What Is A Flexitarian Diet?

Flexitarianism is the new buzzword in the world of plant-based diets. The term “flexitarian” is a combination of the words ‘flexible’ and ‘vegetarian,’ which means it is a more moderate and balanced approach to eating.

It is primarily a plant-based diet that allows for the occasional consumption of meat, fish, and dairy products for a healthy lifestyle. Basically, it emphasizes eating mostly fruits, vegetables, whole grains, legumes, and nuts. This type of diet is considered a more balanced approach to eating as it promotes the health benefits of a plant-based diet while also allowing for the inclusion of animal products for those who choose to consume them ( 1 ).

In recent years, the popularity of vegetarian diets has been on the rise. There are several reasons for this trend, including increasing awareness of the health benefits of plant-based diets, concerns about the environmental impact of meat production, and ethical concerns about the treatment of animals.

The diet also allows for a more gradual shift toward a plant-based and meatless diet for those who may not be ready to commit to an entirely vegetarian or vegan lifestyle. So, if you are an Omnivore, Carnitarian, or Pescatarian looking for a fish or meat reduction plan, this balanced diet might be suitable for you.

Overall, the flexitarian diet is a healthy and sustainable way of eating that can support overall health and well-being. The following section will explain how this diet works and how it can help you stay healthier.

Key Takeaways

• The flexitarian diet is a plant-based eating regimen that permits the occasional inclusion of meat.
• This diet’s objective is to lower overall meat consumption for environmental and health reasons.
• Compared to rigorous vegetarian or vegan diets, it is regarded as a more flexible and easy way of eating.

How Does A Flexitarian Diet Work?

A flexitarian diet is a more pragmatic approach to vegetarianism or veganism. It allows you to adjust the frequency of meat consumption according to your dietary needs and preferences. For instance, some people may eat meat 2-3 times a week, while others may consume meat only once a week.

It is crucial to understand that the flexitarian diet does not necessarily involve eating minimal meat, but rather it emphasizes plant-based foods while still allowing for the odd consumption of animal products. Due to this, it helps in reducing meat consumption and may help you move towards a meat-free lifestyle. Here are some tips to follow the diet effectively:

• Start by incorporating more plant-based and meat-alternative foods into your meals. Try to make these items the star of your meals, and use animal products as more of a side dish or a condiment.
• Make an effort to eat at least one vegetarian or vegan meal daily. This can be for lunch, dinner, or both. This is a fantastic method to increase your intake of plant-based foods without feeling too restricted.
• Pay attention to portion sizes. If you do decide to consume animal products, strive to limit your intake and make sure your diet is well-balanced with plant-based meals.
• Plan ahead. Making healthy decisions when traveling can be facilitated by planning your meals and snacks. This can be accomplished by carrying your own lunch, keeping nutritious snacks on hand, or cooking meals in advance.
• Be adaptive and open-minded. Don’t be too hard on yourself if you slip up or end up eating out something that is not 100% plant-based. After all, the flexitarian diet is all about flexibility.

The flexitarian diet is rich in fruits, vegetables, whole grains, legumes, and nuts, which are all nutrient-dense foods that provide essential vitamins and minerals. Studies have shown that vegetarians and vegans consume more folate, vitamin E, and magnesium compared to meat eaters. Vegans also consume more vitamins B1, B6, and C ( 2 ).

According to studies, adopting a vegetarian diet has proven to be more effective in reducing the symptoms of diabetes than conventional treatments. In comparison to a diet that included weekly meat eating, lifelong adherence to a vegetarian diet in a study was found related to a 74% lower risk of acquiring diabetes ( 6 ).

A lifelong commitment to a vegetarian diet has been linked to a 35% decreased chance of developing diabetes, according to research on non-smoking, non-drinking Buddhists. More importantly, compared to non-vegetarians, those who switched to a vegetarian diet after previously not doing so had a 53% decreased chance of developing diabetes ( 6 ).

A diet rich in fruits, vegetables, and whole grains has been linked to a reduced risk of certain cancers. According to studies, plant-based diets exert anti-inflammatory and antioxidative actions against the onset of cancer. It has also been shown to protect against digestive tract cancers ( 7 ), ( 8 ).

1. May Benefit The Environment

Eating a diet that is mostly plant-based can positively impact the environment by reducing the demand for meat and dairy products. Studies have demonstrated that compared to the majority of modern omnivorous diets, ovolactovegetarian, and vegan diets produce greenhouse gas emissions that are 50% and 35% lower, respectively, and consume correspondingly fewer natural resources ( 9 ).

1. May Aid In Weight Loss

Can you lose weight on a flexitarian diet? Research suggests, yes ( 1 ). The diet encourages a higher intake of plant-based foods like fruits, vegetables, and whole grains that are low in calories and rich in fiber. A high intake of fiber is associated with an increased feeling of fullness. This can prevent overeating and may help you manage obesity ( 10 ). Further, the diet also allows you to choose your meals according to your preferences. This way, you will be able to stick to it for a long time and achieve sustainable weight loss.

Cons

1. Offers Limited Options

Flexitarians may find it difficult to find suitable options when eating out, especially when traveling and in areas where meat-centric meals are the norm. This can make it more challenging to stick to the diet, especially if you eat out frequently.

Additionally, some social situations may involve peer pressure to eat meat or other animal products, which could make it difficult to stick to the diet. It requires you to explain your dietary choices to others, which can be time-consuming or uncomfortable.

A social stigma may be associated with being a “flexitarian” or “semi-vegetarian” in some circles. It could also be challenging for people to follow a flexitarian diet in cultures where meat consumption is a traditional and important part of the society.

1. May Lack Essential Nutrients

It may be challenging to get the right balance of nutrients for some people, especially if you are not used to planning your meals and find it difficult to keep track of your nutrient intake. A flexitarian diet may not provide enough of certain nutrients, such as iron, calcium, and vitamin B12, that are typically found in animal products. Studies have shown that vegetarians, and particularly vegans, consume less protein, iodine, EPA i Eicosapentaenoic acid; a type of omega-3 fatty acid obtained from fish oil that may help reduce cellular inflammation. , and DHA i Docosahexaenoic acid; a type of omega-3 fatty acid obtained from fish oil that aids in boosting brain health. on average than meat eaters ( 2 ).

1. May Promote Overindulge In Animal-Based Products

Since this diet is not strict, there is a potential for some individuals to consume more meat, fish, and dairy products than is recommended for optimal health.

It is important to note that these challenges can vary depending on your location and social circle, but with planning and communication, they can be manageable. This pressure can be greatly reduced by clearly understanding what you can and cannot eat when following this diet.

What Can You Eat On A Flexitarian Diet?

Focus on including healthy eating options like fruits, vegetables, whole grains, legumes, and nuts in your diet. This can include leafy greens, berries, whole wheat bread, lentils, and almonds. Additionally, you should restrict your consumption of meat, fish, and dairy products. When you do choose to consume them, pick lean, grass-fed, or sustainably produced options.

The flexitarian diet is slowly gaining popularity across the world. According to a study conducted on the Swiss population of 10,797 individuals, 15.6% claimed to follow the flexitarian diet ( 11 ).

Do flexitarians live longer?

Possibly. A study found that those who consumed meat less than weekly may increase their life expectancy by 3.6 years ( 12 ).

Is a flexitarian diet affordable?

Yes. A study showed that sustainable and healthy diets like the flexitarian diet are significantly cheaper than a regular diet ( 13 ).
