What Flexitarian Diet means
The term ‘flexitarian’ is a combination of ‘flexible’ and ‘vegetarian’. It describes an eating style that is predominantly plant-based but doesn’t completely eliminate meat. Unlike stricter diets, it has no firm rules about calorie counting or macronutrient ratios. Instead, the focus is on incorporating more plant foods like fruits, vegetables, legumes, and whole grains into your diet while reducing, but not forbidding, animal products. The core idea is to reap the benefits associated with vegetarian eating without requiring an all-or-nothing commitment, making it an approachable starting point for eating more plants.
The flexitarian approach has gained popularity as a more sustainable and less rigid alternative to traditional vegetarianism or veganism. It acknowledges that for some people, a gradual reduction in meat consumption is more achievable than complete elimination. This style of eating aligns with many traditional dietary patterns from around the world that naturally feature plants as the centerpiece of meals, with meat used more sparingly. It’s less of a formal diet and more of a lifestyle choice that prioritizes whole plant foods as the foundation of a nutritious eating pattern.
In daily life, being a flexitarian can look different for everyone. One person might follow a vegetarian diet during the week and eat meat on the weekends. Another might adopt a ‘Meatless Monday’ routine or simply decide to make meat a smaller component of their meals, rather than the main focus. This adaptability makes it easier to navigate social situations, such as dining out with friends or eating at family gatherings, where vegetarian options might be limited. The lack of strict rules allows individuals to adjust their intake based on their preferences, schedule, and social context.
While its flexibility is an advantage, the absence of clear guidelines can be a challenge for those who thrive on structure. The health benefits of a flexitarian diet depend entirely on the quality of the food choices made. A diet of highly processed plant-based foods and occasional fried chicken is technically flexitarian but lacks the nutritional benefits of one centered on whole foods. It is also necessary to be mindful of nutrients commonly found in meat, such as iron, vitamin B12, and zinc, and ensure they are being consumed from other sources.
What public guidance says
The American Heart Association recommends eating fish, particularly fatty fish, at least two times a week.
How to Try a Flexitarian Diet
- Start by incorporating one meatless day per week, then gradually add more as you get comfortable.
- Swap animal protein for plant-based protein in familiar recipes. For example, use lentils in bolognese sauce or black beans in tacos.
- Think of meat as a condiment or side dish rather than the main event. Fill the majority of your plate with vegetables, legumes, and whole grains.
- Explore new recipes from cuisines that are naturally rich in plant-based dishes, such as Mediterranean or Indian food.
- Focus on adding more whole foods to your diet, rather than just focusing on what to remove.

Common misconceptions
- Myth: You have to carefully track how much meat you eat. The flexitarian approach is about your overall eating pattern, not strict quotas. The goal is to reduce meat consumption gradually in a way that feels sustainable to you.
- Myth: It’s not a ‘real’ vegetarian diet. It isn’t intended to be. The term ‘flexitarian’ was created to describe a distinct eating style that is mostly vegetarian but intentionally includes flexibility.
- Myth: You won’t get enough protein. Many plant-based foods are excellent sources of protein, including lentils, beans, tofu, tempeh, nuts, and seeds. A well-planned flexitarian diet can easily provide adequate protein.
