Betty for decent weight gain calories need to closer to 3000 a day, keep pushing portion sizes and adding calories every which way you can.
Moom I'm not surprised they've said that tbh, I think you have to use school as leverage and say once you're eating and healthy we can get you back to school. My dds plan is tweaked slightly from a normal 3 plus 3 plan as we lost snacks last Christmas so I focused on getting calories in during the meals. My dd has;
Porridge made with double cream and ff milk, a large portion and I estimate around 700 calories. Small glass of smoothie to drink.
Lunch a tuna Mayo baguette with lots of butter, a bag of crisps, a small cake or a small yogurt and a glass of juice to drink. Again around 700 calories in total.
Afternoon snack is a cereal bar.
Dinner is a large portion of whatever is on the menu, common meals here are jacket potatoes with beans and cheese (I add butter to beans snd scoop out the potato from another JP to add to her one). Pasta with pesto and garlic bread, salmon in a cheese sauce with pasta and veg, pizza with chips and salad, veggie burgers with chips and salad, fishpie (can add double cream and butter to the mash) with veg. I aim for 800-1000 calories for dinner.
Pudding, large portion of various high calorie puddings, common ones here are tiramisu with double cream, sponge puddings with double cream, milkshakes made with ice cream and double cream, pancakes with fruit and ice cream, rice pudding with added double cream...
I aim for 500-700 calories.
I get through a lot of double cream 😉
She has gained weight on this plan so I've not pushed the morning snack or evening snacks.
