Whether 28% body fat is “bad” depends almost entirely on whether you’re male or female. For women, 28% falls squarely in the acceptable, healthy range. For men, 28% is above the overweight threshold and into a range that can increase health risks over time.
What 28% Means for Women vs. Men
Body fat standards differ significantly between sexes because women carry more essential fat for reproductive and hormonal functions. Women need roughly 12% body fat just for basic physiological processes, compared to about 3% for men. That biological difference shifts every category upward for women.
Here’s how standard classifications break down:
- Athletic: 5–10% for men, 8–15% for women
- Good: 11–14% for men, 16–23% for women
- Acceptable: 15–20% for men, 24–30% for women
- Overweight: 21–24% for men, 31–36% for women
- Obese: above 24% for men, above 37% for women
For a woman, 28% sits comfortably in the acceptable range, closer to the middle. There’s nothing alarming about it. For a man, 28% is above the overweight cutoff and approaching the obesity threshold. A 2025 study using US national survey data defined overweight as 25% body fat or higher for men and 36% or higher for women, which puts a man at 28% clearly in overweight territory by that definition too.
Age Changes the Picture
Body fat naturally increases with age, even if your weight stays the same. This happens partly because muscle mass declines over time, shifting your body’s ratio of fat to lean tissue. In adults 60 and older, body fat percentages tend to run higher than in younger adults. So 28% in a 25-year-old man carries different implications than 28% in a 65-year-old man. The younger person likely has more room and reason to bring that number down, while the older person may be closer to a realistic, functional range for their age.
Where the Fat Sits Matters More Than You’d Think
Two people can both measure 28% body fat and have very different health profiles depending on where that fat is stored. Fat distributed across your hips, thighs, and just beneath the skin (subcutaneous fat) is relatively benign. About 90% of body fat in most people is this type. The remaining 10%, called visceral fat, sits deep in the abdomen around your organs, and it’s the kind that drives disease risk.
Visceral fat is metabolically active in ways that subcutaneous fat isn’t. It produces inflammatory proteins called cytokines, which contribute to chronic low-grade inflammation. It also releases a precursor to a protein that constricts blood vessels and raises blood pressure. The result is a cluster of problems: higher blood sugar, elevated triglycerides, increased blood pressure, and lower levels of protective HDL cholesterol. Together, these changes are known as metabolic syndrome, and they significantly raise your risk of heart disease and type 2 diabetes.
The downstream effects go beyond cardiovascular health. Research from Kaiser Permanente found that people in their early 40s with the highest levels of abdominal fat were nearly three times more likely to develop dementia by their mid-70s compared to those with the least. A large study of California teachers found that women with waist circumferences over 35 inches were 37% more likely to develop asthma, even if their overall weight was normal. In a study of European women aged 45 to 79, those with the largest waists had more than double the risk of heart disease, and every additional 2 inches of waist size raised cardiovascular risk by 10%.
A simple waist measurement gives you a rough sense of where you stand. For men, a waist circumference over 40 inches suggests elevated visceral fat. For women, the threshold is 35 inches.
Your Measurement May Not Be Exact
Before making any changes based on a 28% reading, it’s worth considering how that number was measured. Common methods like skinfold calipers and bioelectrical impedance (the handheld devices or scales that send a small electrical current through your body) carry a standard error of around 3.5%. That means your true body fat could reasonably be anywhere from about 24.5% to 31.5%. Hydration levels, recent meals, and time of day can all shift readings from these tools.
DEXA scans, which use low-dose X-rays, are more precise but still not perfect, and they’re less accessible. If your 28% came from a bathroom scale or a gym assessment, treat it as a useful estimate rather than a definitive number. Tracking trends over time with the same device and conditions is more informative than fixating on a single reading.
How 28% Affects Physical Performance
From a functional standpoint, higher body fat lowers your work-to-weight ratio. A heavier body consumes more energy per minute of activity, which reduces efficiency during exercise, especially cardio. Extra weight also places additional load on joints during activities like running or hiking, increasing the risk of joint stress over time. This doesn’t mean 28% makes you unfit. Plenty of people at that body fat percentage are active and capable. But if you’re trying to improve endurance, speed, or agility, reducing body fat toward the “good” range for your sex will generally help.
Going too far in the other direction carries its own risks. Very low body fat impairs immune function, making you more susceptible to illness. In women, dropping body fat too low causes estrogen levels to fall, which can lead to bone loss and increase fracture risk later in life.
What You Can Actually Do With This Number
If you’re a woman at 28%, you’re in a healthy range. You could aim to move toward the “good” category (16–23%) for athletic or aesthetic goals, but there’s no urgent health reason to do so based on that number alone.
If you’re a man at 28%, bringing that number down is worth pursuing. The most effective approach combines resistance training, which builds or preserves muscle mass, with a moderate calorie deficit. Resistance training matters here because losing weight through diet alone tends to shed muscle along with fat, which can leave your body fat percentage stubbornly unchanged even as the scale drops. Prioritizing protein intake helps preserve lean tissue during fat loss.
Regardless of your sex, pay attention to waist circumference alongside body fat percentage. A normal body fat reading paired with a large waist measurement can still signal elevated visceral fat and metabolic risk. And if your reading came from a consumer-grade device, consider getting retested with the same method in a few months to see which direction you’re trending rather than treating 28% as a fixed verdict.
