How much body fat should a 33-year-old woman have?

As a female, your percentage of body fat should be about 15 to 20% for good health. (For males the percentage of body fat should be about 10 to 15% for good health.) To determine your percentage of body fat at home, obtain some plastic body fat calipers and do a simple skin-fold test. Body fat calipers are not expensive, are readily available to buy, and can replace a scale or balance.
