Arnold Schwarzenegger has introduced a "Zero Negativity Diet" for 2026, focusing on mental well-being rather than physical weight loss. The initiative encourages a one-week detox from negative thoughts, toxic self-talk, and criticism of others. Schwarzenegger emphasizes that negativity can be detrimental to both emotional and physical health, citing studies on optimism and longevity. The program suggests limiting social media, reframing problems, and practicing gratitude to build resilience.
