I would also gain weight eating these things you describe. Do you eat greens, juicy fruit? Dates, rice, oatmeal, potatoes and bananas give me a stomach ache just reading it. The concept states to eat as much juicy fruit we want till 4:00pm. I would be sluggish and not at my best eating these things. Try to explore into citrus, mango, berries etc, and include tons of greens, celery, cucumbers.
