The White House unveiled a mammoth proposal to reduce childhood obesity on Tuesday, with a 124-page report and 70 recommendations to slow what has become a health crisis among children. The goal? To get the nation’s childhood obesity rate from the current, staggering 20% down to 5% by 2030.

Among those recommendations, everything from a direct attack on the amount of junk food advertising aimed at kids, restaurant portion sizes and consideration of a sugar and fat tax, to ensuring that kids can safely bike and walk to school and play outdoors.
