Maintaining a food diary can significantly assist in healthier eating habits by promoting mindfulness and accountability. Writing down meals encourages individuals to reflect on their food choices, making them more aware of portion sizes and nutritional content. This practice can reveal patterns of overeating or reliance on unhealthy snacks. A food diary also serves as a tracking tool, helping individuals identify triggers for unhealthy eating and monitor improvements over time. Overall, it aids in setting and achieving nutritional goals by fostering better decision-making regarding food.
