My bestest friend is Asian and her dad went on a low carb diet and lost 40 lbs. Her grandfather died during open-heart surgery. I have an Asian student whose mom always comments on my weightloss and told me that she just can't give up her noodles and rice. She is not obese but I can see where she might want to lose 20 lbs. Samarai wrestlers are mostly Asian ( I saw one who was Black ) and their diet is largely of carbohydrates. Keep in mind that Asians also have a higher risk of osteoporosis. So portion size and choice of carbs makes a huge difference.
