Could try adding in liquid calories like whole milk. Or adding a few servings of nut butters / oils to your meals. If you're having trouble consuming more calories, depending on what your macro's currently look like, I would lean into fats a little more maybe.
I have never had any luck with this
Fats made me hit calorie goals, but they slowed down digestion so much that I could check BG throughout the day and I'd never come back close to fasted levels where I'm ready to receive the next meal. It absolutely ruined my nutrient partitioning.
When I limited the fats, meals would pass in 2-3 hours and I'd be ready for the next. Figuring this out with food was honestly like finding steroids all over again haha. Once I figured out the nutrient partitioning aspect and ate accordingly, I just started blowing up like it was my first cycle all over again.
Not saying your wrong or anything, I'm sure what happened to me and how my body used food will not hold true to the same for everybody. Just sharing my experience for people reading, to keep in mind the other possibility/end of it is all.
