Researchers have found that a diet rich in protein is more effective at preventing hunger pangs than diets rich in carbs and fats. The study revealed that protein suppresses hunger by regulating the secretion of a hunger-producing hormone called ghrelin, which is secreted in the stomach to stimulate hunger. When protein is consumed, the body secretes less ghrelin, which otherwise produces feelings of hunger. Fat was found to be the least effective in suppressing hunger. The take-away here is that it's important to eat a well balanced diet at every meal, consisting of real food rich in protein but also good fats and carbohydrates. Eating only protein or too much of it is not the answer to losing weight -- eating a healthy balanced diet and exercising everyday is. Both fat and carbohydrates are essential for other bodily functions.
