Struggling to meet fats

So me and my diet buddy are on different diets, myself aiming for keto, they're on the carnivore diet. Similar enough, you'd think, high fat, high protein, low carb. But I'm finding myself struggling to meet the fat requirements and going over on protein. Im no nutritionist and I was hoping to know if anyone knew some very high fat foods to keep up. I can't have nuts, and avacodos are not my cup of tea, so I've been focusing on milk/meat fats. Idk. Any advice is appreciated. I'm only 5 days in on the diet and I'd like to make sure I'm correcting any issues before it becomes a habit. I'd rather not eat an entire stick of butter LOL
