You might be in a situation where your shopping list is more or less the same as before but minus the things you can't have. It is bound to leave a big hole. Gone for me are sweets, biscuits, chocolate bars, iced and jam doughnuts and other nice buns. All the things which gave me diabetes in the first place. There are plenty of pot holes which need filling.
Oddly enough, I am filling them with savoury foods which I have made myself, southern style chicken and prawn jambalaya, thai style prawn and noodle soup, ragu ala bolognese, indian mixed lentil curry, salt and pepper spare ribs and salt and pepper tiger prawns with egg foo yung and shrimps, lamb and barley stew. They are all very tasty and filling. If you have good tasty meals, you feel less inclined to go for the satisfying hit of a sugary snack. You tend not to need it as much. Most of these things are themselves filling a hole in the main diet, which is often lacking in taste and texture. If I need a sweet, I will mix a smoothie, usually made from some berries and plain yoghurt. Often during the day, a large glass of cold diet lemonade from the supermarket, zero cal, zero carb and probably zero lemons, but to which I add the juice of a freshly squeezed lemon. That is a very satisfying hit on the taste buds and will see you right for a couple of hours. The lemon actually does you good too but either way, you won't feel like you need that chocolate for a while. If I need a crunch, Lidl do a rye crispbreda with sesame seeds. It is very light and crunchy, and thinner than a ryvita and with a fish paste spread is much better than any packet of crisps. When supermarkets have it on offer, but a shoulder of pork to slow roast, 5 hours. Not only is the meat fantastic and keepyou going for a few days, the crackling with make for very many snacks. It's brill.
