The concept involves preparing meals in advance, typically for several days, with detailed nutritional information, including macronutrient breakdowns. For example, a pre-portioned lunch might include grilled chicken breast, brown rice, and steamed broccoli, with calculated protein, carbohydrate, and fat content readily available.
This approach facilitates adherence to dietary goals, improves portion control, and saves time. Its relevance has grown alongside increasing awareness of the impact of diet on health and fitness. Historically, planned food preparation was common for practical reasons; now, it is employed strategically for optimizing nutrition.
