I have been a vegetarian (well, technically I eat fish 1-2x a month) for 11 years. While I definitely think eliminating factory farm animals from one's diet is good for health, I don't think animal meats in general are "bad" for you. Meat isn't "loaded" with saturated fat, and saturated fat is an important part of one's diet.
I gave up meat cold turkey (hehe) so I don't know if I have tips on helping you stick with it. But... I don't think there is anything wrong in simply reducing
the amount of meat you eat if you enjoy eating meat. I think in the vegetarian/vegan world there is too much emphasis on labels- being "vegetarian" or being "vegan." You can be healthy eating meat and you can be unhealthy being vegetarian. The important thing is eating LOTS of fruits and vegetables, keeping carbs in moderation, and eating none or a modest amount of animal products. (As Michael Pollan says, treat meat like a garnish or side dish.)
There are of course ethical or personal reasons why some people live strict vegetarian/vegan lifestyles, and I understand why those individuals want to stick to that 100%. But if your motivation is health and you think it would be easier to "stick with it" if you eat meat on occasion, that's great.
Your plan to eat veg 5 days a week is a great one. The most important thing is to up the fruits and vegetables. I guess my bottom line is don't sweat the label of "vegetarian" if it is something that's difficult to stick with
