The long-standing weight loss rule of avoiding food after 6 PM is under scientific scrutiny. Many people follow this practice believing it prevents weight gain and promotes health. However, research suggests that the total caloric intake throughout the day is more significant than the specific timing of the last meal. The body continues to process energy and maintain metabolic functions regardless of the hour. While some find success with time-restricted eating, it is not a universal requirement for weight loss. Experts emphasize that nutritional quality and overall balance are the primary drivers of health. Consequently, the strict 6 PM cutoff is often viewed more as a habit than a biological necessity.
