We see a family during barbecue/breakfast/festivities.

Thoses families have a great time together while eating fresh products from Lidl

The voice over tells us "choose the fresh products from Lidl right now, because later you'll be on all-in-Hollidays/Ski hollidays... and this kind of thing means..."

at this moment, one of the character in the family starts to imagine the world of junk food. The craziest moments when their stomachs guide them into hell.

the middle part is a metaphor of our bad behaviours concerning the junk food.

Then we go back to the family moment, and the character who were in its thoughts, serve a lot of healthy fresh product to his/her family.
