Hi,
You just had surgery and you worry about not enough weight loss? Give your body time to heal and adjust. Relax and work on following your food program and stay off that scale if you can. Find some wonderful things to do, hobby or activity that will keep you focused on other things. Before you know it, your clothes will feel roomier and THAT is a great indication of weight loss. Can you do that?
Also, it would be nice if surgery healed the brain as well. It is important that all of you learn to develop a healthy relationship with food and make some permanent life style changes. If possible, find a support group, nutritionist, and/or counselor who specializes in food issues. This is a whole body journey and your success will be greater if you can get all the support possible.
The full sensation is something that I can't help you with. One thing I do is use smaller plates, bowls and focus on portion control. As I said, it is important to develop healthy habits and help your body get the results you want.
I hope this helps. Yea I don't mince words. I say what is realistic and it is a journey that can be positive if we take the right steps to help ourselves by getting the support we need.
I am so happy for you and your family. You are on the road to a healthier you!
