Welcome to the forum. I put weight on after an early menopause at 41 and did little about it. I was diagnosed with high blood pressure a decade later and sadly wasn't encouraged to and didn't, lose weight or exercise more. If you were in the diabetic range 48 and more, you would be told to look at diet, movement and try and drink more water. It seems to me even if you hadn't been told you were at risk of diabetes you know you need to lose weight.
I'm no dietician but I'm sure it would be better to try and have a smaller meal in the evening and have breakfast or lunch.
I enjoy full fat Greek yoghurt. I buy from M and S but haven't also bought Greek or Greek style from other outlets. I add berries raspberry strawberry or blueberry and some nuts. Sometimes I add seeds too. Or I have a mushroom omlette. I suggest you Google what to eat and what to avoid for arthritis or if you know already that's fine and don't eat anything bad for you.
I go to an aqua fit class. Is it something you could try. You need to be comfortable in the water but some of my classmates wear their glasses. You do not go under water. I was told my cholestral had crept up so i limit processed meat but a cooked breakfast of egg bacon possible sausage plus tomato and mushroom is low carb. A piece of toast too if you like.
Could you drink green tea or water with lemon juice some of the time? Perhaps in the evening have decaff drinks. Generally fruit juices are very sweet
Write down over the next week what you are eating. Work out carbs [ and calories] Carbs turn to sugar. You want to reduce portions of carbs like bread and potato or stop eating items, I've stopped eating rice and pasta or eat substitutes like cauliflower rice or edamame pasta. I have a slice of cake or an éclair or pastel de nata very sparingly. I started losing weight as I reduced carbs. I didn't count calories but you could look at calories.
Some veg like carrots are starchy generally veg below ground. Eat more veg. Perhaps 2 x above ground veg plus one below. I eat quite a lot of fish.
I found when I was awaiting my test results I cut cakes pastry processed meat and reduced bread and potatoes and was delighted I lost weight and wasn't hungry.
You do not need to be strict. With a few changes and choosing things with fewer carbs your blood glucose will lower
You could choose a tighter rein and reduce your weight and lower your BG.
Don't add sugar to drinks. Do without ( gradually) or use sweetner.
Movement could be generally stretching
Here is a good nhs website with links to lower carb eating. Some go below 50. Given your weight I'd try 100 to 130. Good fat and protein keeps you full. One of the websites they link to is Freshwell which has meal plans and a good graphic
