I wouldn't do it, there are certainly other just as effective ways to change your diet in a positive way.
What I would recommend ~
Drink a gallon of water throughout each day. This alone will do wonders for your skin, your hair, your teeth, how much energy you have... Everything.
And then, start cutting out gluten from your diet. Swap out junk foods for berries and fruit, and go look into what super foods are such as kale or spinach.
- microwaves are a no no. Your scrambling the DNA of anything that's out in their and most of the nutrients you could otherwise get are destroyed. In fact I think you lose around 70% of somethings nutritional value after cooking it due to breaking down certain fatty chains and what not.
- try weaning yourself off fake sugars, anything that says sucrose or glucose is bad.
I also personally feel that it's just much better for your body to eat vegetables raw and uncooked (but washed).
With just that small amount of advice theres no reason you'd need to go vegetarian.
