Macro partitioning
Trans fats are harmful and should be eliminated, while saturated fat's impact depends on the food matrix and what it replaces.
Eliminate trans fats completely. For saturated fats, focus on the food source (e.g., cheese, nuts) rather than just the fat content, and ensure you are replacing them with unsaturated fats, not refined carbs.
