Sotired i would try and sneak calories in where you can so if your dd will eat toast make sure you buy thick cut bread, I buy think cut loaves from Aldi and they are 140 calories a slice. Add butter and then peanut butter, make sure you're buying full fat yogurt and check you're buying the highest fat/calorie content one!
Got the beef stir fry add avocado oil as it's loads of calories, would your dd agree to porridge for breakfast? You can make that with double cream.
The lack of food definitely brings on depression and anxiety, the brain is particularly vulnerable to weight loss and it needs a lot of fat to function properly.
My dd only eats 3 times a day at the moment so I'm concentrating on getting as much packed into those 3 meals as possible. For example today she had porridge with double cream approx 500 calories, a small amount of smoothie around 50-75 calories.
Lunch was scrambled eggs on toast, I used duck eggs (as advised by someone on this thread!) 2 slices of thick toast, lots of butter and cream in the eggs and ketchup as well. I'd guess around 600 calories, she had a small amount of oj and yogurt with it around 80 calories worth.
Dinner was pesto pasta with tuna, cheese and garlic bread. I added avocado oil to the pasta, I'm guesstimating around 750 calories. Pudding was home made rice pudding made with double cream and ff milk again I would guess but around 300 calories.
So in total about 2300 calories ish, ideally she'd be having snacks to get it up to 3000 calories which is the ideal for weight gain but we're not quite there yet!!
