Unlike bodybuilding competitions, fitness and bikini competitions focus more on overall shape, symmetry, and conditioning instead of muscularity and extreme leanness. Female bikini competitions typically consist of a swimsuit (model posing) routine whereas fitness competitions consist of both an athletic and posing routines. With that said, the foods that you put into your body can play a tremendous role in how you look onstage and stand up against your competitors. The components of a plant-based diet should include high-quality protein from plants, limited simple carbohydrates, low-sodium foods, fresh fruits and vegetables, high-protein carbohydrates, and fiber.
