MY COMPLEX NETWORKS PROJECT
HOW EVERYTHING STARTED? 
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?
NICHOLAS A. CHRISTAKIS 
The Spread of Obesity in a Large Social Network over 32 Years
If the obesity spreads through network, the same thing can be 
observed with #fitness and #eatclean behaviors?
• A special attention must be given to the word 
behavior because the fact of people posting 
something doesn’t mean that he is doing what he 
is saying that he is doing. 
• I don’t have the body mass measurements of the 
users of twitter.
WHAT DO I HAVE? 
• Tweets with the hashtags #eatclean and #fitness 
• Users and followers of the users 
• Followers that also posted a tweet with the 
hashtags #eatclean and #fitness

Tweets: 
522188

Users:

DEFINITION OF THE NETWORK:
