Maintaining a healthy diet, not smoking, and moving around frequently are the cornerstones of health, but Americans are incrediby confused about how to eat a healthy diet, no matter how often we list and re-list "whole grains, fruits, and vegetables" and "avoid sugar." In fact, many foods not listed here--including fatty seafood, beef liver, olive oil, and bone marrow--are all "superfoods." The Mediterranean diet is heavy on olive oil, and research shows that is the key ingredient. Eating lots of fat, including animal fats, is a much better source of fuel than carbs because in reality, people who eat grain-based diets aren't gnoshing on brown rice all day. They are eating a lot of refined carbs and added sugars. But every framework for diet pushes lean meats, whole grains, etc. General healthy guidelines do not, in fact, exist--at least not in a meaningful way. The USDA Dietary Guidelines are vague and misleading and push carbs. They continue to, wrongly, vilify red meat and saturated fat.

It's heartening to see this article pointing out that how much we eat is critical, but so is how often we eat. High carb diets that rely on grains, fruits, and vegetables--the status quo--make frequent meals and snacks inevitable. Such diets induce hunger.
