The Flexitarian Diet, created by dietitian Dawn Jackson Blatner, offers a balanced approach to healthy eating by encouraging a primarily plant-based diet while allowing for moderate consumption of animal products. This makes it a more flexible option than strict vegetarian or vegan diets. If you're seeking to incorporate more plant-based foods into your diet without completely eliminating meat, the flexitarian approach may be a suitable choice.
What is the Flexitarian Diet?
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 diet's name is a combination of "flexible" and "vegetarian," reflecting its adaptable nature. While vegetarians exclude meat and sometimes other animal foods, and vegans avoid all animal-derived products, flexitarians include animal products in their diet, differentiating them from vegetarians and vegans.
The Flexitarian Diet lacks rigid rules or specific recommendations for calorie and macronutrient intake, making it more of a lifestyle choice than a strict diet. It revolves around these core principles:
- Prioritize fruits, vegetables, legumes, and whole grains.
- Emphasize plant-based protein sources over animal sources.
- Incorporate meat and animal products occasionally.
- Choose minimally processed, natural foods.
- Limit added sugar and sweets.
The Flexitarian Diet's adaptability and focus on inclusion rather than restriction make it an appealing option for those seeking a healthier eating pattern. While Jackson Blatner's book suggests specific meat consumption amounts per week, these recommendations are not mandatory. The primary objective is to increase the consumption of nutritious plant-based foods while reducing meat intake.
Health Benefits of the Flexitarian Diet
Adopting a flexitarian diet may offer various health advantages. Research on vegan and vegetarian diets can provide insights into the potential benefits of semi-vegetarian eating.

It's crucial to prioritize fruits, vegetables, legumes, whole grains, and minimally processed foods to maximize the health benefits of a plant-based diet. Merely reducing meat consumption while continuing to consume refined foods high in added sugar and salt will not yield the same positive outcomes.
- Heart Health: Diets abundant in fiber and healthy fats contribute to heart health. Studies reveal that fish eaters and vegetarians exhibit lower rates of ischemic heart disease compared to meat eaters. Vegetarian diets are often rich in fiber and antioxidants, which can lower blood pressure and improve cholesterol levels. A review of 15 studies demonstrated that vegetarian diets significantly reduced systolic and diastolic blood pressure compared to omnivorous diets. A study involving 10,797 participants found that individuals adhering to vegetarian, pescatarian, or flexitarian diets had lower body mass index, total cholesterol, and blood pressure compared to meat eaters.
- Weight Management: The flexitarian approach can aid in weight management due to the emphasis on lower-calorie plant foods and the limitation of high-calorie, processed foods. Studies suggest that individuals following plant-based diets tend to lose more weight than those who don't. A review of studies involving over 1,100 participants showed that vegetarian diets led to greater weight loss compared to non-vegetarian diets. While the Flexitarian Diet may support weight loss, its primary goal is to promote the consumption of nutrient-dense foods like fruits, legumes, and vegetables.
- Diabetes Prevention: A predominantly plant-based diet can help prevent and manage type 2 diabetes. Plant-based diets support weight loss and provide fiber-rich foods with low levels of unhealthy fats and added sugar. A study involving over 200,000 participants revealed that a diet emphasizing plant foods and limiting animal foods was associated with a reduced risk of diabetes. Healthy plant-based diets, including whole grains, fruits, vegetables, nuts, legumes, and vegetable oils, were linked to a greater decrease in diabetes risk.
- Cancer Risk Reduction: Diets rich in nutritious plant foods and low in ultra-processed foods are associated with a lower risk of certain cancers. Research suggests that vegetarian diets are associated with a lower overall incidence of all cancers, but especially colorectal cancers. A 7-year study involving 78,000 people found that semi-vegetarians were less likely to develop colorectal cancer compared to non-vegetarians.
Environmental Impact
The Flexitarian Diet benefits both individual health and the environment. Reducing meat consumption helps conserve natural resources by decreasing greenhouse gas emissions and land and water usage. Shifting from a typical Western diet to flexitarian eating, where plant foods partially replace meat, can decrease greenhouse gas emissions. Cultivating plants requires fewer resources than raising animals for consumption. Greenhouse gas emissions from vegan and ovo-lacto-vegetarian diets are significantly lower than those from omnivore diets, resulting in reduced natural resource use.
Potential Nutrient Deficiencies
While well-planned flexitarian and plant-based diets can be very healthy, some individuals may face nutrient deficiencies when reducing meat and animal product consumption. Potential deficiencies include:
- Vitamin B12
- Zinc
- Iron
- Calcium
- Omega-3 fatty acids
Vegetarians may be at risk for vitamin B12 deficiency, as it is naturally found only in animal products. However, B12-fortified foods and supplements can help address this deficiency. Flexitarians may also have lower stores of zinc and iron, which are best absorbed from animal foods. Vitamin C can enhance iron absorption from plant-based sources. Some flexitarians may need to focus on plant-based sources of calcium if they limit dairy intake. Plant foods rich in calcium include bok choy, kale, chard, and sesame seeds. Adequate intake of omega-3 fatty acids, typically found in fatty fish, is essential. Supplementation with algal oil or fish oil may be considered to maintain optimal EPA/DHA levels.
The flexibility of the Flexitarian Diet allows for varying consumption levels of meat and animal products. With careful planning and a diverse intake of whole foods, nutritional deficiencies can be minimized.
