I am also losing weight, so I have some experience. First of all, you should have a full breakfast. You can eat some coarse grains, such as whole wheat bread and a box of high-calcium and low-fat milk. You need to grow up now. Eat more vegetables at noon, but as long as you are seven points full, you can eat another apple. After dinner, you can exercise on the playground. Now in winter, you can make a snowman or something, but you should keep warm. Try to eat less at night. Eat grapefruit when you are hungry, which is quite slimming. Don't sit down after dinner. You can take a walk at home or jump rope to lose weight and grow taller. I hope you can succeed.
