Negative Calorie Food: Theoretically Possible, But Not Yet Proven

Healthwire Bureau

New Delhi, January 25-There is a flood on the internet with lists of negative-calorie foods. People are talking and tweeting about it. So what is a Negative Calorie food?

Negative-Calorie Food

According to Donald Hensrud,Associate Professor, Consultant, Preventive Medicine, Internal Medicine, Lifestyle and Health Expert Minnesota (USA), those foods that provide us less calories and take more energy to digest.

There is a common misconception that there are some foods which you can keep having without the fear of adding extra calories in your body or gaining weight. While foods are vegetables and fruits may definitely make us feel healthy and strong from within, one thing everyone should be sure of, that no food falls in the category of no-calorie or negative-calorie food.

Out of many examples cited about negative-calorie food, one is celery, perhaps because it’s mainly water and fiber. Those pushing the negative-calorie narrative will say that you will burn more calories digesting celery than it contains, for a net loss. However, the reality is that throughout the day, about 5 to 10 percent of your total energy expenditure goes to digest and store the nutrients in the food you eat.

What this tells us that even celery and other non-starchy vegetables, which provide a small number of calories, still require energy to digest.

So, having a food which has a negative calories effect might be theoretical possibility but there are no reputable scientific studies to prove that certain foods have this effect.

Even non-starchy vegetables are not negative-calorie as they still have low-calories, and can make a smart choice to include in a predominantly plant-based diet.

The key to successful weight loss is adopting a healthy lifestyle that includes a balanced diet and regular exercise. You could be missing out on important nutrients if you follow extreme diets that promote eating only a few foods.
