I really can't say it enough
Your entire body runs on nutrients.
Each cell runs on nutrients.
The cells are surrounded by a bilipid layer aka two layers made up of fat. Fat that you need to consume because it is an essential nutrient (high quality fat that is).
Each of those cells make up tissues and the tissues make up organs. Which is all made possible by the nutrients you consume.
Those organs they make up systems. Your digestive system, your skeletal system, endocrine system, immune system, and so on. All of this is made possible BECAUSE OF NUTRIENTS.
Now those systems, in combination, make up us - the organism. And guess what? We. Run. On. Nutrients.
Which we get through what we consume and MORE IMPORTANTLY what we absorb.
Let that sit with you.
This is why I preach whole food, high quality, nutrient dense. It is the best fuel to run your body.
Vegetables, grass-fed/humanely sourced meat, eggs, good quality fat. I am even cool with grains, beans, and nuts that have been properly prepared aka soaked or sprouted or fermented.
It is worth noting when solving for nutrient density and what the body actually absorbs well - grains are not the best choice. Organ meats and herbs, however, they stack high up there!
You need decent nutrition to run your body.
And water, you need that too.
