As an autistic person, professionally diagnosed, this sounds like nonsense woo. Yes, gut bio can influence moods and managing your health can improve symptoms from autism (e.g. meditation might help manage anxiety). But no amount of "don't eat bread" is going to help me understand faces or social cues. A good diet might help with self esteem, overall energy levels, and resilience to my symptoms (if I'm healthier, I shut down less). But that's it, it's not going to change the way I experience the world, just stretch my tolerance for it.
