Before switching to a vegetarian diet, nutritionist Suzanne Havala says that it's important to be educated about diet. Many people have figured out what they don't want to eat but haven't figured out what to eat. The biggest downfall, says Havala, is eating a diet of iceberg lettuce salads.
People get hungry and crabby.
Another downfall is too much dairy which is high in fat. Making The Switch Havala suggests taking a look at what you already eat that is vegetarian and focusing on those foods. She says that many people are surprised at how many vegetarian items they eat on a regular basis. Another trick is to focus on color. Vegetarian foods are usually the colorful foods so if you have a colorful plate, you are likely eating a lot of non-meat items.
