Should you be a flexitarian?
By Jennifer Nelson, M.S., R.D. and Katherine Zeratsky, R.D.
The recently released 2010 Dietary Guidelines for Americans urge Americans to eat a plant-based diet. Plant-based diets have many health benefits. With their emphasis on fruits and vegetables, grains, beans and legumes and nuts, this way of eating is rich in fiber, vitamins and other nutrients.
Does this mean you have to become a vegetarian? Not necessarily, though, people who follow a vegetarian diet generally eat fewer calories and less fat, weigh less and have lower cholesterol levels than do nonvegetarians.
You can still eat meat, poultry and fish in moderation as part of a plant-based diet if you're willing to be flexible. Indeed, many people who eat this way call themselves flexitarians. Want to give it a try? It could be just the jump start you need to begin eating healthier.
Start by going meatless one or two days a week. On those days, try the following protein-rich foods instead of meat:
- Beans and legumes — great in casseroles and salads
- Vegetarian refried beans — good substitute for meat in burritos and tacos
- Tofu — perfect addition to stir-fry dishes
Plan menus that feature entrees you like and that are typically meatless, such as veggie lasagna, minestrone soup and pasta salad. If you need a snack, try a handful of nuts and some fresh fruit.
Do you have other suggestions for ways to transition to a more plant-based diet? Have you made the transition to a flexitarian or vegetarian diet? Please share your experiences.

Haven't had a fast-food burger in a couple of years, and after watching documentaries like Food, Inc. and King Corn, I've tried to stay away from High Fructose Corn Syrup and most processed foods. I recently started juicing fruits/veggies and I crave whole, raw, live foods now. I do feel much better and, because I am a 9 year out gastric bypass patient I also take an organic-based, living multivitamin. I just claimed the title "Flexitarian" Yay!

I use to call myself a vegetarian, but ate seafood. When invited to a dinner at someone's home I accepted meat as a sign of socialability - though having very mixed feelings about it. At home it's all veggies. Heard the term flexitarian a year or so ago. Now I had something I could live with.

I have decided to give this a try. I'm tired of feeling lethargic after eating. I don't like the feeling of a heavy stomach. I wish there was a website dedicated to this so I can learn how to transition successfully. I'm concerned that the lack of information and support could derail me. I'll keep Googling...

After being a life long meat eater I have decided to become a Flexitarian. I just finished a 30 day challenge where I was a total vegitairian. I have to say I never felt better. After having my gall bladder removed I just had so many issues with my digestive system inclusing reflux and actual pain. While on a vegetarian diet all that went totally away. I'm going to eat meat 2 times a week and make one of those time fish rich in Omega III. I'm looking forward to seeing what results this has on me physically long term.

I had no idea that this is what this was called. I recently due to a gluten allergy have had to drastically change my diet. I found it to be nice to eat one vegetarian meal a day excluding breakfast. If I eat too much meet my body feels like it craves for vegetables. What helped me switch over was eating a salad at lunch and dinner. Then I started trying other neat dishes with only vegetables like asparagus soup(easy to make, sweat potato fries and stir fry with tofu. After a while it just become second nature for me. Now if I eat something with too much meat my body hates me literally.Plus I found brown rice, tofu and beans to be very filling you almost forget about meat completely. the nice thing I have to admit that I have noticed about eating less meat is that I have more energy and lost some weight as well.

What a great idea! this has been a problem of mine. I want to be a vegetarian to improve my health but i like meat too much to drop it altogether. I will definitely try this. Going to go buy veggies by the bulk soon and then restrict the meat in my diet =)

I am on a protein shake diet now. I am not sure if this works but I have known some people who had this as their diet solution. I just think I am going to give it a go, to see if this can be working for me.

I gave up red meat and pork two-three years ago. Never was crazy about it. The last red meat burger I ate felt like it "stuck" for days! I mostly eat veggies....sometimes chicken, turkey, fish, seafood. I'll go days and only eat veggies...I don't plan it...it just happens...so I was happy to know there is a term for the way I eat!

I guess I have been a flexitarin all my life before it was popular. I was the only member of my family who preferred veggies to meat. I ate very little meat and prefer veggies. i eat them steamed without any gravies. sometimes a little olive oil or perhaps tomato sauce. I always preferred green veggies, the darker the best. I eat eggs, and for protein, I eat soy. but most of my meals contain many more veggies. I am 85 years old, still active, lift weights and many other activities. take care of myself and do not take any or need any medications. therefore, I highly recommend the flexitarian diet to all.

I went flexatarian (I don't eat meat but do eat fish) almost 5 years ago. I had my first blood work done last year since becoming a flexatarian. My cholesterol was lower and I had a perfect proportion of hdl to ldl. My iron was better than before and all other results were great. I feel good and find it easy to manage my weight. I wouldn't go back. I recommend the Whole Foods Cookbook, the Healthy Hedonist and all Moosewood cookbooks.

A few years ago I found I was almost in the same situation as Elsie though my thyroid was hyper rather than hypo. At that time they also found that I was anaemic as I did not wish to increase my problems with my thyroid I decided to have some white meat and fish but also had some red meat. I recently read that they are introducing new ways to 'grow' vegetables and fruits' and I am not so sure now that food from the land is really that.

What inspired me to give up meat was concern for the land and our planet. But all the reasons appeal to me from better health to issues of cruelty. Nevertheless, my biggest impediment to adopting a vegetarian diet was this conditioning we have that there has to be a "main" course on the plate, an entree if you will, and it must contain meat. Who made that rule?! A meal doesn't have to have a main course- it just has to have variety! Now I plan meals to be colorful with several different types of vegetables or beans and fruit along with a starch like corn, rice, pasta, couscous or potatoes. The whole thing is really a combination of "side"dishes. But it always looks pretty and good on the plate. I do sometimes eat soy foods and have not found it to be a problem even though I did come up hypothyroid last year. I don't think my being vegetarian, had anything to with that. It runs in my meat eating family. My diet has been flesh free for 17 years and I love my food! I'm never going back.

Cutting down meat consumption is taking a priority in trying to improve physical health. Thus, Meatless Monday, a project of Johns Hopkins Bloomberg School of Public Health, has a website rich with recipes from Breakfast (like these Buckwheat Apple Flapjacks: http://www.meatlessmonday.com/buckwheat-apple
-flapjacks/) to Dessert (Try this delicious Banana Nut Bread: http://www.meatlessmonday.com/banana-nut-brea d/). Meatless Monday’s efforts to encourage commitment to a weekly reduction in meat is gaining traction; for more info on the movement check out the Youtube video: http://www.youtube.com/watch?v=bpnKeYmR1NM - Ashwini

Registered Dietitian Dawn Jackson Blatner brought the most attention to flexitarian eating and has created one of the most healthful eating plans in her book The Flexitarian Diet. I highly highly recommend it!

About 5 years ago I guess I became a flexitarian. I had been a strict vegetarian for over 10 years but change because I noticed that my energy level had decreased. It turned out that I was hypothryoid. Since being diagnosed, I have stopped eating soy products and cruciferous vegetables. I am not sure if soy is truly bad for the thyroid but I would rather not take chances. I stopped eating cruciferous vegetables (kale, broccoli, etc.) because they are know to increase the size of your goiter. The good thing is that I am eating more vegetables and legumes along with seafood and some chicken. I think this makes for a healthy, balanced diet. Plus, I've lost weight which is always the best part of any diet!
