first week

Also, eat your full 1200 calorie allotment every day and at least half your exercise calories (preferably all if you can accurately calculate caloric expenditure). Looking at your diary on several days you have eaten too few calories. Although the concept of accelerating weight loss by reducing caloric intake is appealing, it will likely backfire on you. A lot of people get in trouble eating too few calories and quickly stall out...that hasn't happened to you yet, but you really want to avoid that problem...

You will find this process will have it's ups and downs. Don't get discouraged...patience is your friend. Take some measurements now, before you start, so when the scale won't move you will see the change in the tape measure. Also, take some pictures now and then monthly going forward. Provides great self motivation and also gives you something to post in 6 or 8 months to provide encouragement to others.

That isn't 4 lbs of fat...that would take an enormous amount of calories, but you should log everything. I noticed I nibbled a lot during the day and sometimes stopped when I realized I didn't want to log a second cookie or piece of bread.

I gained 2 lbs after losing 3 my first weeks, but a few days later, it dropped again. I agree about the measurement and just how your clothes feel. Sometimes your muscles swell though in the beginning and muscle does weigh more, go on how you look and stick with it.

I was a firm 135, running marathon years ago and also was 140 another time in my life and was soft and overweight (a size or more larger) after a baby...you can be the same weight and look very different, depending on what is making the pounds. Try not to lock too much into that.

Good luck with the twins, I had 3 kids and twin girls too....that is a workout in itself. ; )
