1. Pace yourself.
Start by eliminating red meat. After a couple of weeks, no more poultry (including eggs). Then, get rid of dairy and - finally - seafood.
2. Don't replace meat and dairy with carbs and unhealthy foods.
This is a common mistake. If you're a vegan, you have to actually eat primarily fruits and vegetables. While they're allowed, avoid filling up on potatoes, rice, nuts, and salty snacks.
3. Keep it to yourself.
Sure, you're excited about this journey towards veganism and want to share it with the world. Unfortunately, not everyone is going to get it. Don't be surprised if even some friends and family members tease you or discourage the idea. It's better to play mums the word for awhile until you're confident enough with your new lifestyle.
4. Find support.
Social media is awesome for this. Join a Facebook group. Follow Instagram and Twitter accounts that keep you motivated.
5. Prepare accordingly.
Being a vegan has nothing to do with starving yourself. Because you're eating primarily fruits and vegetables, you're going to find yourself eating a lot more often. Be sure you stay on track by always having a healthy snack handy - like baby carrots or apple slices - to get you from one meal to the next.
