How to get started

Hey Pam! My big tip for you, because you seem to be in the same boat as me - fell off after high school and into college after being super athletic, is to keep your favorite fruits readily available. Simply subbing chips out for a piece of fruit once a day will make a difference and after doing this you'll want to make even more healthy choices.

For me, I don't cut anything out, I just limit my portions. Make healthier choices easy. If you know you are the type that can't just have a small serving of chips, try cutting it out for the first two weeks then slowly introduce it back in.

Wait...

Height: 5' 6''
Weight: 126
Daily calorie goal (not including exercise): 1200

Your profile says you want to be 112?!
At your height, you should be 115 - 150, so you're already right in the middle of a healthy weight range.

Instead of trying to starve yourself to get below a healthy weight, try adding (or stepping up) weightlifting.
You'll reshape your body, lose inches, and look lots better.

Here's a calculator which will show you your BMI, plus how many servings of which food groups you need to maintain a healthy weight (which you're already at).

Here are several calculators to tell you your BMR & total daily calories

They'll give you slightly different results, but you'll have an idea of what to aim for.
At 126, your BMR is about 1260. Being fairly sedentary you should have about 1770 cal per day to maintain weight.
That will probably be enough to let you do weightlifting & the recommended 30 min per day of cardio.

Here's an article from the American College of Sports Medicine which shows a 7-minute body weight workout.
No gym needed. Repeat it several times in a row for the most benefit.
