The National Institute for Health and Care Excellence (NICE) has lowered the body mass index (BMI) measurement threshold for British Asians and said that along with other ethnic groups, they have a greater risk of diseases such as diabetes and should be careful about their weight.
The much stricter target has brought the UK in line with recommendations given by the Indian and World Health Organization.
The new threshold stipulates that a 5ft 11in (1.8m) Asian man should weigh below 75kg, whereas an Asian woman measuring 5ft 3in should weigh less than 59kg.
Until now, experts said that all UK adults should target a BMI of no more than 25 to be healthy but NICE said that isn't right for certain ethnic groups.
The new guidelines say that Asian people should aim for a BMI lower than 23.
