Nutrition Basics

What Do We Need to Survive a Day?

Beyond complex diets and supplements, what are the absolute non-negotiables your body needs to stay alive and function? Understanding these basics is the first step to mastering your health.

The Hierarchy of Survival

1. Oxygen (The Immediate Need)

You can survive weeks without food, days without water, but only minutes without oxygen. Proper breathing regulates stress and energy.

2. Water (The Solvent of Life)

Your body is 60% water. It transports nutrients, regulates temperature, and lubricates joints. Minimum 2-3 liters/day for basic function.

3. Energy (Calories)

Your Basal Metabolic Rate (BMR) is the energy cost of keeping your heart beating and organs working. Typically 1200-1800 calories/day just to exist.

4. Essential Nutrients (The Building Blocks)

Proteins (Amino acids) for repair. Fats (Fatty acids) for hormones/brain. Vitamins & Minerals for chemical reactions.

5. Sleep (The Restoration)

Sleep clears metabolic waste from the brain (lymphatic system). Without it, you hallucinate, lose cognitive function, and eventually die.

Thriving vs Surviving

Most people are just surviving—dealing with low energy, brain fog, and poor digestion. To thrive, you need:

Sunlight

Vitamin D & Circadian Rhythm

Movement

Lymphatic drainage & Heart health

Purpose

Mental health & Dopamine
