EndlessDream is right. Skipping breakfast and lunch can result in stomach ulcers and sudden weight gain (had personal experience...), ESPECIALLY skipping breakfast!
You have to incorporate exercise in your daily routine. Stomach and body fat is mostly caused by lack of exercise, and maybe that means you need to do toning exercises. Try doing simple exercise videos like the 3-mile powerwalk on YouTube (trust me, I sweat like crazy when I do those workouts). Anything that gets you sweating, is the kind of exercise you need to do. I hated working out when I first started my weight loss journey too. I would always start wheezing every time I started working out. But after pushing through everyday, I think working out is one of the best stress busters I've ever had!
If you want to lower your appetite though, I suggest eating a full lunch and breakfast and skipping your dinner. If you can't skip dinner, then at least try aiming for an early dinner, around 5:30 or 6:00. Your body needs time to digest at least 4 hours before you sleep. I started gaining weight around puberty when I was 12, it could be the same for you too.
But honestly, there's nothing wrong with having consciousness about your weight. Now starving yourself and dieting is BAD, but there's nothing wrong with changing your lifestyle in order to be fit. It's a good thing that kids start caring about their health, and the earlier you start, the better off you are.

You need breakfast and lunch. Starving yourself, even if you aren't hungry, makes you loose energy to the point you could pass out from not eating. Keep your diet healthy. For breakfast, at least have yogurt, fruit, and juice. Drink at least 4 full glasses of water a day. Trim down on the snacks. Everyone has different bodies and build. You may just be large-boned. And that's not bad! That makes you stronger and higher ability to gain muscle. Loosing weight doesn't happen over night. It can take months.
For years my parents would tell me I'm skinny but compared to other people, my waist was bigger and I would always hide it. Though it was obvious I weighed more, I've only been doing this for a week and I didn't ever tell anyone what I was doing until my parents found out. I would skip lunch and breakfast and say I was full. I only ate a big dinner every night. Once my parents found out, they said it was unhealthy and if I didn't stop, I would develop an eating disorder. I obviously listened to them, but I've tried as best as I can so far. I have barely lost any weight from exercise and my parents won't let me go on a diet because I already 'eat healthy enough'. I want to lose weight without exercising being 3/4s of my lifestyle. I know, I'm a lazy idiot for saying all this.
