Individuals with PWS typically progress through 7 different nutritional phases during their lifetime.

In most cases it is the formulation more than the processing that results in foods that are not recommended as part of a healthy diet. Such \"ultra-formulated\" foods are unhealthy because they are high in added sugar and other caloric sweeteners, refined flours saturated fats and salt to increase palatability. The understanding that processing and formulation are distinct will assist health professionals in identifying the types of foods that are unhealthy and contribute to overconsumption and obesity.
