Exercise isn't even necessary to lose weight (though good for you!), all you need to do is portion size and eat a balanced diet, make sure you're in calorie deficit (you can use a calculator like this to find out the right amount -
https://www.calculator.net/calorie-calculator.html), you don't need to be extreme, don't deprive yourself of things because it won't be sustainable, just make sure you stick to portion sizes. So have meals that are at least half fruit and veggies with some protein (like meat or vegetarian protein) and some carbs like rice, make sure it is low calorie and I recommend trying to stick to whole foods not processed foods, then have a "snack calorie allowance" left over from whatever your meals add up to that you can eat whatever you want from, just make a habit of reading calories and roughly calculating how much a portion is but don't ever deprive yourself of what you like, and you don't have to be too strict, as long as you stick to this for most of the week you'll lose weight, and it's sustainable in the long term because it's a balanced healthy diet and you can have whatever you like. Just watch out for "hidden" calories like whole milk and rice, whole milk has a lot more calories than people realise and if you drink a lot of it a day it may be part of the issue, you can switch to skimmed milk or an alternative to cut calories if you drink a lot!
You can make it fun by eating like a kiddo, both because of portion sizes (making sure it's the right amount like a caregiver would for their Little) and with fun plates, food shapes and things, imagine your CG making sure you eat well with the right portions
I lost around 17kg just by doing this (from around 60kg to 43kg - I'm only 5ft so though I need to put on 2kg or so because I keep losing weight still without trying because I haven't got the hang of maintaining instead of losing, my weight is still (only just right now) healthy for my height), I refuse to deprive myself of any foods, I like to be able to eat what I like when I like, I don't do diets, but I really like feeling healthy and having lots of vitamins and things that will help my body, so I feel really good eating healthy too, it'll make you feel so much better in yourself
