Plant-Based Eating Habits That Stick

What exactly is a plant-based diet? See my simple definition.

I’m Keith A. Herman. I help people who are new to plant-based eating, or struggling with it, turn what they know into what they do every day.

I’m also the founder of the Expert Diet Project, an evidence-based initiative focused on correcting health misinformation by spotlighting the advice of the experts. The Expert Diet Project reflects the ideas and research in Eat Like an Expert, the Health & Well-Being Journal, and the Eat Like an Expert Newsletter.

What exactly is a plant-based diet?

Eating more plant foods may be the single most important step for improving your health and obtaining a healthy body weight. Plant foods include fruits, vegetables, legumes (beans, peas, and lentils), whole grains, nuts, and seeds. Eating an abundant amount of these foods is sometimes called a plant-based diet, plant-predominant diet, or plant-strong diet. There are many types of plant-based diets, including vegetarian, pescatarian, flexitarian, vegan, Mediterranean, DASH, Portfolio, MIND, and Nordic.

Any dietary pattern where a primary focus is consuming sufficient plant foods can be considered a plant-based diet. What is considered a sufficient amount is debatable, but from my research it is at least two and a half pounds each day. With a plant-based diet, most of the food on your plate are plants, as opposed to animal food or ultra-processed food. Most healthy eating guidelines now recommend a plant-based diet, including the World Cancer Research Fund, the American Heart Association, the Dietary Guidelines for Americans, the American Diabetes Association, the World Health Organization, the Global Council on Brain Health, and the EAT-Lancet Commission.
