I can share three things:

1. Eating everything raw

All edible animals, vegetables and minerals are incredibly good for us as they are... eat them all raw, uncooked and unmolested by being processed into crap foods that industrial companies try to sell us and make huge profits by extracting daily slices of your health (isn't it interesting that real, organic foods from nature with nothing added to them cost so much more than the crap pesticide and hormone added foods with a lot of other crap ingredients and processing along the way... and how is that possible that so much added production expense could end up costing us less? Simple: it ain't real food!).

2. Fast

Eat only what's stored on your body (your body will digest your own stored fat for energy and perfect nutrition while you're fasting). Fasting means you only get to drink pure water and breathe in clean air for however long you fast. There are too many reasons to cite here why fasting is so good for you, but you can find plenty of sources or even get Stephen Harrod Buhner's book @The Transformational Power of Fasting: The Way to Spiritual, Physical, and Emotional Rejuvenation: Stephen Harrod Buhner: 9781594774669: Amazon.com: Books to help you understand how, when and why to fast.

3. Cultivate Intention by Daily Practice
Intention is the key to mastery. As in, calling your shots and hitting them.
The problem with most improvement seekers in life is that they really don't know what they're looking for, and then they keep casting about capriciously for the next new thing. Maybe it's a feel-good journey, or a step towards fear – it doesn't matter why, but this simply doesn't work dependably unless you get lucky. The reason is that knowing what you're looking for is a developmental process that takes deliberate, methodical and focused practice – daily. So if you're constantly changing interests, scenery and thoughts about what you're doing, you're never going to discover your own internal progress of physical/emotional growth as driving enduring achievements by having the clarity of a stable baseline of meeting one thing, over and over again. So pick one thing and become progressively committed to mastering it. It doesn't matter what it is, anything will do... as long as you do.
