Consuming enough protein - actually just enough calories in general will likely be a problem. Lots of Christine's posts mention her milkshakes. I made myself one or two of those every day & added a scoop of whey protein powder. It's a diet fairly heavy in dairy & I'd do my best to make those milkshakes taste differently. I'd add coconut milk, or various fruits, etc. But my favourite and most calorie-laden ones were chocolate and peanut butter. Some days I would just not feel like having dairy, so I'd just have a couple of drinks of protein powder mixed in a shaker cup with plain water, then have some soup & a glass of green juice. Eventually you'll heal well enough to be able to eat softer, more solid foods. If you're an egg fan, then it'll be easier to meet your daily protein needs.
