@csaliba You have to start tracking your macros. There are tons of apps for it. You have a set amount of calories you need per day to just live and stay the same weight. You need to eat less than that to start loosing the weight. If the deficit is smaller and you exercise it will be just fat, if it is bigger it will be muscle too. The body will basically dissemble the fat or muscle(or both) to get the energy it needs. That’s how you get rid of the fat.
https://tdeecalculator.net/ use this to learn how much you need per day and then eat around 500 calorie less than that.
Now the main 3 thing you eat are proteins, carbs and fats. Both protein and carbs have 4 calories per gram and fat has 9. Ideally you want around one gram of protein per pound of weight you want to be. I don’t know your weight but usually you want between 60 to 100 grams of fats. You can adjust the amount of carbs to that.
If you just want to loose weight just stick to the one gram per pound and mainly the deficit. If you want to start working out later you can read up more about it.
You can’t really avoid being hungry. Your body also won’t have enough energy so you might also be tired and sleepy. That’s usually where people fail. You need to have the will to overcome the hunger and don’t eat. Of course you might sometimes fail and eat a bit more than you should. It isn’t the end of the world. At least if you overeat, make it be on apples not ice cream.
Also cardio can be good for you. Try running or cycling. If you can’t do that, walk or swim. Find something you enjoy.
It will take quite a bit of time but if you push through you will start seeing the results.
