EAT REAL FOOD. SIMPLE FOOD. COOK IT YOURSELF.
None of this McDonalds crap. If it's out of a box, chances are it's a "food product," not food.
Drop the pizza, junk food, etc. Limit sugary beverages (even "real" fruit juice should be limited).
My personal simple solution is to eat a green and a protein at every meal, with a starch here and there for good measure.
For example:
Eggs and Spinach, Grapes (some fruit) for breakfast
Fish (or Tofu), potatoes and asparagus for lunch
Gluten (Seitan) stir fry for dinner
Bunch of fruit and water between. Supplements if necessary.

Also, as a former vegetarian I have to state - even as a veggo I knew there was more suffering on a plate of kale and potatoes than a plate of steak and potatoes. This made me question a whole slew of personal ideas about alturistic eating.
While now ingesting fish (and feeling much better physically because of it), I still eat more than my fair share of veggies.
Keep in mind the death per pound of food logic. One cow or pig or lamb can feed people for weeks (or longer) and the body can have uses beyond food. An equivalent amount of rice/beans - tofu - or gluten would (in most cases) result in a multitude of pest elimination. Which one is more humane?
Just how many bugs die to get those greens nice and leafy and full? Just how many field mice and rodents died for your bowl of salad?
So while nothing eating but vegetables for moral reasons is an admirable thing, the amount of work needed to stick to such an ideal is simply prohibitive. Any vegetarian claiming to help the world, whom doesn't raise and eat their own food, is a hypocite at best. Catch phrases such as "organic" don't do anything but complicate the matter.
