babyjane,
You are eating way too little! I know that can be a difficult concept to grasp when you want to lose weight (believe me, I know)! For your height, weight and age, your BMR (the total # of calories your body burns for normal bodily functions) is 1647 calories. Factor in your daily exercise, depending on the intensity and that # goes up.
Let's assume you you are moderatley active, then the # of calories you need to maintain your current weight is 2553 calories per day. To lose fat, you need a calorie deficit but too much of a deficit for too long and your body will not burn fat!
Right now, your body is in starvation mode from lack of calories. I recommend you consume 2000 calories a day to lose a pound a week. At absolute minimum...765 calories but every few days eat 2553 (your maintanance calorie count) so that your body isn't convinced to hold onto extra body fat to withstand the famine. Eat 5 meals a day or every 3 hours and divide your calories pretty equally through out the day, if anything, less in the evening since metabolism seems to slow down at night.
Also, no deficit larger than 1000 calories per day...that is too much for anyone. 1000 deficit will equal 2 pounds a week since there are 3500 calories to a pound.
FYI, I used the The Harris-Benedict formula (BMR based on total body weight) to calculate the # of calories you need to maintain your weight and how much to lose a pound a week.
I cannot tell you enough how much you will be helping your efforts to lose weight by increasing your calories a bit.
Also, make the foods clean...get rid of the junk. None of the above will work if you are eating donuts, chips, ice cream and all the other crap! I have noticed the less sugar I have, the less I crave it. Even a little makes me hungry, moody, tired and wanting more.
For the record, this is my opinion based on the many years of nutritional research I have done during my free time. I'm not an expert, just an enthusiast. It is certainly working for me! Wish I knew it before I walked down the aisle!
