The Flexitarian Diet Meal Plan: A Flexible Approach to Healthy Eating

The flexitarian diet is a marriage of two concepts: flexible and vegetarian. Also known as a semi-vegetarian diet, the flexitarian diet allows you to reap the health benefits associated with vegetarianism without giving up meat altogether. Instead, you can choose meatless meals most of the time, but still enjoy a burger or steak on special occasions. And because it reduces meat consumption, it’s considered planet-friendly.

What is the Flexitarian Diet?

A flexitarian diet is simply a mostly plant-based eating pattern that occasionally includes meat or other animal products. Calling it “semi‑vegetarian” is a good description. You focus on vegetables, whole grains, legumes, and the like, while still having room for meat and dairy in moderation. The Flexitarian Diet is a style of eating that encourages eating mostly plant-based foods while allowing meat and other animal products in moderation. It’s more flexible than fully vegetarian or vegan diets.

The term was coined more than a decade ago by registered dietitian Dawn Jackson Blatner in her 2009 book, "The Flexitarian Diet: The Mostly Vegetarian Way to Lose Weight, Be Healthier, Prevent Disease and Add Years to Your Life." Dawn Jackson Blatner, RDN CSSD, introduced this Semi-Vegetarian diet in her 2010 book, “The Flexitarian Diet”.

Principles of the Flexitarian Diet

The Flexitarian Diet has no clear-cut rules or recommended numbers of calories and macronutrients. In fact, it’s more of a lifestyle than a diet. It’s based on the following principles:

• Eat mostly fruits, vegetables, legumes, and whole grains.
• Focus on protein from plants instead of animals.
• Be flexible and incorporate meat and animal products from time to time.
• Eat the least processed, most natural forms of foods.
• Limit added sugar and sweets.

Flexibility is Key

Yes, considering “flexible” is part of its name, the flexitarian diet is highly flexible and adaptable, making it an easy diet to follow. As a result of its flexible nature and focus on what to include rather than what to restrict, the Flexitarian Diet is a popular choice for people looking to eat healthier. Some people following the diet may eat more animal products than others. Overall, the goal is to eat more nutritious plant foods and less meat.

"The focus is still: Eat more plants and be flexible instead of strict about it," Blatner says. "To be clear this is a ‘lifestyle,’ not a traditional ‘diet.’"

Why Choose a Flexitarian Diet?

If you’re looking to add more plant foods to your diet but don’t want to completely cut out meat, going flexitarian may be for you.

Health Benefits

By eating more plant foods and less meat, people who follow the diet may not only lose weight but can improve their overall health by lowering their rate of heart disease, diabetes and cancer. Eating flexitarian may provide several health benefits. The Flexitarian Diet may help manage weight and reduce the risk of heart disease, cancer, and type 2 diabetes.

• Promotes Heart Health: Plant-based diets, including the flexitarian diet, are associated with a lower risk of cardiovascular disease. Diets rich in fiber and healthy fats are good for heart health.A 2020 review of 15 studies found that a vegetarian diet significantly lowered systolic and diastolic blood pressure as compared to an omnivorous diet. Furthermore, a 2020 study on vegetarian, pescatarian, and flexitarian diets that included 10,797 participants found that those who adhered to any diet excluding/reducing meat intake had lower body mass index, total cholesterol, and blood pressure than those who ate meat.
• Reduces Inflammation: By increasing your intake of plants, you naturally increase your consumption of antioxidants that help to fight off inflammation in the body.
• Prevents and Manages Diabetes: Like other plant-based diets that emphasize eating less animal products, a flexitarian diet has been shown to be effective in preventing and managing Type 2 diabetes. A study with more than 200,000 participants found that a diet that emphasized plant foods and was low in animal foods was associated with about a 20% reduced risk of diabetes.
• Weight Management: Flexitarian eating may also help you manage your weight. This is partially because flexitarians often limit high calorie, highly processed foods and eat more plant foods that are naturally lower in calories. Several studies have shown that people who follow a plant-based diet may lose more weight than those who do not.

Environmental Benefits

The Flexitarian Diet may benefit your health and the environment. Reducing meat consumption can help preserve natural resources by decreasing greenhouse gas emissions and land and water use. Eating flexitarian and swapping meat for plant protein is good for the planet. Plant-based diets use fewer fossil fuels and less land and water.

Is a Flexitarian Diet Healthy?

Yes, it absolutely is. A flexitarian diet supports heart health, helps manage weight, and may reduce the risk of type 2 diabetes and certain cancers. In our experience, emphasizing plant sources while occasionally including lean meats or fish balances nutrients perfectly.

It’s also easier to sustain long-term than a fad or crash diet like the smoothie diet plan because it’s not all or nothing.

Can the Flexitarian Diet Help Me Lose Weight?

Yes, you'll likely shed pounds and maintain a healthy weight on the flexitarian diet in the long run, especially if you’re switching from the standard American diet and incorporating regular physical activity. In fact, a 2015 study that evaluated post-menopausal women over a 20-year period showed that participants who followed a flexitarian diet had significantly lower body mass index, body weight and body fat percentage than those who followed a non-vegetarian diet.

A 2022 study found that plant-based diets lead to short-term weight loss. One review of 25 different studies found that participants' body mass index was on average lower when they were following a semi-vegetarian diet than those who followed a non-vegetarian diet.

Who Should Not Follow the Flexitarian Diet?

The flexitarian diet is family friendly and can meet kids’ needs. However, pregnant people and those with diabetes or other chronic medical conditions should talk with their doctors before making major dietary changes.

Flexitarian Diet Tips and Advice

Shifting your eating habits takes more than a grocery list. The most successful flexitarian plans are built on small, realistic steps and a little curiosity in the kitchen. These tips are designed to make the transition easier, more enjoyable, and a lot more sustainable:

• Start with Meatless Mondays: One day a week is a great place to begin. By choosing Monday as your meatless day, you're creating a clear and predictable rhythm that’s easy to remember. Pick a favorite recipe like veggie tacos or a simple lentil curry and try it in place of a typical meat-based meal.
• Stock Smart: Pantry staples are your secret weapon. Keeping canned beans, brown rice, quinoa, pasta, nut butters, frozen vegetables, and a few spice blends in your kitchen makes it easier to build balanced, flavorful meals without a lot of prep.
• Think Long‑term, Not Perfect: Flexibility is the core of this approach. You don’t need to meet a quota of meatless meals each week or follow strict rules to benefit. What matters is consistency over time.
• Balance Nutrients Thoughtfully: When you eat fewer animal products, some nutrients need more attention. Protein can come from foods like tofu, lentils, eggs, Greek yogurt, or even edamame.
• Keep Exploring New Flavors: One of the best parts of a flexitarian meal plan is discovering new foods you genuinely enjoy. Experiment with seasonings from different cultures like turmeric, garam masala, za'atar, or smoked paprika.

Getting Started: A Practical Approach

How Do You Become a Flexitarian?

Start small. Adding one vegetarian meal a week (like Meatless Monday) is a powerful first step. Then build gradually. Keep your pantry stocked with beans, whole grains, spices, and frozen veggies to make plant-based meals feel easy. Finally, think of this as a journey, not a test. Flexibility is the goal, and it makes sticking to the plan more realistic.

Gradually reduce meat portions and increase meat-free days per week during each stage. To ease into it, you can start by adding plants to every meal to start - at least 2 cups per meal, equivalent to half of your plate. Select one meal a day that you can easily replace animal products with plants. For example, switch out eggs and sausages for oatmeal topped with chia seeds and berries for breakfast. For lunch, opt for a salad with beans instead of chicken.
