Diet soda is a toxic cocktail of artificial sweeteners, preservatives, and flavor enhancers. You're not quenching thirst, you're poisoning your body. Real hydration comes from water, not a lab-made concoction.
Why trash
No calories, but artificial sweeteners trick your brain and may disrupt gut bacteria.
Try instead
Sparkling water with lemon, or seltzer water with a squeeze of fresh lime.
