Well I’d say of course having 3 meals plus snacks - always have them around.
Drinking calories, soda smoothies milkshakes, iced coffee
1. Cream it’s easy and cheap and you can add it to you coffee shakes etc.
2. Always combine carbs with fat 😉
Mac and cheese, pizza but really everything. Fat is high in calories so try to get that up.
3. It a little controversial but alcohol is def making u fat. You get hungry and it’s very high in calories.
If you have like a aperol Spritz and two beers with the dinner that’s like an easy 800 calories plus.
If she is really on board just let her have 2 shakes a day on top of her normal (eating what she wants) diet .
500ml full fat milk 300
100ml cream 300
60g maltodextrin 200
60g protein powder 200
With some ice blend it easy 1000 caloires.
With her hopefully not moving to much she only needs to eat around 1000-1500 calories to maintain.
So having a good breakfast and a shake should result in her eating everything after that directly on to her hips
