I only looked at one day of your diary, but I noticed a lot of carbs coming from those Keto muffins. May I ask what is in them, as it seems high carb for a low carb diet plan. Looks like you're eating healthy, but still higher carb. Have you tried adjusting your macros for a more keto friendly approach?
Usually about 80% fat, 15% protein, and 5% carbs. This may help you out to see where each of your macros are being hit or not hit.
Also, not sure if you're tracking water or not ( I do rarely on MFP) but you should get like 100oz of that a day.
I too am new and struggling. A lot of the Keto peeps here are so great though. Hope you make it!!

I have been eating nuts like a madwoman. I realized that my favorite ones are high in carbs (cashews), so once I finish eating them (I'm not wasting food no matter what!) I'm going to stick to Macadamia nuts, as they are one of the lowest carb nuts. Almonds are good because the carbs are mainly fiber, which is a net carb (OK to have, needed for digestion etc). I ate a ton of peanuts and hazlenuts this weekend, like a whole bag of them. Each. oops.

I am interested in finding out how dairy fits into people's keto world.
I love cheese, milk, etc and it's low carb and high fat, however, it's got lactose in it (natural milk sugars). I have read that some people do not do well with dairy on Keto because of this. I know that any dairy you do consume should be full fat (I've never been one to drink whole milk, and now I love it, so rich and yummy).

Hopefully someone can give a better answer to the nuts on keto thing!
UPDATE: Just found this, may help: Nuts are also a good source of fat and other nutrients. However when it comes to nuts it is important to remember that not all nuts are not good as keto food. Some examples of good nuts to eat are Brazil nuts which have a low amount of carbs and Brazil nuts also contains a high amount of selenium. Macadamia nuts have a very high amount of fat and contain iron and B vitamins. Hazelnuts contains a lot of vitamin E and they also only contain 3.4% carbohydrates. Almonds contains a lot of vitamin E, iron, zinc and calcium. They however contain about 6% carbohydrates which is a little high percentage.

Remember that Peanuts are not a nut but a legume. It has a high carbohydrate percentage at 10% so you should try to avoid peanuts. Cashew nuts are also very high in carbohydrates with a 18.7 percentage so also try to avoid the Cashew nuts.

This was from a site called www.dietketo.com. Have never seen the site before, not sure how reliable it is, but I mean, it's pretty basic.

You can eat both nuts and cheese in moderation. Milk has a lot of sugar and should be avoided. Eva I noticed your diary settings have not been changed to reflect a keto diet, to do this go to My Home > Goals > Change Goals Button > select the Custom radio button > Continue > then change the percentages of fat protein and carbs to what you want. I use 10% Carb 25% protein 65% Fat.
