Can I drink this Hawaiian keto mac nut coffee while intermittent fasting?

Yes, you can, if you're doing a fat-fueled fast (which is common in the keto diet world). This coffee has zero sugar and plenty of healthy fats from butter and MCT oil, which can help you stay full and energized. But if you're doing a strict fast (no calories), skip the fats and stick to black coffee.

What’s the best macadamia nut milk to use for keto coffee drinks at home?

Go for an unsweetened version with no added sugars or weird thickeners. Brands like Milkadamia or Califia Farms often have clean ingredients. Just check the label, some brands sneak in hidden carbs that can throw off your low carb coffee game.

Can I make a batch of this keto iced coffee in advance?

Definitely. Brew a few servings of coffee ahead, mix in the macadamia nut milk, fats, and sweetener, then store it in a sealed mason jar in the fridge. When you're ready, just shake it up or blend it again before pouring over ice. It’s perfect for a grab-and-go low carb coffee on busy mornings.
