Alternatives to rice are still carbs, even though you can try something that is higher in fiber like quinoa or barley. Those are very filling, and you won’t be tempted to eat so much of it.
On the other hand: if you really enjoy rice so much, try a recipe that combines rice with some variety of bean. It is a very traditional diet in many countries because the combination of rice and beans provides you with complete potein. This alters the ratio between carbs and protein and won’t leave you salivating for what you really would like to eat: rice.
That way you can have your rice and eat it, too 🙂
