I don’t know where you live but i don’t think all meal replacements need a prescription. But at the same time if you don’t try some new foods what’s going to happen when you go back to your old patterns when you’ve attained your goals by meal replacements?
Not loving fruits is not a big deal on the blood sugar diet … berries are preferred anyway … strawberries, raspberries, blueberries, blackberries ….
You can have : fish, chicken, all kinds of unprocessed meats, even smaller quantities of processed meats, even a couple of rashers of bacon with eggs in any form you like. Nuts and seeds, beans and lentils, cauliflower, broccoli, greens, peppers, spinach, snow peas, sugar snap peas, full fat yogurt, grape tomatoes, you could make chilli, soups, piece of your favorite cheese.
Have you tried all the vegetables? Raw? Steamed with some butter … maybe garlic butter? Maybe you would like some of these things if they were prepared in a tasty way???
Make a pot of soup : i just use store bought stock … add any vegetables, lentils, beans, meat. I put them in 1 serving containers in the fridge … no fuss, no muss, meals for days.
I make up some hamburger patties with some chopped onion … fry them up … eat some and put some in the fridge. Don’t really need a bun … it’s like a hamburger steak … put some fried onions or cheese on top.
It is really not so difficult … you don’t even need recipes unless you want to try some … there are lots of good ones.
The 8 week plan is really a training program for most everyone in eating healthy foods.
Just some thoughts you may want to consider.
