I work as a medical translator, and lately so many books have been published on the deleterious effect of the transformation and breaking of food. So 200 calories of rice, the grain, will not be processed by the body in the same way of a 200 cal mix of rice flour, rice starch, rice flour, rice oil and so on. Food activates a metabolic process and sadly industrial food manufacturing is causing massive damage to our health. Gluten is the perfect example. Gluten was hardly an issue when it was a natural part of wheat, then started the extraction and breaking of wheat into several parts and gluten became an ingredient on its own that was added to food to make it soft, elastic to such an extent that it is even added to meat such as ham and sausages. And now even non - coeliac people suffer indisposition with gluten.
What I am trying to say is go for real and whole food, a steak, a chicken breast, a pot of mussels, a piece of fish which hasn't been transformed in any way with any addition. Alternate with a pasta, a risotto, again homemade with whole ingredients.
I wouldn't add more sport, she already does a lot and it will make her hungrier. I have a swimmer in the house and he is starving after training, and he will have sometimes a crêpe or even 2 pieces. of (real) bread with a couple of dark chocolate cubes in it.
The human body is far too complex to be affected by the extra 30 calories a quarter of an apple brings, Eat the same 30 calories of dried and fried apple made into apple chips and glazed with sugar, your insulin will be through the roof and those 30 calories transform straight into fat.
Look into the diet of the whole family and try to get rid of all packages with more than 4 or 5 ingredients listed . So a bottle of passata with tomatoes, salt, oil and basil is fine, any thing added to that leave on the shelf. Read the nutrition table, and product with 5 gr of sugars /100 gr (not the carb, the sugar line) , leave on the shelf, any product which hasn't whole food, but words such as powder, extract, starch, ... leave on shelf, any food you wouldn't be able to do in your kitchen because your need an engineering degree and high pressure machines leave on shelf. I am a great cook, I even give cooking lessons here in Australia but I would never be able to prepare doritos according to the ingredients list:
Nacho Cheese Doritos ingredients (U.S.), in order of percent of product: whole corn, vegetable oil (corn, soybean, and/or sunflower oil), salt, cheddar cheese (milk, cheese cultures, salt, enzymes), maltodextrin, whey, monosodium glutamate, buttermilk solids, romano cheese (part skim cow's milk, cheese cultures, salt, enzymes), whey protein concentrate, onion powder, partially hydrogenated soybean and cottonseed oil, corn flour, disodium phosphate, lactose, natural and artificial flavor, dextrose, tomato powder, spices, lactic acid, artificial color (including Yellow 6, Yellow 5, Red 40), citric acid, sugar, garlic powder, red and green bell pepper powder, sodium caseinate, disodium inosinate, disodium guanylate, nonfat milk solids, whey protein isolate, corn syrup solids.[15]
Do your own chips, by peeling and slicing a potato. Don't use jar sauces, even the healthy organic ones.
You don't need to have a dish that has a name. Roast some veggies in the oven, prepare a juicy and savoury tomato salad, add a small chicken breast coated in herbs and you have a lovely meal for every one.
Eat real food, nice food, and by avoiding sauces but going crazy on fresh rosemary, basil, chives, sage, and adding some lovely soups for dinner, you will not only take care of your daughter's weight but enhance her health as well.
