Fat bombs refer to high-fat, low-carbohydrate foods that are typically consumed before bedtime or during a fasting period. These types of foods can include items such as nut butter sandwiches, bulletproof coffee with coconut oil and grass-fed butter, avocado toast, or even a cheese and meat plate. The purpose of consuming fat bombs is to provide the body with essential fats that it needs for optimal functioning while also promoting satiety and reducing cravings for sweets. Fat bombs are often used in ketogenic diets as they help maintain nutritional ketosis, which involves getting most of your energy from fat instead of carbohydrates.
