Frequently Asked Questions
What is healthy body fat % for Singaporean men?
According to ACE (American Council on Exercise) categories, acceptable body fat for men is 18–24%, with the fitness category at 14–17% and athlete category at 6–13%. For Singaporean men, Singapore HPB and clinical guidelines align with these ACE categories. Men with body fat above 25% are classified as obese and carry significantly elevated risk for type 2 diabetes, cardiovascular disease, and metabolic syndrome — all of which are major public health priorities in Singapore.
How do men measure body fat with a tape measure?
For men, the US Navy method requires two measurements: (1) Waist circumference — measured horizontally at the navel level while relaxed, not sucked in; (2) Neck circumference — measured just below the larynx (Adam's apple), perpendicular to the neck's axis. Use a flexible tape measure and take each measurement twice, averaging the results. Measure at the same time of day — morning before eating is most consistent.
