What are Negative Calorie Foods? How Do They Support Weight Loss?

In the realm of weight loss and nutrition, the concept of “negative calorie foods” has garnered attention and curiosity. The idea behind negative calorie foods is intriguing – that some foods require more energy for digestion and metabolism than the calories they provide. In this article, we will delve into what negative calorie foods are, explore examples of such foods, and discuss how they can potentially aid in weight loss.

What are Negative Calorie Foods (Zero Calorie Foods)?

Negative calorie foods, often referred to as “calorie-negative” or “zero-calorie” foods, are believed to possess a unique property where the energy expended during their digestion and metabolism surpasses the energy content they contribute.

The idea of negative calorie foods adds an interesting layer to the conversation about weight loss and nutrition.
