A low-carb diet is very different from a keto diet. Although both seek to cut back on carbs, keto diets are far stricter. This means that a lot of non-keto foods are allowed in low-carb diets - and brown rice is one of them. So, if you think a low-carb diet is a better option for you than a full-on keto diet, then switching to low-carb will allow you to introduce brown rice to your diet. White rice, however, is still banned.
