Hopeless, a few thoughts which you might find helpful.

I think that you are eating in a very healthy way. You could consider adding some whole-grain products (for example, brown rice and whole-grain breads) to what you eat. These are low GI which means that their glucose is released slowly during digestion and are good sources of fibre and some vitamins and minerals. I appreciate that you have medical reasons for avoiding carbohydrates so this is just an idea.

As a rule of thumb sustainable weight loss involves losing no more than about 1 kg (about 2 lb) per week - more than that may not be sustainable.

You could see what is called here an Accredited Practicing Dietitian (APD). APDs are qualified health professionals who can review the food intake of their clients and make constructive suggestions.
