Gut feeling. Gut instinct. Spill your guts. What about: eat well for a healthy gut? In our everyday expressions, we attribute lots of things to the gut. But expressions aside, our guts are actually a very important part of our overall health and wellbeing. Over the past decade, researchers discovered connections between the gut—also known as the gastrointestinal tract—and a whole host of physical processes.

Several exciting studies even connect gut health to obesity. So how exactly do you restore and maintain a healthy gut? What are the most beneficial gut-healthy foods? And how does this all connect to your weight?
