Hi - I am now on the pureed phase and am averaging 500-600 cals per day. I am loosing 1-2 lbs per day, which seems a little excessive.

I would like to moderately up my fat intake with good fats. I do not like avocados which would be the easiest approach. Any other thoughts to up fat content (I am mostly eating plant-based protein shakes, pureed lentil soups and broths). I love eggs, but I tried a soft scrambled egg, ate half, and immediately vomited, I think it is just too soon for eggs.

Thanks for your advice/recommendations!

If you are getting your protein in, I wouldn't modify anything. The amount of time you are going to lose 1-2 lbs a day is going to be pretty short. Take advantage of it.
