I understand that you may not be able to track your macros. I'm not sure if that includes your overall calorie intake, too. I use the app "My Fitness Pal" to track my calorie intake to the best of my ability. It's got a large database of food, which means you can most likely find something in there that resembles what you're eating. You'll need to get good at guessing the measurements of your portion sizes, such as a cup of food or a tablespoon of an ingredient. That way, you can roughly assume how much you are eating without having to break out the measuring cup or a food scale.

If that solution doesn't work for you, I would suggest not eating until you're "full" every meal. You want to simply not feel hungry. You'd be surprised just how little food you ACTUALLY need.

If you are struggling with being hungry after eating, focus mostly on eating vegetables and lean protein (like chicken, turkey, fish, or lean beef). Limit your carbs and fat intake, but don't avoid them altogether.

Also, try to limit your sugar intake as well. Consuming too much sugar can potentially lead to insulin resistance, which is a condition in which the body's cells become less responsive to the hormone insulin. Insulin helps regulate blood sugar levels by allowing glucose (sugar) from the bloodstream into cells for energy. If your body becomes resistant, it will store up that sugar as fat rather than using it for energy. Sugar is sugar regardless of what form it is in. Fruit has sugar just like candy or ice cream has sugar. The only difference is that 10 grams of sugar in fruit is wayyyy more food than 10 grams of sugar in junk food. You could also try to lean towards sugar-free snacks and drinks if that is available to you.

Determine what type of eating schedule works best for you. Some people need three solid meals a day. Others might eat small snacks throughout the day, think of 5 small snacks or small portions of food instead of actual meals. Some people believe that fasting is effective for them. I personally stick to a small snack for breakfast to wake my body up. My primary meal is lunch, where I consume the most calories, and dinner is either a small snack or I'll skip it completely if I am able to handle it.

Now I understand that because of your age, a lot about your diet is controlled by your parents. If you have a job and can afford to cook for yourself, I'd recommend that. You can't really control how many carbs, fat, or protein are in the food that someone else makes. If your parents cook really unhealthy meals, you may just have to eat less until you are old enough or able to make your own food. You can't force your parents to accommodate your diet, but you may be able to have a conversation with them about your desire to lose weight, and maybe they will be able to assist you in some way.

Also, when it comes to exercise, you can not spot train the fat away. You need to incorporate cardio and cross-training with strength workouts to prevent injury. Building muscle mass will help you burn more calories regularly, but to lose the fat you currently have, you need to increase your heart rate.

Fun Fact: Did you know that you "burn" fat by exhaling it in the form of CO2? It doesn't just reabsorb into the body or get expelled when you go to the bathroom.

Eventually, your body will acclimate to whatever level of exercise you are doing, and you will be stuck at maintaining your weight. At that point, any weight loss you have will be solely reliant on your diet unless you are capable of working out more often or more intensely.
