Meal planning and prep contribute to healthier eating by promoting more intentional food choices and portion control. When individuals take the time to plan meals, they are more likely to make nutrient-dense choices rather than relying on convenience foods that may be higher in calories and lower in nutrients. Preparing meals in advance helps to avoid impulsive eating and encourages adherence to dietary goals. Additionally, meal prep allows for better tracking of caloric intake and macronutrient distribution, improving overall dietary adherence.
