Everyone who has ever followed a diet has heard of "negative calorie" foods that you can eat abundantly while still losing weight. But is it really that simple? Fitness trainer Viktor Mandziak on Instagram discusses what you need to know about "negative calorie" foods.

What to know about "negative calorie' foods"?

"Celery is considered the queen of negative calorie foods. Looking at its nutritional composition, you can be amazed by what you see - only 13 kcal/100 g and it also contains fiber. It's a mega-dietary product," says the trainer.

Mandziak explains whether celery can burn more calories than it provides to the body.

"Specific dynamic action of food (SDAF) - the amount of energy expended by the body to digest a product. It is said that there are foods with an SDAF of less than 100%. That is, celery, grapefruit, tomatoes, and cucumbers supposedly expend more calories to digest than they provide to the body," says the expert.

He adds that scientists conducted studies on lizards, forcing them to eat celery and similar products, and then measured metabolism. They came to the following conclusions:

  • celery - 41.8%
  • broccoli - 37.5%
  • apple - 35%
  • carrot - 37.6%
  • grapefruit - 34.1%
  • tomato - 36.9%
  • cucumber - 36.7%

So, do "negative-calorie" foods exist?

"We see that these products burn a lot of calories, but nowhere do we see a figure of 100%. So the fairy tale about 'negative calorie' foods from 'healthy eating' experts did not stand the test," Mandziak emphasizes.

The trainer also notes that the idea of negative calorie foods itself is absurd because food is supposed to enrich the body with calories, not take them away.
