New research is shedding some light on why people can lose weight so fast on low-carb diets.
The study at Temple University finds the bottom line is calories. When you look at what the low-carb diet means, taking away your carbohydrates which include potatoes, bread, pasta then, it's easy to see you're putting yourself on a diet that removes a lot of calories.
"At the end of the day, it depends on how many calories you have eaten and how many calories you have spent through activity. But the study taught us that it's the carbohydrates that stimulate the appetite and therefore, if you eat more carbohydrates, you're going to have a greater intake of calories," says Dr. Guenther Boden, with the Temple University School of Medicine.
Researchers say it's too early to understand the long term effects of a low-carb diet, but at this point, their findings underscore the theory that weight loss is as simple as cutting down on the calories you take in and increasing the calories you burn off.
