Whether 23 percent body fat is “bad” depends almost entirely on whether you’re male or female. For women, 23% falls squarely in the general fitness range and is a healthy, solid number. For men, 23% sits just below the threshold where researchers start flagging increased health risks, placing it in the “average” category but not yet in overweight territory.
What 23% Means for Women
For women, 23% body fat is in the general fitness range (20 to 24%), which sits between the leaner athletic range and the broader “acceptable” category of 25 to 29%. This is a level associated with good health, normal hormone function, and an active lifestyle. There’s nothing concerning about this number for a woman at any adult age. In fact, a 2025 study using US national survey data didn’t define “overweight” for women until 36% body fat, and “obesity” at 42%. At 23%, you’re well below those thresholds.
What 23% Means for Men
For men, 23% body fat falls in the average or acceptable range (roughly 19 to 25%), but it’s on the higher end. The athletic range for men is 12 to 19%, and the general fitness range is about 14 to 17%. That same 2025 study defined “overweight” for men as 25% body fat and “obesity” at 30%. So at 23%, a man is close to the overweight cutoff but not there yet.
This doesn’t mean 23% is dangerous for a man. Plenty of men carry this level of body fat and have perfectly normal blood pressure, blood sugar, and cholesterol. But it does place you in a zone where small increases could start to matter, especially if you’re also carrying fat around your midsection.
Age Changes the Picture
Body fat naturally increases with age, even in people who maintain the same weight. Adults over 60 tend to carry higher body fat percentages partly because muscle mass decreases over time. Research in the American Journal of Clinical Nutrition found that after accounting for BMI, older age consistently predicted higher body fat, with this effect being more pronounced in men than women.
What this means practically: 23% body fat in a 55-year-old man is more typical (and less concerning) than 23% in a 25-year-old man who doesn’t exercise. There’s no single universal cutoff, and context matters.
Where the Fat Sits Matters More Than the Number
A body fat percentage is a single number that tells you nothing about where that fat is stored, and location turns out to be critical. About 90% of body fat in most people is subcutaneous, the soft layer just under your skin. The other 10% is visceral fat, packed deep around your liver, intestines, and other organs.
Visceral fat is biologically active in ways that subcutaneous fat is not. It functions like an endocrine organ, pumping out inflammatory proteins called cytokines that raise the risk of heart disease. It also produces molecules that constrict blood vessels and raise blood pressure. Higher visceral fat is linked to elevated blood sugar, higher triglycerides, and lower levels of good cholesterol. Taken together, these changes define metabolic syndrome, a cluster of conditions that sharply raises your risk of cardiovascular disease and type 2 diabetes.
The implications go beyond heart health. Kaiser Permanente researchers found that people in their early 40s with the most abdominal fat were nearly three times more likely to develop dementia by their 70s and 80s compared to those with the least. In a large study of California teachers, women with waist circumferences above 35 inches were 37% more likely to develop asthma, even when their overall weight was normal.
So two people can both measure at 23% body fat and have very different risk profiles. If your waist is relatively trim and you carry fat mostly in your hips, thighs, and under the skin, 23% is a fairly benign number. If most of your fat is concentrated around your belly, it’s worth paying closer attention regardless of what the percentage says.
When Body Fat Percentage Starts to Affect Health
The serious health risks linked to excess body fat, such as type 2 diabetes, heart disease, stroke, fatty liver disease, and high blood pressure, are associated with overweight and obesity levels, not with moderate body fat in the average range. Nearly 9 in 10 people with type 2 diabetes have overweight or obesity. Excess body fat forces the heart to work harder to circulate blood, can damage the kidneys (which regulate blood pressure), and raises the risk of fat accumulation in the liver that can progress to cirrhosis.
At 23%, neither men nor women are in the obesity range by any widely used classification. For men, it’s a yellow light rather than a red one: healthy today, but worth monitoring. For women, it’s a green light.
How to Use This Information
If you’re a woman at 23% body fat, you’re in a healthy fitness range and there’s no reason to try to lower it unless you have specific athletic goals. Dropping below about 12% as a woman can actually disrupt menstrual cycles and bone health.
If you’re a man at 23%, you’re in an acceptable range but have room for improvement if you want to reduce health risk or improve how you look and feel. The most effective approach is building muscle through resistance training, which both lowers your body fat percentage and specifically targets visceral fat. Even without losing weight on the scale, shifting your body composition toward more muscle and less fat improves metabolic markers like blood sugar and cholesterol.
Regardless of sex, measure your waist circumference as a simple check on visceral fat. For men, a waist above 40 inches signals elevated risk. For women, the threshold is 35 inches. If your body fat percentage is 23% but your waist is well under these numbers, your overall risk profile is likely favorable.
