Have you tried low carb or keto, that’s what most T2 on the forum use to control their blood sugars which some of us have found it’s a relatively good way to lose weight also.
So reduce or cut out carbs such as potatoes, rice, pasta, bread, flour products, grains, legumes. All sugary stuff, breakfast cereals
Lovely things you can eat, all meats fatty cuts are better, fish, above ground veggies, butter, cream, cheeses, berries. Full fat Greek yogurt. Good oils like olive oil and nut oils, avocado, bacon, eggs
The idea is that fat is more satiating than carbs, carbs make you hungry fat will keep you fuller for longer but you will also eat less, probably no need to count calories unless you are eating massive amounts. Just eat until you are full. You may find you will begin to skip meals if you eat to your hunger. Have a read around the forum especially the low carb recipes and what I’ve eaten today threads for ideas on what you can eat
