Many believe in 'negative calorie' foods, but that's a myth. Calories measure the energy in food, so no food has negative calories. However, certain foods are so low in calories that your body burns more energy digesting them than they provide—earning them the nickname 'zero-calorie' foods.
These nutrient-dense options are ideal for weight loss, as they promote fullness, boost metabolism, and minimize calorie intake without sacrificing nutrition.
Our expert guide highlights the best 'zero-calorie' foods to help you slim down effortlessly.
