A flexitarian is someone who primarily follows a vegetarian diet but occasionally includes meat or fish. This approach allows for greater dietary flexibility while still emphasizing plant-based foods. Flexitarians often focus on consuming fruits, vegetables, whole grains, and legumes, making it a healthier option for many. The flexitarian diet is popular for its potential health benefits, including weight management and reduced risk of chronic diseases. It also promotes sustainability by encouraging lower meat consumption, which can lessen the environmental impact associated with meat production. This makes it an appealing choice for those looking to improve their diet without completely giving up animal products.
