Trying to eat more plants? Follow a flexitarian diet

Jan. 7, 2020 NBC News

Hands down, one of the best things you can do for your health (and the health of the planet) this year is to adopt a plant-focused diet. A flexitarian eating pattern emphasizes plant foods, such as veggies, fruits, nuts, seeds, pulses (beans and legumes) and whole grains, but leaves some room for meat, dairy and other animal foods. According to the latest U.S. News & World Report Best Diet Rankings, this eating pattern, specifically the one outlined in the book “The Flexitarian Diet” by registered dietitian nutritionist, Dawn Jackson Blatner, came in second healthiest overall and was considered among the easiest to follow. If you’re actively looking for ways to eat more plants and limit your meat consumption, adopting a flexitarian way of eating is a great way to go. Here’s what you need to know before you get started.

What are the health benefits of the flexitarian diet?

When you boost your intake of plant foods and reduce your intake of red and processed meats and other less healthful foods, such as heavily processed snack foods, refined grains and sweets, you’ll experience some major perks. Studies have linked a dietary pattern rich in wholesome, minimally processed plant foods with:

  • Keeping your mind sharp and preserving your memory over time
  • Improvements in body composition and weight management
  • Lowering the risk of challenging diseases, like type 2 diabetes and heart disease
  • A more positive outlook with greater creativity and deeper life satisfaction
  • Enabling you to live longer and enjoy a better quality of life as you age

You’ll get these benefits because plant foods provide the vitamins, minerals, fiber, antioxidants and polyphenols that protect your body and brain from a number of triggers that accelerate disease, aging and mood disorders. More and more, research shows that markers of health improve when you eat more plants and less meat.

I also can’t ignore that these same foods offer environmental advantages as well. Production of meat and dairy foods can drain our natural resources and these foods have a higher carbon footprint compared to plant foods. This means they contribute to climate change, which is hurting our planet and putting people at risk of food insecurity.

What else can I expect when following a flexitarian diet plan?

If you’re used to eating a lot of heavily processed foods, you might notice you fill up better on a flexitarian diet, which limits these foods and prioritizes fiber-rich veggies, fruits, pulses and whole grains. This can translate into other benefits as well. For example, feeling more satisfied with meals might mean you’re less distracted by hunger so you may be more productive at work or at home.

If you’re limiting heavily processed foods and favoring plant foods, you may also find you feel more energetic during the day and you sleep better at night. Proper sleep can have far-reaching benefits, including being less susceptible to the common cold.

All of this means that by adopting a flexitarian diet, you’ll experience some immediate benefits as well as some longer-term perks.

Are there any downsides to the flexitarian diet?

If you’re not used to eating a largely plant-based diet, you’ll need to adjust to trying new foods and limiting the ones that might currently be eaten on repeat. In Blathner’s book, “The Flexitarian Diet”, she guides newbies through making changes in a phased fashion.

If you’re currently existing on a lot of processed convenience foods, you may also have to get used to planning, prepping and cooking more than you’d like, so there could be some lifestyle adjustments to make. However, as I said earlier, this semi-vegetarian eating pattern is considered one of the easiest to follow so these drawbacks aren’t huge deterrents. And once you get used to the changes, they’ll become second nature.

You might also need to plan your diet more wisely to get certain nutrients or you may need supplements to fill in any gaps. For example, vitamin B12 and calcium are easier to come by in animal foods than plant-based ones, so you’ll need to make sure you’re still getting adequate amounts. Fortified plant-based milks and fortified whole-grain cereals can help on this front. Also, since this diet doesn’t eliminate animal foods entirely, you can still get important nutrients from them, and the truth is, by consuming more plants and adopting a flexitarian diet, you’ll boost your overall diet quality.

How much meat can I eat?

There aren’t any strict rules to follow, but in her book, Blatner offers some easy guidelines, depending on how much meat you’re currently eating. If you’re just starting out, Blatner suggests two meatless meals per week, however even when consuming meat, plant foods form the foundation of meals. Ultimately, “The Flexitarian Diet” book offers ideas on advancing the number of meatless meals you eat each week, but in truth, a flexitarian diet is by definition, flexible, so you don’t have to follow specific rules. Even if you don’t go meatless for a set number of meals, the idea is to eat smaller portions of animal-based meals, enjoy them less often, and make plant-based foods the center of your plate. With this philosophy, meat might be an accent or sized like a side dish rather than the main event.
