Keto diet observation and question

The ONLY thing that I find difficult about Keto is eating enough fat without overdoing it on the protein. Unless I really, really try hard, I eat more of the latter than the former every day. And I know that isn't good.
Any thoughts from you who have done this successfully?
I know all about fat bombs and bullet proof coffee, but If I add those to my diet, my calories sky rocket and at 67, too many calories is NOT a good thing. I know by eating sardines for supper, I can keep the protein and fat more in line, but dayum, that gets old quickly.
I also don't do the heavy cream thing for the same reason(as much as I love it). The calories outweigh the benefits.
Thanks for any insights.
