Is there actually such a thing as a ‘fat burning’ or ‘negative calorie’ food? I’ll talk about exactly what a fat burning food is and if you can actually use this principle to reach your weight loss goals.
A fat burning food is loosely defined as a food that ultilizes more energy being processed by the body than it does contain energy in itself. Foods that are high in protein and fiber are the type of foods that would theoretically fall into this category, as protein and fiber take more energy to process by the body than do foods coming primarily from carbohydrate or fat. Some spicy foods could fit into this category, too, as they contain a substance called capsaicin that could elevate your metabolic rate slightly.
So is it enough to make a difference? In short, no. The difference is so small that you’re much better off focusing on the basics – like controlling your portion sizes, balancing your foods the right way, and eating multiple small meals throughout the day.
