I only drink water and black coffee, but have heard that a small amount of fat is OK too since its impact on insulin levels is limited.

I think the general rule of thumb is anything under 50 Calories is considered fasting. Maybe change to a teaspoon instead of a tablespoon?

I have replaced my coffee with hot water. After a few days it stopped bothering me and I used to go through a lot of coffee every day.

That would be a "bulletproof" or "fat fast" with the coconut oil. I can't imagine it would hinder any possible weight loss or progress on reversing insulin resistance if that's at all an issue. It won't trigger an insulin response so, it will mimic a fasted state for all intensive purposes. It will also boost ketones and may make fasting more possible to stick with without fighting hunger.

That's so funny because I was wondering the same thing this morning!
I've only had coffee with heavy cream since 3pm yesterday. Well Keto-aide too but... I gotta have that! I was wondering if I could make it through the rest of the day with coffee and heavy cream and consider that a coffee fast? Lol.
Hey! While I'm sick I might as well take advantage in f this whole stomach only wants this momentum!!

The proteins and sugar in the cream may have a bigger effect on a fasted state than other fats like butter or coconut oil. So, if you want to mimic a fasted state as much as possible, avoid the cream.

Do you have to fast when your on keto diet?

Nope. Not at all

I too was wondering about the bpc and fasting too... I find that if I have my bpc coffee in the am I do no eat the rest of the day until about 4-5pm. I have dinner and sometimes a snack and then I am good for the night. The BPC really fills me up and then sometimes I will have another coffee at work black or chicken broth around lunch time.

There was a guy in a video a few months ago that got posted that supported adding fat if it made doing IF easier I remember. There is another IF active tread running currently and there sure are a lot of different ideas about what is IF and how it works I realized.

That's how I always do IF. I need the fatty coffee in the morning for appetite and also for ADHD.

Almost all of the top guru people I listen to on podcasts about Keto/IMF have a cup of coffee with butter and MCT oil (usually Bulletproof Brain Octane) - and consider it "extending the fast".

I don't think normal coconut oil contains the same properties as MCT oil that actually helps produce more keytones in your blood which amps up your fat burning abilities.

Personally I'm not a coffee person. So I drink a cup of green or oolong tea in the morning with Brain Octane in it. Frothing in the butter into the tea like you are supposed to didn't settle well in my stomach for some reason but I could eat it fine. No idea....I pretty much go without butter in the morning these days and am having success on the scale and with hunger control.
