If any of those happened, wouldn't the entire world see those physiological effects? Being a bit more realistic is the hawthorne effect, which can be easy to test with follow up experiments. My biggest takeaway isn't to do IF or cut calories, but rather it seems some phenomena was found. If you asked me if diet, fasting, etc... Would cute cancer, I'd have said NO! but this study has changed that answer to "I don't know". I suggest that is a huge difference and benefit.
