Ally, please don't be scared. As long as you are low carb, increased fats will not make you fat, and may even improve your cholesterol levels. It is only when high fats are combined with high carbs that you gain weight. Look at my own statistics on low carb/higher fat:
I have lost 4 stones, am at my target weight and still struggling a bit not to lose any more.
My cholesterol levels have all improved on each of the 6 tests I've had this year and are excellent.
I eat butter and use it to cook mushrooms etc. and put some on my veggies
I eat mounds and mounds of cheese
I eat full fat Greek yogurts
I eat real mayonnaise
I use double cream in my coffee
I use rapeseed oil for frying
I don't like olive oil or I would add that to my salads.
I am not alone with these statistics, and I am never hungry because fats fill you up.
