Have you ever resolved to eat healthier, only to be tempted by fast food options everywhere you look? Do you think you would exercise more if only you didn’t have to spend so much time in your car?
Many in the public health community think that factors like these play a big role in what we eat, how much we move, and what we weigh. And many communities have tried to change these factors through so-called “environmental interventions.”

About half of these studies focused on diet.
They found that studies involving mandatory changes to the food environment—such as laws banning trans fat in restaurants or requiring healthier foods to be offered in schools—were effective in their intended outcomes.
