MY COMPLEX NETWORKS PROJECT

Observation of my friend’s behavior related to food choices

Observation of the summer camp obese teenagers

Why people become fat?

• Genetics

• Money

• Friends

Is it a choice?

What makes people eat what they eat?

Why some people say that they want to lose fat but still having the same habits related to food even knowing about nutrition and knowing that they shouldn’t eat what they are eating?

HOW EVERYTHING STARTED?
