The Atkins® diet started out as a fad, but quickly became a counter-mainstream movement that reset people's understanding of nutrition and weight loss, and their link to health.
They wanted to redesign the entire food, water and exercise tracking app that a person does every day.
The complexity of the system was that all the information could come from options preloaded by Atkins® or options created by the user. Therefore, it should be created for the module creating, editing, reading and deleting actions (traditional CRUD), always looking for the flow to be simple and self-explanatory.
