Are High-Protein, Low-Carb Diets Effective?
High-protein, low-carb diets have been around for a long time, and it's easy to see why. Many people do lose weight, probably because the extra protein makes them feel fuller, and this allows them to consume fewer calories. What about long-term results? In a clinical study that looked at this question, these diets didn't seem to be any more effective than plans that simply restrict calories.
The main premise behind these diets is that as long as you restrict carbohydrates, you can eat as much as you want and still lose weight. Because high amounts of protein can help suppress the appetite, many people may lose weight with this particular diet plan.
During ketosis, the body switches from carbohydrate burning to fat burning. When the fat in the body becomes the primary source of energy, the person can lose weight. Although ketosis can be potentially serious if ketone levels become too high, this condition can cause a person to feel less hungry and eat less than they otherwise might.
