A common dietary approach for weight loss that involves monitoring macronutrients is known as flexible dieting or the "If It Fits Your Macros" (IIFYM) method. This approach emphasizes tracking carbohydrates, proteins, and fats rather than focusing solely on calories. By adhering to specific macronutrient ratios, individuals can enjoy a variety of foods while still working towards their weight loss goals. This method promotes a sustainable lifestyle rather than a restrictive diet, allowing flexibility and reducing the likelihood of feelings of deprivation, making it easier to maintain long-term adherence.
