This is only a brief guide about what I gathered. To deeper knowledge of why I am saying this all, you'll'ave to research on your own. This practices are designed to outcast most defficiencies known by wizkids away (muh brainfog, restlessness, etc), exceptuating only those given by genome:

>leave all diaries, inmediately
>leave grains: no wheat, corn or rice at all
>eat your foods within a reduced schedule, rather than through all the day long
>avoid starchy foods and red meats
>if not vegetarian, eat meats briefly: like once a week or two weeks
>the softest and wealthiest meats are white fish
>do you like nuts? They are still acidifiers...
>learn your ayurveda body type (dosha) and how to regulate it

If you want quick results, these are the shock therapies:
>fasting regularly (the body must slowly develop its ability to detox or adversities a.k.a "detox crisis" are to be faced. The same on mucusless diet.)
>colon enema
>HIIT exercise
>do not use domestic cooling/heating unless your body strictly requires so, due to some sickness or whatever else
>drink hot water, as much as it can be without harming your mouth
>use temazcalli
>try (your body may not be done for so, so just try) keto diet

To further understand it all, next readings are recommended (or immediately needed depending on your degree of harm):
>every single book from Arnold Ehret
>"The Tao of Health, Sex and Longevity" by Dan Reid
>"Healing by Fasting" by Alexi Suvorin
>"The Power of Metabolism" by Frank Suarez
>"Grain Brain" by David Perlmutter
>"How I became young at sixty" by Horace Fletcher
>"Longevity diet" by Walter Longo
>"The cheese trap" by Neal Barnard
>"The Salt Fix" by James Nicolantonio
>"One meal a day" by Yoshinori Nagumo
>some books about specific organ cleansing by Andreas Moritz (the other ones I don't trust them much = up to you)
>"Lies my doctor told me" by Ken D. Berry
>"Flax oil as true aid against ..." by Johanna Budwig
>"Lymphatic lessons" by Kelly Kennedy
>"The body has its reasons" by Therese Bertherat
>"The Wim Hof method" by Wim Hof

Synthetizing common ideas withhold by all these tomes you should have what school didn't taught about the easiest forms of medicine, enough to keep most chronic diseases at bay. It may require patience and alertness in order to avoid the lethal effects of sudden, uncontrolled detox crisis.
