My entirely non-professional opinion is that it is more important that you eat than what you eat. Lay in a supply of low-carb food that you can eat with no or minimal preparation. Some possibilities are: tinned meat and fish cheese nuts peanut butter hummus whole grain bread, crackers, and cereal ready to eat fresh vegetable and those you are willing to eat cold from the can deli salads low fat, low sodium canned soups high cocoa chocolate bars If you have a microwave: microwave dinners, frozen vegetables, frozen fish. In this country I can get prepared meats that can be cooked/heated in the microwave and will last several meals. If you have some energy to cook, boiling eggs does not take much and they will last for a week in your refrigerator. Once you are eating regularly and maintaining your blood sugar level, you may have more energy for cooking (or whatever is most important to you to do).
