No, there definitely seems to be a "there" there. I went zero carb for 6 months and I was able to continually fast for 24-44 hours at a time, always with zero hunger pangs after the initial "break-in" period, which seems to be about 2-3 weeks. Sadly I don't think the zero carb life is "doable" for me personally, because giving up pasta and pizza is a huge ask. Honestly I would rather die 10 years earlier than live a life with no pizza or carbonara.
