take a look...

More water.

Definitely more water.

You need to make friends with some vegetables :-) I didn't see any and I went back about a week. They're full of all kinds of good nutrients and fiber. If you don't like them normally, try some different recipes and ways of cooking them (my dad hated his veggies, but he loved stir fries...). A salad and about a cup of cooked veggies a day would be a good start (or maybe some raw veggies with hummus or a low cal dip?). Also, drink more water and add some variety in your diet - try some different fruits, maybe.

I was told, and I've been doing this ever since, is you should drink half your weight in ounces of water daily. The words don't make much sense.

I started losing at 300 pounds. So I was drinking 150 ounces of water daily. Yeah, almost 20 glasses of water. I bought a 40-ounce canteen, and we have a super cold water filter here at work. Fill it up four times, and I've hit the goal.

I'm now at 275, so I'm drinking 140. Three and a half on the canteen.

If you weighed 150, you should drink 75 ounces of water, which would be about 9 glasses.

Make sense?

anyone have any suggestions for veggies?

Peas are my favorite. Next up, beans -- because they have great protein too. Lastly, broccoli.

I like the idea of drinking half your weight in oz...but if you are under 128 lbs then you should drink at least 8 glasses a day/64 oz... I am not too good with drinking water but adding lemon and ice and using a straw often helps believe it or not, and I shoot for 10 glasses a day even if I have to force it down sometimes.

OK, you're only sixteen, so my first rsuggestions would be that you should look at recommendations specific to someone your age - your body and brain still have some developing to go so it is really important that you are getting good nutrition at this point in your life. Is it an option to see a nutritionist to get an eating plan that's designed for you and your goals?
If not, have a look online for healthy eating for teenages and see what you can find.

In general I don't think you are eating enough real food. Fruit for lunch and a PB sandwich for dinner aren't bad in themselves, but they won't be supplying all you need. You don't have to eat meat if you don't like it, but you do need to balance your diet. If you are going to be vegetarian you have to work at it, and make sure you get all the right nutrients. Having to have injections every week for months because you didn't look after your diet is a bad idea (trust me, I've been there!!)

It also looks to me as though you aren't eating enough calories. Going too low in calories at this point seems like a really bad idea, you don't want to end up as an adult with all the eating problems that so many of us have. Get some advice specific to your stage in life and make the most of this opportunity to grow into a healthy adult!

I make a lot of dishes with light sauces, and I have a trick to eat more veggies. If I am eating a pasta dish I put the pasta on the plate, top with a heaping serving of veggies (frozen peas, carrots, green beans, anything you want to try) and top with extra sauce.
The veggies help me eat less pasta and the sauces that I make are healthier than butter.

Another favorite trick is to add carefully measured amounts of parmesan cheese and bread crumbs to sauteed spinach or green beans. Shredded parmesan cheese is a favorite of mine because it gives a lot of flavor, but you only have to get a tiny bit in every bite to get that flavor. Just make sure you are measuring how much you are adding, because it is tempting to go overboard.
