Detoxing is nonsense, it's a complete fallacy that the body needs to detox. Removal of waste products and toxins is a continuous process and we don't need to periodically flush them out. The body does a perfectly good job of eliminating any substances on its own. The entire concept of needing to detoxify, purify, or cleanse your body with these regimes is literally made up by the diet industry to sell us more shit (that doesn't work) to fix our bodies (that don't need fixing).
