How much protein do I need?

For average Singaporean adults aged 18-49, the recommended daily protein intake is approximately 0.8g/kg body weight.
Meanwhile, older adults aged 50 and above have a higher daily recommended protein intake at 1.2g/kg bodyweight instead. 

Age	Protein required
18 to 49	0.8g protein per Kg of body weight
50 and up	1.2g protein per Kg of body weight

If you are 35 years old, weighs 50kg, you will need 0.8 x 50 = 40g protein daily
If you are 65 years old, weighs 62kg, you will need 1.2 x 62 = 74.4g protein daily

The above calculation is for normal individuals with a healthy body weight. For those who are overweight or are highly active such as competetive atheletes, protein requirement will be different.
