Hi Adam! welcome to Traineo
It's very, very important, especially at your age, to be sure to be getting all the nutrition that you need. You might feel that you should be eating less, but you are very likely just eating the wrong types of things, and not enough of the right!
I've got my "mom" hat on, ("mum" if you are british), and let me give you some friendly pointers
No soda pop (lemonade)
No candy/sweets/biscuits
Cut back on the butter and cream
Use a little bit of sauces, just a taste. Food doesn't need to be drowned!
Eat lots of fresh, raw veggies. The more colorful, the better.
Eat fruit every day, but only 2 or 3 pieces (whole fruits, not juices)
Choose whole grain breads and cereals, like porridge, whenever possible.
A serving of meat (if you eat meat) should be the size of the palm of your hand... no more. It's about the size of a deck of regular playing cards.
Drink lots of water. Don't wait until you are thirsty! When you get up in the morning, have a glass, and have a glass before each meal.
Have fun! this is a lifetime adventure.
