Hacking your morning coffee with butter and coconut oil will keep hunger at bay, reduce caffeine jitters, and provide sustained energy while intermittent fasting. Beyond intermittent fasting, there are many reasons to consider hacking your morning coffee, and butter and coconut oil are not the only options—collagen, MCT oil, and spices such as cinnamon, cardamom, and/or turmeric are all excellent additions. Consider collagen for bones, skin, hair and nails; MCT oil for energy production; and/or cinnamon to support blood sugar balance.
