Concept

We do not have to starve ourselves to lose weight, this is one of the most common misconceptions people have when trying to lose weight. The key is to eat a balanced diet. Our bodies require foods from each of the nutrition groups to maintain a healthy state. Some diet methods may asked you to eliminate food from certain nutrition groups from your meal and only focus on a few of them. This might works, but our body requires vitamins, minerals, fats, carbs, and protein to maintain a healthy lifestyle in the long run. Completely cutting out any groups can have damaging and harmful effects on our body.

The lack of awareness among many led us to the idea of using ambient display to encourage people to eat a balanced diet appropriate to their activity level of each day.

How It Works?

The ambient display is divided into three parts which represent portions of proteins, whole grains and fruits & vegetables. Each part lights up in a different color. This ambient display is linked to the users Google calendar which has their schedule including their exercise plan. The food proportion depends on the physical activity planned and noted in the Google calendar for each day. This ambient display can be positioned by the user in any part of the house be it kitchen or bedroom.
