Introduce yourself to the audience. It would be helpful to share how long you have been a vegan and your reasons for becoming a vegan. If you have any other relevant credentials, such as being a registered dietician or a general physician, mention this as well.
Begin the informational section of your seminar by introducing your first set of topics. Some examples might be: What is a vegan? What are the most common reasons to embrace veganism? How many vegans are there in the United States? What does a vegan look like? What do vegans eat? Is veganism healthy?
Start the multimedia presentation, if you have one. This could be a short video or a series of illuminating slides.
Transition into your second set of topics. Some examples might be: How do vegans ensure that they get enough protein, vitamins and minerals? Is veganism safe for children, pregnant women and seniors? What do vegans eat for breakfast? If you want to do a cooking demonstration as part of your vegan seminar, take the opportunity to do this now.
Pass out a handout with a list of your key points, information about veganism and some vegan resources for the audience to reference after your seminar. You can also add your contact information.
Ask the audience if they have any questions about the information you shared. Call on different people and answer their questions to the best of your ability. However, if you don't know the answer, then say so. Do not make something up. However, you can volunteer to find the answer and contact the person who posed the question after the seminar.
