I would share rhe document given to me by my bariarric team. I'd keep it in a journal and begin my day by choosing my proteins and fruits and vegetables. You should have a nutritionist you can consult, and it's possible you could ask that person to help you a diet based on the fact that you need it in writing. Then divide the foods by category like protein, fruits and vegetables. carry this in an igloo and tote bags. Plan your daily eating based on these lists. You can find them here. Weigh and portions out in the morning and set them out in containers. Then they're premeasured and all you have to do is add the liquid of your choice. You can put premeasured portions in sealed containers and then add the liquid.
My food journal breaks it down and i base each meal on a component of the total nutritional items of the day. Even if you're traveling you can make Igloo congainers, well sealed, and simply dump them in your bowl or plate, then add the liquid.
I've posted the recipes for many, many meals here. They're on my profile.
traveling doesn't lead to failure as long as you begin with planning. plan in advance and then make your portions. Many of your choices can be all hte ingredients except the liquid and your choices of liquids can be paired with the portions. Stick with it. Traveling is often an excuse to fail. It doesn't have to be that way. Pack your foods along with your clothes and cosmetics.
But invest in the double freezer bags to hold each portion. Then all you have to worry about is mixing it. Dont go for the quick and easy kits and suggestions. Write it down and follow your plan.`
