2. Zero-calorie vegetables (zucchini, celery, cucumbers, cabbage and broccoli)

The so-called ‘zero-calorie foods’ are foods that require more energy to break down and digest than they provided. However, having fewer calories doesn’t mean fewer nutrients. Because they are mostly made up of fiber and water, they are naturally low in calories. The best part is that you can eat them in large quantities and feel full longer. Eating zero-calorie foods will prevent you from eating high calorie snacks, which is surely a win!
