Best healthy foods for weight loss and fat burning! This collection of the best zero calorie foods for weight loss and fat burning will give you the inspiration to get fit and get into shape. Zero calorie food for weight loss? Yes, you read that right, no calories. Zip. Zero. Zilch. And no, you don’t need to eat only salad.

How can a food be zero calories?

Well, the basic premise of a zero-calorie food is that your body will end up burning more calories while you are eating the food than the food you’re eating contains. In other words, the ‘calories burned’ is greater than the amount of calories in the food.

If you’re interested in a bit more of the science stuff, the process your body undergoes while it heats itself up is called thermogenesis. And your body does this when eating these foods. It heats up and starts burning calories. In this case, it burns more calories than are going in. 

Do these foods really contain zero calories?

Not necessarily, but because your body burns more than it intakes, it’s considered a negative or break-even point. This allows you to eat these foods and fill yourself up, and your body will burn those calories plus more.

Our list of zero-calorie food is ordered by how easy they are to pack in a lunch to school, work, or on the road.
