Obesity / Overweight: Obesity, is caused by excessive intake of carbs, such as those present in rice and by our modern life style where activity has been engineered out of daily life, while we eat larger portions of calorie dense processed foods. The body stores unused calories as fat cells. Men and women store excess fat in different places, giving them curves in different locations.
