When to eat and digest a food it is necessary to invest more calories than that food contributes, it is often said that it has "negative calories". This is the case of oranges, celery, tomato, asparagus and cucumber, among others. It is also estimated that a broccoli stalk, which can provide around 25 calories, consumes 80 calories from our body when ingested. However, the truth is that the concept of negative calories has not been scientifically proven, and at the moment nothing indicates that weight loss is achieved by eating these foods.
According to experts, the only scientifically proven strategy to obtain a "negative balance" in terms of calories is to eat a healthy and balanced diet and increase calorie consumption through physical exercise .
