Notes

FOODS
Foods to stay away from would be simple carbs like white rice, white pasta, white bread.
Also I would stay away from things high in sugar like any juices(apple and orange), high fat milk (2 and 3%), lollipops, sugary cereals,etc.
Stay away from things like ritz, most chips, cookies, ice cream, and lots of fast food places are unhealthy.
HOW MUCH YOU NEED TO LOSE?
This is exactly what you need to get started on your weight loss and im almost certain you can lose this weight by the summer.
According to this website http://www.healthcentral.com/diet-exercise/ideal-body-weight-3146-143.html?2,5,5,180,2 you are roughly 30pounds overweight which is not that bad and wont be too hard to lose. You need to lose roughly 30 pounds to be at a healthy weight so your goal should be 150.
HOW MANY CALORIES?
Alright Shanjai so according to this website http://www.iifym.com/iifym-calculator-3/ which calculates the amount of calories you need depending on your height, weight and age; you need roughly 2050 calories to maintain the weight you have now.
But for since you want to lose weight the website suggests you eat roughly 1640 which means that you are eating a calorie deficit of about 400.
WHAT IS A CALORIE DEFICIT?
A calorie deficit is a state in which you burn more calories than you consume. For example, if you burn 2,500 calories per day but only eat 2,000, you have created a deficit of 500 calories per day. A calorie deficit forces the body to use non-food sources of energy (typically body fat though the body can also burn muscle tissue for energy) to make up for the shortfall causing weight loss. A pound of fat is roughly 3500 calories.
BASICS
So now that you know you must lose 30 pounds it will roughly take you anywhere from 25-30 weeks if you eat proper everyday.
You also need to eat about 1650 calories a day.

EXAMPLE OF DAY
For Breakfast you should be eating foods like oatmeal, cereal, toast, eggs, egg whites, yogurt, fruit etc.
Some good Combinations would be a piece of toast and a boiled egg; egg whites and toast; oatmeal with fruit inside; etc.

For Lunch I would suggest you eat a salad with chicken and some carbs. You can get carbs from fruit, nuts, bread, yogurts.

For Dinner I would eat meats like chicken,pork,steak, and avoid things like hamburger meat and mainly stick to chicken.
Sides for Dinners should include one carb and vegetables.
Some good sides include beans, brown rice, boiled or baked potato, boiled or baked sweet potato, quinoa, etc.
Some good veges include broccoli, avocado, corn, beans, lettuce, cabbage, cauliflower, cucumber, bell pepper,etc.

Snacks should be a mixture of a little protein and carbs.
Some examples of good snacks are nuts(cashews,pistachios,walnuts, sunflower seeds,etc),fruits(apples,bananas,oranges,strawberries,watermelon), yogurt, saltine crackers, etc.
FINAL THOUGHTS
You should be counting your calories everyday on websites like caloriecount.com so you can accurately know how much you are eating everyday.
I would also suggest you getting a scale to weigh your foods so you know how much you're eating.
You need to eliminate all other beverages besides water and milk sometimes.
Healthy takeout in the mall includes most things at cultures, many subs, and teriyaki.
If you need help choosing then I can go with you.
MAKE SURE YOU ASK ME QUESTIONS ABOUT CERTAIN THINGS YOU DONT UNDERSTAND.
