\"My weight stayed the same and I lost one point off that dangerous internal visceral fat, so even someone doing this just one or two days a week could potentially have some health benefits,\" she said. \"My advice is dip your toe in the water.\"
\"It doesn't have to be all or none,\" she said. \"You could start with just one day of plant-based eating then maybe that will lead to two but, listen, if I can do it, anyone can do it.\"
What is a plant-based diet?
A plant-based diet is a way of eating that consists mostly or entirely of foods derived from plants, including vegetables, grains, nuts, seeds, legumes and fruits.
Thomas Colin Campbell, a Cornell University biochemist, claims responsibility for giving the plant-based way of eating its name. He said he coined the term in 1980 to \"help present his research on diet to skeptical colleagues at the National Institutes of Health,\" according to The New York Times.
\"I wanted to emphasize that my work and ideas were coming totally from science and not any sort of ethical or philosophical consideration,\" he told the newspaper.
Is a plant-based diet different from a vegan diet?
Yes, a plant-based diet consists of eating few to no animal foods, while a vegan diet eliminates all animal foods and products -- everything from meat and leather products to eggs and cheese, according to Fatima Cody Stanford, M.D., an obesity medicine physician scientist at Harvard Medical School.
Plant-based diets are also different from vegetarian diets, which eliminate all meat, fish and poultry, according to Stanford.
While religious, cultural, or ethical reasons often motivate veganism and vegetarianism, plant-based diets are often done for health and environmental reasons.
Plant-based diets also often place an emphasis on whole foods.
\"There is a way to be healthy in any of those,\" Stanford told \"GMA\" last year. \"What I say to my patients is to find the best right thing for them because everyone’s body is different and everyone’s body responds differently.\"
Why is there so much interest in plant-based diets?
Plant-based diets have been steadily gaining acclaim for the last several years, often landing atop the annual best diet rankings from U.S. News & World Report.
The 2011 documentary \"Forks Over Knives\" also really put plant-based diets into the mainstream. The documentary was made by Brian Wendel, who attended a conference on nutrition in 2001, began to follow a plant-based diet and then brought the idea to the masses with the documentary and a best-selling book.
\"The information has been there for a long time, at least from a health perspective, and we’ve just helped bring it to a mass audience,\" Wendel told \"GMA\" last year. \"I became convinced of the health argument back in 2001 and just did it overnight. Up until that point, I had been eating animal products every day.\"
More recently, another documentary, \"The Game Changers,\" has pushed plant-based diets into the spotlight. The 2019 documentary, produced by James Cameron and Arnold Schwarzenegger, shows the journey of a former MMA fighter who gives up meat.
Celebrities like Kim Kardashian West have also been public about embracing a plant-based diet, increasing interest in the way of eating.
Another factor is the argument that eating plant-based is better for the environment, according to Deirdre K. Tobias, assistant professor in the department of nutrition at Harvard School of Public Health.
\"We see how much land it takes to supply and grow a single hamburger, for example,\" she said. \"I think that awareness has been really eye-opening for a lot of people who may have disregarded the dietary advice for health reasons.\"
What are good things to eat on a plant-based diet?
Wendel, of \"Forks Over Knives,\" places an emphasis on eating whole, minimally processed foods within a plant-based diet.
\"For me the best guide is does the food still look somewhat like it does when you take it out of the ground? When you cook a potato, it still looks like a potato,\" he said. \"The more a food is like that the more you can lean on that in your diet and lifestyle, for health benefits.\"
Of course fresh vegetables and fruits are a big part of a plant-based diet, as well as nuts, whole grains and legumes. Seafood and meat products can also, on occasion, be part of a plant-based diet.
Wendel emphasizes eating more than just vegetables on a plant-based diet to ensure you are taking in enough calories.
\"Make starchy foods -- beans, rice, sweet potatoes, quinoa, chickpeas –- the center of the plate because that has the energy to sustain you,\" he said. \"And then surround it with vegetables.\"
