That is true but don't forgot that Indians have genetic predisposition to become obese too. Indians are more prone to insulin resistance and diabetes than anyone else.

And guess what's the leading causes of death for humans? Heart diseases

Research have shown that Indians have genetic predisposition to insulin resistance.

It’s very well studied and have many articles. You can google it.

A multiethnic cohort of 59,824 subjects living in Ontario, Canada found that, for the equivalent incidence of diabetes at a BMI of 30 kg/m2 in white subjects, the BMI was 24 kg/m2 in South Asians and 25 kg/m2 in Chinese subjects. The study concluded that Chinese subjects developed diabetes at a higher rate, at an earlier age, and at lower ranges of BMI compared with Caucasians

Interesting. I've always assumed the high rate of cardiovascular diseases amongst South Asians (Indians) are mainly attributed to their high insulin resistance. I guess I made the correlation wrongly.

I do know that Indians have always high rate of cardiovascular diseases. Perhaps it is solely due to their diet? Or probably there's something else that I'm not aware of. It's likely a combination of multiple things though.
