What is the negative calorie diet?

The negative calorie diet refers to the concept that certain foods require more energy for the body to digest, absorb, and metabolize than the calories they provide. This is often attributed to foods that are low in calories but high in fiber and water content, such as fruits and vegetables. These foods can indeed promote weight loss since the body burns more calories processing them than what is consumed.

By emphasizing these specific kinds of foods, the diet encourages individuals to eat a higher volume of low-calorie items, leading to satiety without a surplus of caloric intake. This aligns well with the principles of a healthy diet, which highlights the benefits of high-fiber and nutrient-dense foods that support overall health while promoting weight control.

In contrast, a diet high in sugars and fats would not fit the paradigm of a negative calorie diet since such foods are calorie-dense and often lead to positive caloric balance rather than creating a deficit. Similarly, a diet focused on high-calorie foods or a typical calorie-restricted diet does not highlight the unique characteristic of requiring more energy for digestion compared to the consumed calories.
