newbie
How much fat am I aiming to eat? Is there a minimum or maximum? I am not the best person to answer this but hopefully someone else might be able to give you actual figures but you should eat fat:protein:carbs. If you eat things from the 'allowed list' on the spreadsheet (BIWI will post a link to the new spreadsheet when BC starts but [[https://docs.google.com/spreadsheets/d/1GQAVKe1likhhEQDspQEHy4l0sILl0N80fTO53I4t6ns/edit#gid=0]] is the old one. The various tabs at the bottom should give you some more advice and also other sources to look at for information on LCing.
Same with protein? You don't want to go too high with protein as too much is not good for you, again I don't know exact weights.
And Carbs? Is there a Max i need to stay within? Miffy mentioned between 50-100 due to my thyroid issues, but I'm going to go for that, as she suggested after bootcamp, so in bootcamp, is it 20g carbs? I hit 35 yesterday, so not sure if that's too much. Carbwise don't worry too much, eat according to the list and you won't go far wrong. I have no idea how many carbs I eat but some days will be lower than others. I think 35g is fine, I am afraid that I don't know much about thyroid issues but others like miffy do so take their advice on that.
How much do you have to lose (if you don't mind me asking?) if you have a lot then you definitely will not need to worry about being too precise with grams of carbs, fat, protein etc. Some people find as they get nearer to goal they need to start adjusting this. I think stunt and pisses would be good for advice on this.
Is a Bullet Proof coffee made with 1 teaspoon of butter and coconut oil or 1 Tablespoon? You can make it with slightly different amounts of butter/oil/cream. I don't measure but just add a bit of each and blend it well. Some people hate them so don't start with loads of oil/butter at once. Coffee with cream is lovely 
Someone just mentioned a frittata made for a few days. How do you keep things like that in the fridge? Do they not get soggy bottomed? Sorry, not sure, I only keep frittata for two days in the fridge. It is fine like that.
Hope that helps 
You will also find that once BC starts most people will post their daily meals. It can be very useful and give you ideas for later on in the week. I would say though, don't worry if it seems that some people are eating much less than you are. It is not a competition to eat less and one really good side effect of Lcing is that you appetite reduces so those of us who are long term LCers will be eating less than new starts. With LC you eat when you are hungry
