Do you use an immersion or emulsion blender when making your bulletproof coffee? I use a cheap little stick blender (milk frother) I bought off Amazon and give it a good whisk when first blending it all together and then again a bit later if the oils float to the top and make a skin.
Here's my recipe: a scoop of collagen peptides, heavy whipping cream, MCT oil, Kerrygold butter or ghee and coffee. Sometimes a little Himalayan salt and cinnamon.

half and half with skinny syrup

I use organic heavy whipping cream. It's loads more expensive but has a better Omega 3 profile than regular cream.

I just have my coffee with heavy cream and liquid stevia.. just a splash (1tbsp) of cream is 50 calories. Keeps me in fasting mode until I get hungry for food. I’ve got plenty of good useable fat on my body if needed for energy, I don’t need to add extra fat in the AM. Not saying I don’t consume fat during the day to help with satiety and cravings but not everyone needs bulletproof coffee and fat bombs all day everyday. 🤷🏼‍♀️🤗

I do black tea with Sugar free coffemate and unsweetened almond milk in the mornings. We all have to chose what works best for us. 3g of carbs in my morning tea is worth it for me, maybe not for someone else. But still really doable in keto. I tend to aim for 15-25 net carbs per day so maybe a little easier for me.

Sugar-Free Coffeemate. Tried dozens of other things but I didn’t like them as well. I still can easily stay under 20 net carbs per day and I don’t seem to see anything negative from a few TBSP per day.
