HEY EDWINA ~ there's an even easier way to eat healthy to lose weight than counting calories; USE PORTIONS; by using a dinner plate or bowl to serve your food in.
DINNER ~ 1/2 plate VEGGIES; your choice
1/4 plate LEAN MEAT like chicken, steak, fish, turkey
1/4 plate WHOLE CARB like potoatoes, brown rice, beans, pasta
LUNCH ~ one sandwich of your choice + one fruit + 1 or 2 % milk (have soup on weekends, or a cup-a-soup; so ez)
BREAKFAST ~ small bowl of whole grain cereal with milk + one fruit OR vary with toast and cheese or peanut butter on weekends
DESSERTS & SNACKS ~ any fruit, handful of nuts, 1 oz cheddar cheese; once a week have some low-fat popcorn (say on weekend night); once a week allow yourself one light dessert with your family.
For exercise, start off walking the halls at school; walk to school if possible; walk after school in a park; work your way up to speed walking and carry some music to make it fun. In the evening, try some toning stuff like stomach crunchies (as mentioned), hand weights, jumping jacks, or steps to bouncy music. Can you join any intermurel sports in the lunch hours that you like? For instance, basketball or soccer really burns the energy fast! So does hiking!
I am also short and was your weight in my late teens; if you eat healthy like this ALWAYS, you will lose the weight; and will not gain it back (I wish that someone had told me that back then). The key thing is to get the junk foods out of your menu; they are so high in calories that they pack the pounds on. When I choose foods now, I ask myself this question ~ IS THIS HEALTHY FOR ME, OR NOT?
That is not to say that you can never have your favorite foods again; the issue is how often and how much! One slice of pizza with a salad is OK for a treat once a month when you are trying to maintain your loss. Right now, you are trying to lose some weight; so cut that stuff out for now and have a pizza omelette instead. Use your imagination and you'll come up with some great substitutions ...
I don't know exactly how old you are, but if you are in junior high, likely early teens; you must eat balanced to make sure you stay healthy (as in still growing). Take a daily vitamin to make sure you are getting all your nutritional needs met; and talk to a doctor to make sure you have no health issues before starting to lose weight. I hope some of these ideas are helpful to you ...
