Father, the emotional issues that effect eating will not be gone. Help her to be in your will and go where you lead her to deal with this problem.
There is still a lot of struggle after this surgery with eating habits. I just saw a program about it which interviewed people who had the surgery and the problem they face after it.
This program did not cover any of the medical problems that people have, but the control of eating that still has to be faced.
I, personally, believe that God can do a work in us showing us how to overcome these problems in our lives and teaching us methods for success. And helping us to develop maturity and contol in our lives.
I have had a lot of eating problems and find that even a half day fast, as led by the Lord, will help break that food lust that drives your eating. I have to do that often, because I get bound again quickly. Sometimes for a period of time I have fasted mornings. It also cuts down on the hours a day that you are eating. We gain weight when we eat late at night. So if you can stop late night eating and limit yourself to certain hours, it will start shrinking your stomach. You can then allow yourself to eat nice meals to full, not overfull during those hours.
Also, concentrating on eating healthy foods and exercising helps a lot. Who wants to move to exercise if you are stuffed.
The Lord started ministering to me that food was taking over and I wasn't having anything else in my life. It was costing me everything.
I started trying to let him get my focus off food all the time. What delicious thing was I going to stuff myself with next. And then be too miserable to do anything until I wanted to eat again and had to prepare more food.
I was married but most of the time too stuffed to enjoy sex. etc. Didn't want to do outdoors things, couldn't move freely. You become chained to the refriderator and stove.
That is not a full life. Even eating become boring after awhile and you are not really satisfied.
Like anything else, when you try to walk in God's way instead of your own, you start making progress in another direction. He will help you, even though you feel you fall many times. You will progress farther and father, both physcally and spiritually.
Any area you conquer helps you to be more confident to be able to master other things.
We are called to be overcomers. Hard isn't it. lol
Love,
Robin
