I think FMD is a much better solution than surgery, definitely safer, cheaper. I generally avoid meats, cheeses, and high-protein food while on FMD and eat 100% vegetarian (not vegan, at least not yet). I enjoy soup and hot meals, so I like to have one bowl of soup per day. Avocados have the sourge of going bad so it's best to pick them up more often than stock up for the week.
It's funny seeing this article about them trying to find drugs to regenerate beta cells:

(same story seen here on d-co-uk), trying to find drugs that induce beta cell replication instead of neogenesis seems less ideal. I've tried a lot of supposed beta cell regen drugs and none of them worked, at least not for extended periods, expept perhaps GLP-1 but there are other explanations as to how that's helped me (by slowing digestion and suppressing glucagon release from the alpha cells). But I think FMD is better.
Like I said before, for impaired beta cell function, it's obvious now that it's better to purge dead / stressed cells and replace them with brand new ones, through beta cell regeneration (neogenesis) rather than replication, which risks being stymied by various factors. Who knows, both things are probably happening, but the big thing that FMD promises is a way for the immune system itself to be rebooted. And if that happens, there's no reason why beta cells shouldn't thrive once again. Remove the cause of the disease and the symptoms should go away. I.e. type 1 is reversible (in theory).
We do know that type 2 is reversible through diet in many cases, but if FMD provides an easier way to achieve it, then I definitely wish you the best of luck. If it catches on because it's only a one time thing (or maybe once every few months), then that's great. Many people simply can't achieve weight loss that easily. I have always found it extremely hard, given that I take insulin shots every day, but cutting my insulin TDD has already reaped dividends for me, especially during FMD.
