Thanks for your detailed reply but I think we'll have to agree to disagree on this.
That's OK, everyone is welcome to try what they wish.
I just urge caution. I would say the jury out on Keto at the moment, but that's not to say that it doesn't have some benefits. We ended-up in the 'Low Fat/high Carb' spiral because of some evangelist quoted some 'research' and sold his seemingly obvious story about fat making you fat, to the western world.... As it happens I never agreed with it then nor do I now - at the time I too was arguing against the tide of 'evidence'.
For every pro-something there is much 'evidence' for anti-something, people like to have agendas, Doctors, researchers et al are no different (Vaccines and Autism anyone?)*. There are evangelists on here and elsewherefor x,y,z that whilst enthusiastic, convincing and well-meaning are not qualified to promote or advise others** (antivaxxers on the interwebs) Hell I might be one too...
There is good research and poor research and anecdata. There are myriad conspiracy theories and I don't buy them either.
Right now I see no wider acceptance of Keto in any community/nation/pro-sport etc. suggesting this is method for improved health and life.
I would rather look at the big/global picture (a kind of meta-experiment) which I think tells an important story about diets, lifestyles and and health.
*For this I recommend the 'Angry Chef' and 'Bad Science'...
**I am not a Doctor, nor a Nutritionist (though my Daughter is). As a Food Technologist with a degree in Biochemistry with some 35 years of working in the global food R&D and industry, I have spent a lot of time watching ideas/trends/diets/hea;lth advice come and go, attended conferences and seminars on health/nutrition, followed eating and lifestyle trends, and now have to listen to my far more learned daughter. One soon starts to realise that many modern health issues are a western/first world illness caused by simple over-consumption of heavily processed food, foods high in simple sugars and empty calories and insufficient diversity of natural foodstuffs and fibres. Restrictive diets in any shape are form are not the answer either (and that includes veganism - shock horror).
Good luck, report back.
