What is the range of body fat content for noraml weight men?

What do you mean by the "acceptable body fat range" for men? Do you mean "healthy"? If so, the answer would depend on your age. If you are 20 to 40 years old, then a healthy body fat range would be from 8% to 19%. If you are 41 to 60 years old, the healthy range is 11% to 22%. If you are 61 to 79 years old, the healthy range is 13% to 25%.
