Here are the three key principles of Flexible Vegan Diet:1. Eat more plant-based foods The core of Flexible Vegan Diet is to focus on consuming a variety of plant-based foods, such as vegetables, fruits, whole grains, legumes, nuts, and seeds. These foods are rich in dietary fiber, vitamins, minerals, and antioxidants, which are essential for maintaining good health.2. Reduce meat consumption Flexible Vegan Diet encourages reducing the intake of meat, but it does not completely eliminate it. It is generally recommended to limit meat consumption to 1-2 times per week, with each serving being about the size of your palm. Fish, eggs, and dairy products can be consumed as alternative sources of protein.3. Tailor to your individual preferences and needs Flexible Vegan Diet is a flexible approach that can be adapted to individual preferences and needs. For example, you can choose to have one meat-free day per week, or you can aim to include at least half plant-based foods in every meal. Additionally, if you have specific dietary requirements, such as weight loss or chronic disease management, you can adjust your flexible vegan diet accordingly.
