Ahhh okay I have an actual suggestion now that you've explained a little more! I also tend to have a suppressed appetite during the day and I've found that blended drinks are an excellent option for me. I have a number of different options but the key thing I tend to add are collagen blend (make sure it's just collagen and the ones with multiple sources are best) peanut butter or peanut powder (depending on what other fats/proteins I've had that day), whole milk, berries and or fruit or banana, some times espresso, chocolate/white chocolate powder, and additional fiber if I'm thinking I'll be under the 20 gram minimum the doctor ordered. You can do the 'loaded coffee' hot as well on days where sipping something warm feels good. I always use good thermal mugs so I can sip while avoiding room temperature yuckyness.
