A breakfast that is rich in protein can put the brakes on hunger for the entire morning, according to research presented on November 14, 2013 at the annual meeting of the US Obesity Society in Atlanta. The study evaluated the effects of products with different nutritional compositions on the appetite when eaten as the first meal.
A questionnaire was given to a sample of women between the ages of 18 and 55, who had to declare sensations associated with hunger (need or desire to eat, feeling full) felt before breakfast, and at 30 minute intervals until lunchtime.
It emerged that with the same energy value (300 calories), as well as fat and fiber, those who ate a protein rich breakfast made it to the next meal without getting hungry again. In addition, they at less once they sat down for lunch than the group that skipped breakfast (drinking only water), or ate carbohydrates.
The balance the validity of starting the day with proteins, when traditionally cereals are consumed, is also confirmed by the Zone diet.
