Undeniable snacking habits identical with obesity. More recently, researchers found that snacking habit is caused by too little protein in the diet. Then it ate a protein-rich foods such as meat, fish, eggs and nuts more will stop the habit of snacking.Researchers from Cambridge University and the University of Sydney recruited 22 volunteers with healthy weight and aged between 18 and 51 years later asking them to stay and eat in a facility that has been provided.
All volunteers were given food that looks the same, but actually have different levels of protein. Food provided for breakfast is a tasty muffin, grilled tuna with salad for lunch and pastel content of beef or spaghetti bolognaise with vegetables with dessert for dinner.
The amount of fat is set to remain constant at levels of 30 percent of total calories in food, but the carbohydrate content adjusted at levels 45, 50 or 60 percent of food consumed.
All the volunteers doing the same amount of physical exercise, ie walking for an hour while supervised and perform the same activities so that they do not eat out of boredom or stress.
Each volunteer was asked to assess the hunger that is felt at the time of one hour after eating. The result, the group that ate 15 percent protein to feel full two hours longer than the group that ate 10 percent protein.
People who consume 10 percent protein on average eat 1036 extra calories per day or 260 calories more than those who ate 15 percent protein. Not just eating more, 70 percent of those extra calories come from snacks consumed between meals.
The average adult in the UK eat about 12 percent protein from daily food intake. This amount has been considered by many to be due to decreased intake of protein by substitution of carbohydrates from processed foods.
"The results of this study indicate that humans have a very strong appetite to the protein. When low levels of protein in the diet, this powerful appetite can lead to excessive energy intake," said Alison Grosby, researchers from the University of Sydney.
To lose weight, nutritionists recommend a diet with a composition settings: a quarter of the food is protein, a quarter and half again is karbohiodrat is a vegetable.
"Eating large amounts of carbohydrates and fats such as those contained in soft drinks is a major risk factor for obesity and thus diluting the protein content will increase your appetite. We do not recommend to eat large amounts of protein or eliminate your intake of carbohydrates at all," said Dr.. Susan Jebb, co-author of the study and Chief Human Nutrition Research Unit at Cambridge.
"Protein intake by 15 percent of total daily diet must be sufficient to prevent overeating and helps people lose weight," added Dr. Jebb as reported by dailymail, Sunday (16/10/2011).
