Is My Kitchen Rules real?

Could you possibly enlighten me about the authenticity of "My Kitchen Rules"? Is it truly a show where participants engage in real-life cooking challenges, or is it merely staged and scripted for television entertainment? Do the participants truly compete with each other for culinary supremacy, or are the outcomes predetermined by producers? Are the emotions and interactions among the contestants genuine, or are they manufactured for the camera? I'm genuinely curious about the show's legitimacy and whether it offers a realistic portrayal of cooking competitions or if it's more of a heavily edited reality TV spectacle.
