Question 1

What is a healthy BMI for seniors in Singapore?

Accepted Answer

For adults over 65, some guidelines suggest a slightly higher healthy BMI (up to 23–24) may be protective against frailty and malnutrition. Consult your doctor for personalised advice.

Question 2

Is being underweight dangerous for seniors?

Accepted Answer

Yes. Underweight seniors (BMI <18.5) are at higher risk of muscle loss, falls, fractures, and malnutrition. Maintaining muscle mass is especially important after 60.

Question 3

Should seniors aim to lose weight to lower BMI?

Accepted Answer

Not necessarily. Seniors should avoid rapid weight loss without medical supervision as this can cause muscle loss. Focus on maintaining muscle through protein intake and activity.

Question 4

Does BMI become less accurate with age?

Accepted Answer

Yes. Older adults tend to have less muscle and more body fat at the same BMI. Body composition assessment (waist circumference, muscle mass) gives a more complete picture.
