The Ornish diet is a low-fat, vegetarian diet with an emphasis on the inclusion of whole grains, beans, fruits, vegetables, (~70%-75% carbs), 15-25g fat (less than 10% of calories from fat), 15-20% protein. No animal products are allowed except egg whites and nonfat dairy products.
Remember, there is too much of anything. Even on a keto diet where fat is king, there is too much fat. It still has a lot of calories and if you have too many calories, you will still gain weight, even in ketosis. Also, as /u/crackills said, vegetables are overrated.
