Are you primarily interested in losing weight? Is eating healthier and maintaining your weight most important? Do you want to save money or make eco-friendly choices? Being clear about your goal "can help you align your values with a particular diet," Smith says. For instance, if you're interest in food sustainability, the Nordic diet promotes concern for protecting the environment and producing less waste. However, Nordic food recommendations could strain your budget if saving money is a key objective. "Consider which diet you can be most consistent with," Smith says. "While aiming for perfection is a recipe for doom, consistency is very important for success."
