If you decide to lead this lifestyle, it is important that you replace all the nutrients that animal products offer by plant sources. This is necessary because there are nutrients like iron in meat and some others that are necessary for your body. In this way your health will not be effected.
A very practical tip to start a vegan diet is to replace meat as an ingredient in recipes, such as legumes, cereals, tofu, seitan or various products already made from soy such as veggie burgers, meatballs, sausages, etc.
There are a lot of people who make challenges for a certain time, such as the famous "30 days Challenge" or “veganuary”, and finally we choose this lifestyle because there is an immense variety of delicious vegan food. It is very easy to veganize any almost of your favorite dishes. For example if you are a burrito lover you can easily convert it to a vegan burrito. According to my experience, following a vegan diet is not complicated because there are healthy and delicious substitutes to traditional food.
