In which food group are negative calorie foods typically found?

Negative calorie foods are mainly identified among fruits and vegetables. The concept of negative calorie foods refers to items that require more energy for digestion, absorption, and metabolism than the calories they provide. This phenomenon primarily applies to foods that are low in calories and high in water and fiber, such as many fruits and leafy vegetables.

Fruits and vegetables like celery, cucumber, and certain berries are examples often cited in discussions about negative calorie foods. These foods are not only low in calories but also packed with nutrients, allowing the body to burn calories while processing them. This unique characteristic makes the fruits and vegetables group the primary source of negative calorie foods, distinguishing them from grains, meats, dairy, nuts, and seeds, which generally contain higher calorie content and do not exhibit the same negative calorie effect.
