Detox is not a cleanse but a genetic program built into human cells. Vitamin A is a master switch for immunity, tissue repair, inflammation control, and detox. Only animal foods provide ready-to-use retinol; plant carotenoids must be converted in the liver and many people do this poorly. Small weekly servings of liver maintain vitamin A reserves, supporting bile flow, detox enzymes, and the epithelial barriers of the gut, lungs, and skin that block toxins and germs.

Essential vitamins are essential because the human body cannot synthesize them in sufficient quantities to meet its needs. They are critical for numerous biological processes necessary for survival and optimal health. Without these vitamins, the body cannot perform vital functions, leading to deficiencies and associated health problems.

Dietary fat is far more than a source of calories. It helps build cell membranes, supports hormone production, protects organs, fuels the brain, and enables the absorption of vitamins A, D, E, and K. Essential fatty acids must come from the diet and are critical for health. On a ketogenic diet, fat becomes the body's primary fuel source, providing steady energy through fatty acids and ketones while supporting metabolic health and overall well-being.
