Brown fat, the bad kind

Unless you have been hiding under a rock you know that people of South Asian are at more risk for metabolic disease than is the norm. More concretely we tend toward “skinny fat.”

My current BMI 24. By normal calculators I’m normal weight (barely), because the cut-off is 25. But for South Asian we should be worried if we’re above 23.

There is the caveat that muscle is heavier, so one shouldn’t take BMI literally, as opposed to seriously. You know if you have too much visceral fat, you don’t need to weight yourself. The phenomenon of brown guys with big bellies due to years of self-indulgence is a thing. And excess weight among South Asians who reach a certain affluence level seems a thing the world over.

So here’s a question: for those of you who have managed to keep the weight off and stay trim, how do you do it? Exercise? Diet? Both?
