Hi and welcome.
Please don't wait until you reach that goal before you come back to us.... we are here to support you the whole journey, not just to share your success.
Cutting your carbs really can make a big difference.
There is conflicting dietary advice for diabetics, and the NHS may be somewhat behind the curve because they still recommend moderate wholemeal carbs and low fat. This will often not reduce your BG levels and leave you feeling hungry which will make sticking to it difficult long term and we need to make this a lifestyle change not a short term diet, so enjoying what you eat is important to success.
Eating some dietary fat like creamy Greek natural yoghurt rather than low fat (which is higher in carbs) will help to keep you feeling fuller for longer because fat is slower to digest than carbs, provides slow release energy and it tastes good. I have it for breakfast with a few berries and a tablespoon of mixed seeds and another of chopped nuts.... again the nuts contain fat to help keep you full. Berries like rasps, strawberries, blackberries, black and red currants (not the dried fruit currants) or some stewed rhubarb (with a little sweetener) are the lowest carb fruits This yoghurt, fruit, seeds and nut mix makes a great breakfast. Eggs are another great choice for breakfast. I like to have a 2 egg omelette with a variety of fillings including any combination of mushrooms, onion, peppers, courgettes, aubergine, ham and cheese. I have it with a large leafy salad and some creamy coleslaw (not reduced fat coleslaw). That usually lasts me until tea time without the need for any lunch or I have a chunk of cheese or a handful of nuts or some olives if I feel peckish.
You are really looking to reduce your consumption of bread, pasta, rice, couscous and potatoes and anything made with grains/flour and also fruit, which is of course normally considered healthy, but often contains lots of natural sugars.
Cauliflower is a great low carb alternative to use. It can be cooked and mashed with a dollop of cream cheese and a spoon of mustard or grated and used as a rice or couscous replacement. And who doesn't love cauliflower cheese..... but instead of making a sauce using flour and milk you par boil and then coat in cream cheese and then grated cheese and brown off in the oven. I mix a spoon of wholegrain mustard into the cream cheese and some sour cream and chive dip which gives the cream cheese a softer consistency for coating and more depth of flavour and then a mixture of Red Leicester, Mature Cheddar and Parmesan to top it. Some people experiment with other herbs and spices. It tastes great with gammon or high meat content sausages or pork chops/steaks. You can use the cauli mash to top a cottage or shepherds or fish pie instead of potato. Cauli can even be used to make a pastry alternative together with parmesan cheese to make a quiche base instead of flour, resulting in a very low carb quiche.
It is also helps to increase your activity levels and it doesn't have to be anything overly energetic. A brisk walk is one of the best ways of reducing your BG levels and with this wonderful weather, it's a real pleasure to get out and "swing your legs" in the fresh air. Even with very limited mobility, doing some seated exercises with your arms and legs each day will be beneficial.
Hope this gives you some idea of how to move forward with this. There are plenty of other food and recipe ideas here on the forum. Learning what to buy and how to cook it is key and reading nutritional information on the back of food packaging is key to not buying the wrong things.... you need to look at the total carbohydrate content not the sugars and take your specs as it is usually in tiny print on the back or side.... not the traffic light info on the front which is always easy to see but not helpful to us diabetics.
If you don't understand anything just ask and we will do our best to explain.
Good luck!
