Weight loss/maintenance/gain is a simple equation of calories in versus calories out. And Brown rice is, in fact, a really health grain and unlikely to put weight on you. Further, it has lots of fiber to help regulate your BM's and keep you full longer. I know it can be scary to venture and try new foods in your diet, but you will not gain weight unless what you take in exceeds output. In fact, I recently read an excellent book about sports nutrition/feeding your body. In the book, the author (a renowned RD who trains professional athletes) spoke of the importance of carbs, esp for active individuals. Brown rice is an excellent source of nutrients, vitamins, and energy for your body!
