One of the hardest parts of a healthy lifestyle is figuring out to start. That's what I love about vegetablarianism. It can be a baby step or a giant leap, whether you start fron "junk food junkie" or "eating healthy most of the time." That's because vegetablarianism does not require you to give up anything; the eventual strategy is to crowd unhealthy stuff out with healthy vegetables and fruits. "Baby steppers" can start by simply adding a small amount of vegetables to their existing diet as-is. "Giant leapers" can strive for an extremely significant increase in the proportion of vegetables in their diet. Becoming a strict vegetablarian, where you eat vegetables and other healthy foods to the exclusion of unhealthy foods, would be considered a giant leap for most. What is important about this is that research has proven that the most effective way to to achieve permanent behavioral change (for example in your behaviors around eating, especially eating healthy) is to create new habits slowly and incrementally. For this, vegetablarianism fits perfectly. It's easy to add a vegetable here and there, becoming gradually more and more conscious of eating more and more vegetables. It is also psychologically easier (read: creates less stress) to create positive change (eating more vegetables) than negative change (not eating something in your current diet).
So, if you are looking for a jumpstart to making a lifestyle change, join the vegetablarian movement! And take your baby step to a healthier lifestyle!
