Hardly “nothing else”. Two smoothies a day with 150g of oats blended in them will basically cover this. You’d still have plenty of room for other food.

But that's not what the study tested. The study showed that both calorie restriction, and calorie restriction combined with almost all calories from oats, reduced cholesterol; but that the effect was more durable for the latter case. No data was gathered on eating oats without calorie restriction in this study.
