Thanks for the research and the sharing of info and experiences. Much appreciated!

I should add: My experience with the keto diet was using just one version of it. It was on the "medical" (serious) level and supervised by a physician/reseracher.
Even so, there are different versons of the Keto lifestyle.

It may help to recall that the keto diet was first used for the treatment of epilpesy. (Oh No! I could go on about Oliver Sacks, M.D. and the potential relationship between: epilepsy, migraine and BP.. I won't..)

Please know you can add fiber if you cannot get enough veggies.
There is a list of things which help:
Fiber
water
oils (healthy)
exercise

If needed: magnesium citrate (caps/pills/liquid), docusate sodium (stool softener) Some people need MIralax: others find it too stimulating.

If more antioxidants are needed,and you have a fruit/veggie restricted diet, you may add antioxidants via supplementation. A diet this restricted should probably be time-limited.

I think the mediterranean diet is likely the most healthy, with oils and antioxidants, enzymes, fiber and expansive energies.. I have not been able to lose weight on it, however. I might be able to make some adjustments and make it work.

I like the Paleo diet, as well. I have been able to lose weight with this diet.

Yet, I feel the veggies and fruits have more expansive energies, which is much more appealing to me than an overloaded diet of foods with contracted energies.
What to do,? Time wil tell!
Thanks, everyone!
