family did any post mortem?

confirm heart blocked?

was he overweight?

First thing is consult doctor.

Change diet - nasi lemak, roti canai, fried food, mutton, beef curry, french fries, all this is no good. Eat once a month small portion is ok but if can stretch longer, even better.

If cannot tahan, cut back amount eg from daily, to alternate, to once a week & slowly switch to eating healthier choice.

Start with daily walking if possible, park further walk a bit more.

Ex colleague improve BMI by walking up stairs, 1st 1 floor, then 2, then >10 storeys. Slim down a lot.

Eat oats to reduce cholesterol. Add fruits to make it tasty.

Taste bud can adjust. Used to like tea with sugar, then tea w/o sugar, now tea also hardly drink.

Used to like oil + oyster sauce in vege. After some time, now just boil most of vege. Salt & kicap also don't put.

Salad avoid mayo or thousand island if possible. Slowly use less sauce.

Get enough sleep.
