Eat enough protein, stay slim

Melbourne: Want to stay slim? Make sure that you eat enough protein in your diet, rather than simply cutting calories, says a new study.  Researchers at the University of Sydney have carried out the study and found that low protein in diets can lead to excessive energy intake and drive people to eat more snacks, the `PLoS ONE` journal reported.
On the contrary, they have found that enough protein in their diets help people in curbing appetites and preventing excessive eating of fats and carbohydrates.
The results represent the first scientifically supported  evidence that dietary protein plays an important role inappetite and total food consumption in humans, and are an important step in addressing the global obesity epidemic.
"Humans have a particularly strong appetite for protein,  and when the proportion of protein in the diet is low this appetite can drive excess energy intake.
"Our findings have considerable implications for body weight management in the current nutritional environment, where foods rich in fat and carbohydrates are cheap, palatable, and available to an extent unprecedented in our history," lead author Dr Alison Gosby said.
Protein is the driving force for appetite in many animals, according to the researchers. Although it has previously been suggested that protein content plays an important role in determining overall energy intake in humans, and is therefore linked to obesity, until now experimental verification has been lacking.
