The on-going trend that needs to stop immediately is consumption of bulletproof coffee. Bulletproof coffee is a brand name, and also a high-calorie, high-fat drink that people make at home; it’s just butter and/or coconut oil, added to coffee. People claim that the butter-coffee combination gives them energy.
Butter is mostly fat, and fat is one of the three macronutrients, like protein and carbs, that have calories that are converted into energy, once consumed and broken down. In other words, any type of food = energy.
Saturated fats and oils should be limited, and saturated fats from animal sources lead to higher cholesterol levels. If your body craves fat first thing in the morning, grab a handful of nuts, or blend some almond butter in your coffee, or, better yet, eat a real breakfast with fiber, that contains nutrients.
