and their bone
3:26
density also generally deteriorates, so their body fat percentage naturally will go up. But it's not
3:32
just okay to increase body fat reserves as you get older. It's actually recommended. Body fat
3:37
offers your body and health protection. It acts as an energy reserve during illnesses and periods of
3:42
weakness or low appetite. Both things that affect people more often as they age. Carrying some extra
3:47
body fat gives your body energy reserves it can use during physically difficult times,
3:52
helping support your immune system and fight off disease. If you are older and lean, your body has
3:57
less fat to draw from. That means healing and recovery can take longer. In extreme cases,
4:02
your body might start breaking down necessary tissue like muscle for energy. This matters when
4:07
you look at what's considered normal. The average US male sits at around 27% body fat. For men aed
4:13
20 to 49, that is classified as obese. But once you pass 50, that exact same percentage suddenly
4:19
falls into an acceptable range. For women, the contrast is even sharper. At 30% body fat, women
4:25
are considered to be in the optimal range toward the higher end, but still completely healthy. Even
4:30
in the youngest adult group, ages 20 to 29, women aren't classified as obese unless they're above
4:35
32% body fat. This is why you'll see plenty of women in the gym who look fit, eat balanced diets,
4:41
and don't aggressively restrict food and would still land near 30% body fat. In fact, in the US,
4:47
only about 10% of women are leaner than that. That said, a woman could be at 30% body fat
4:52
while barely exercising and living on takeout. And this is where individual differences really start
4:58
to matter. One quick note before we go lower. This explains why two people at the same body
5:03
fat percentage can look very different and face very different health risks. Body fat distribution
5:08
varies by genetics and ethnicity, which is why people at the same body fat percentage or BMI can
5:14
look very different and face very different health risks. This is one reason that BMI alone isn't a
5:19
reliable measure of health. With that in mind, let's keep moving down the scale. 20% body fat.
5:25
What does that look like in men? Some men have defined muscles, especially around their arms and
5:29
shoulders, and a noticeably toned physique. Others might have a body closer to what people call
5:34
skinny fat, an overall thin frame with a belly and extra fat around places like the upper chest and
5:39
arms. Only 12% of men are at or under this body fat percentage. For some men, this is the range
5:45
where they feel the healthiest, happiest, and most energetic, and that can be influenced by past
5:50
physical condition. But genetics plays the largest role. People's genes generally create a set range
5:55
at which their body will feel, look, and perform at its best. This can vary by a few percentage
6:00
points from one person to the next. That's also why people can look very different at the exact
6:04
same body fat percentage. One study of different ethnic groups by the International Journal of
6:08
Obesity found that groups of people at the same age, gender, and body fat percentage can have very
6:14
different BMIs. When matched for body fat, age, and sex, black Americans had BMIs about 1.3 points
6:21
lower than Caucasians, while Polynisians were lower by roughly 4 and a half points. In other
6:26
words, two people with the same BMI can have very different body fat levels, especially Polynesians
6:32
who tend to carry significantly more fat at the same BMI. Chinese, Ethiopian, Indonesian, and
6:37
Thai groups were also studied, and they all had lower BMIs than the Caucasian group by roughly 2
6:43
to 5 points. This points to genetic differences in body build and energy usage. That's why BMI isn't
6:49
always the best indicator of overall health. It doesn't take into account muscle mass or genetic
6:54
differences. And research eventually figured out why. South Asian populations tend to have smaller
6:59
frames and store a greater share of their body fat deep around their organs rather than just under
7:04
the skin. All of this highlights how strongly genetic shapes where fat is stored and how much
7:09
of it we carry and how that fat translates into health risks over time. And the lower you go on
7:14
the scale, the more those differences matter. At 20%, we're already in a really small group when it
7:19
comes to women because women look pretty fit at this level of body fat. Most will have somewhat
7:24
defined abs and noticeable muscles. In fact, most female athletes sit around 20% body fat,
7:30
except gymnasts who tend to have way lower levels, as you'll soon see. And that may not be a great
7:35
thing. 20% body fat is so rare that only 2% of US women even have a body fat percentage under 25%.
7:42
Even though it's quite lean, it's still a percentage that women can maintain while
7:46
staying healthy, happy, and most importantly, not dieting in overly strict ways as long as they're
7:51
exercising consistently and mostly following a healthy meal plan. So 20% on women is lean,
7:57
but still in a healthy range. That's not the case when we start to dip below that range. At 15%,
8:03
women start to enter potentially dangerous territory. Here, the body starts actively
8:07
resisting further fat loss. While their muscles will look very defined, it's generally recommended
8:12
women don't stay in this range for too long. Usually 15% is a result of professional athletes
8:18
training for a specific event. Of course, it also depends on the type of athlete. A study by Human
8:23
Kinetics in Canada found that female basketball players have body fat ranges of 20 to 27% on
8:29
average, tennis players sit at 16 to 24%, and swimmers at 14 to 24%. On the other hand, gymnasts
8:36
generally have body fat levels of 10 to 16% and marathon runners have 10 to 15%. Which might not
8:43
be great news. If women stay in this range for a while, they can temporarily lose their menstrual
8:48
cycle and see a decrease in their overall energy levels. After a while, their bone mineral density
8:53
will fall and their gut health will also be negatively affected. Hunger levels definitely go
8:58
up as your body fights to get body fat back on. So maintaining this percentage will also feel like a
9:03
huge chore. Since women's essential body fat lies between 10 and 12%, 15% can get dangerously close
9:10
to that for most. Quite a few men, on the other hand, can get to this body fat percentage with
9:14
regular gym sessions that include weightlifting and generally watching their diet, mostly cutting
9:19
out lots of sugars, fats, and processed and junk food. How easy it is to maintain depends largely
9:25
on genetics and where someone is starting from. Dropping to 15% body fat from a very high weight
9:30
is far harder than coming down from a more average range. Men who are naturally lean and build muscle
9:36
easily will have a much easier time staying there. Of course, you don't have to be a gym
9:40
rat to be at 15%. You could just be a pretty thin 20-year-old guy. If you don't really work out,
9:45
you'll know that you're at 15% if you have a flat stomach and some faint muscle definition. When it
9:50
comes to American men, only 2% of them fall at or below this body fat level. And even fewer men
9:56
fall at or below the next body fat percentage, 12%. After this point, almost no one stays here
10:02
accidentally. Even if men can reach that body fat range, maintaining it is much harder. That kind of
10:07
body composition usually means strict, repetitive meal prep. The infamous chicken, rice, and
10:12
broccoli inexplicably cooked without seasoning. Not everything has to be self-punishment,
10:18
guys. Maintaining this weight takes a lot of discipline, almost no deviation from a very
10:22
consistent, challenging workout schedule. and a strict meal plan. The difference between 12 and
10:27
15% for those men is that at the former level, you can start to see some ab definition, not because
10:33
you've been killing it at the gym, but because you literally don't have enough fat to cover your ab
10:37
muscles. As for women, 12% body fat is squarely in bodybuilding territory. And that's being generous.
10:44
For many women, reaching that level isn't even possible without drugs. While someone may look
10:49
extremely muscular at this percentage, energy levels and athletic performance tend to drop off
10:53
fast. At 12%, body fat is almost entirely about appearance, not function. Outside of bodybuilding,
11:00
you mainly see numbers this low in intensive gymnastics or similar sports. And then even there,
11:05
it often comes with missed periods and other negative health effects. Not to mention the hunger
11:10
pangs. A huge chunk of your day will just be you fantasizing about food. That's because women
11:15
with this amount of body fat are barely staying above their essential fat levels. Speaking of,
11:20
let's go a bit lower. 10%. Men who work out look jacked here. They have clearly defined six-packs.
11:27
They have muscle striations all over the place. But at this point, even men really can't step
11:32
out of line at all when it comes to your meal and fitness routine. With the exception of a rare few
11:37
men who thrive at that level because they have the genetics of a pro alete. The probability of that
11:43
being you is slim. And if you're at 10% as just a very thin man, you might want to look at putting
11:48
on some weight. You will probably have very visible abs and muscles, but you also will look
11:53
much thinner than the gym bro, mostly because you haven't built up your lean muscle mass. For women,
11:58
10% is the minimum amount of body fat percentage that is biologically possible. At that point,
12:03
you're down to the lowest point of your essential fat. It is really, really not
12:07
recommended to go below that or even get there. Honestly, women who are actively bodybuilding
12:13
in preparation for a competition might get down to this body fat percentage for a bit.
12:17
They'll likely stop menrating and face more extreme health risks. Many report losing their
12:22
hair. Their brain is also basically a slideshow of Ben and Jerry's flavors at this point as their
12:27
body begs them to take in any fat at all. At this point, the body is no longer cooperating. It is
12:32
surviving. At around 8% body fat, men can start to lose their sex drive, struggle with sleep,
12:38
and even have trouble thinking clearly. Why? Because the body interprets this as starvation
12:42
and puts everything else on hold until the food shows up. Your brain will be fixated on finding
12:48
a nice fatty meal 24 hours a day. Everything else is brain fog. Energy levels are also down because
12:54
food intake is being severely restricted both in terms of calories and also to the blandest
12:59
meals available. At this point, you're ready to hand over your savings account for a happy meal.
13:04
The reason men lose their sex drive at lower body fat percentages is similar to the reason
13:08
why women lose their periods. Their bodies have made an executive decision that there
13:12
is clearly no time to have a kid as you can't even get enough food to keep yourself alive. So,
13:17
your body focuses all your thoughts, internal processes, and energy on getting food for you
13:22
first, putting everything else on the back burner. Women at 8% don't really exist. And if they do,
13:28
it is so incredibly unhealthy that it's basically life-threatening. The last level we'll look at for
13:33
men is one that also is borderline dangerous, especially if kept for a long time. 5% 5% body
13:39
fat is incredibly hard to achieve. Many men who have gotten down to this level needed steroids
13:44
or other performance-enhancing drugs to get anywhere near it. As men's body fat percentage
13:49
starts to dip below 8%, their body really panic shifts into survival mode. It starts to burn off
13:55
everything it can, including muscle, to stay alive and well, because your body doesn't understand why
14:00
you just wouldn't eat. Now that we've gone through all the different possibilities,
14:03
what body fat percentage range should people generally aim for? The American College of Sports
14:08
Medicine says the best body fat percentage range for women is 20 to 32%, for men, that range is 10
14:13
to 22%. For most people, staying in that range is already doing better than average. Now go check
