How much is a lot? If you are just eating a serving a day you should be fine. Try to stick with the low fat cheeses if your worried about the extra calories. And it also depends on what your goals are.
My brother eats a lot more cheese than I do and he is way leaner than me. I don't know if it would affect contest prep conditioning (never experienced it first hand), but for regular people, cheese is good.
If you're on a low carb diet, you shouldn't be eating low fat cheese. The fat in cheese can be utilized as energy.
OP, I've been on and have had success with all different types of low carb diets, most recently a strict keto. Cheese is always a staple of my low carb diets, it's high in fat and protein, both of which one needs when going very low carb.
does not matter...cheese is an excellent source of protein. higher than average sodium is about the only thing that is of concern and even that is nit-picking unless you are in contest prep.
you don't need fat...you need a deficit and depending on your particular hormonal response to different foods and your will power, fat may provide an easier to handle cut (satiety etc) but in the end, all you really need is a deficit.
I never said to replace carbohydrate calories with those from fat. I simply am under the impression that while on a already kcal restricted diet, a higher amount of fat would equal an even lower amount of carbohydrates, assuming protein stays the same. If the OP needs X grams of fat a day, why not use cheese as a source?
speaking only from my own experience, I always found keeping cheese to 1-2 servings/day max when dieting helped, even with relatively constant macros. I'd rather eat some tuna/almonds anyways. Honestly though its probably not a big deal. Dont go crazy on the cheese, keep a good deficit, and bust your ass in the gym and you'll be fine.
