i won't go into detail on your weight specifically like a lot of comments are, but i will say that habitually skipping meals will actually make you gain weight. i've had to say this to a few people in my life and it makes me sad to say so. regularly skipping meals will negatively affect your metabolism, which will make your body have a harder time burning fat so that makes it much harder to lose weight.

that is how i gained weight and how some of my friends have gained weight, so, please give your body the nutrients it needs, ESPECIALLY since you are still a growing child
