As you move up the vertical line during the diet, the vertical diet suggests that you gradually boost the number of carbohydrates you take in. That is meant to represent your ascent toward optimal health and weight loss. On the vertical diet, you cannot consume foods high in raffinose. These foods, also known as gassy products, include broccoli and cauliflower. These foods consist of chicken, fish, brown rice, foods based on wheat, and dishes made with whole grains, beans and legumes, and brown rice.
