The concept of energy density of the University of Munich is a scientificly proven and established approach for loosing weight.

It suggests alternatives for high calorific food ("red food") so that you can maintain your lifestyle but eat the alternative that fits to your goal to loose weight.

Killer app for lifesum: When you go shopping check the products if they are "green" (not high calorific) via scanner, if not get a suggestion what could be an alternative that helps you to loose weight.

The approach combines the idea that you need something in your stomach with the psychology behind eating.

It establishs a traffic light system for food: Green = you can eat as much as you want, yellow = be careful, red = do not eat that.

For red/ yellow food alternatives are suggested, e.g. instead of "viennese schnitzel with french fries" take "schnitzel without breadcrum coating and fried from the oven". (I am from Germany ;) )

I really like this approach and would be enthusiatic to see it integrated into lifesum!
