“Protein Hunger” leads to overeating and obesity, scientists find a recent study suggests that the intake of a lot of processed food could deny a person of protein and could possibly lead to increased weight.
The researchers from Sydney University in Australia studied data on the eating behaviors of 9,341 locals. The data was collected between 2011 and 2012. The research was part of a national nutrition survey and was funded partly by a red meat marketing and research organization.
They discovered that people who consume more processed meals like chips, pizza, and another fast food end up consuming an excess of calories during the day. They also found that people who had a protein-heavy first meal of the day went on to eat a lower amount over the day. This could mean that a higher protein intake in the first meal of the day could possibly reduce appetite.
The researchers claimed that our bodies could possibly try to stimulate appetite resulting from a lack of protein. This hunger could lead to people eating processed foods excessively, instead of eating vegetables and other high-protein foods.
The research suggests that the amount of protein we eat affects the total intake of calories and whether or not we gain weight. The recommended intake of protein is measured in grams per day per pound of body weight and it is between 0.36 and 0.9 grams.
According to the researchers, our bodies have a target range of protein, so we will have to eat a lot more of it if it is a considerably small part of our usual diet, to balance it out.
Someone who weighs 150 pounds would require between 54 and 135 grams of protein daily. Each gram of protein is about four calories, which means 216 to 540 calories per day eating fish, beans, meat, soy, or chicken, which are high in protein.
If a regular diet of a person consists of 15% protein, they would need about 3,600 calories to reach the required amount of protein, and this could lead to increased weight. If that number increases to a 25% protein diet, they would only need a mere 2,160 calories per day from protein, which is in the recommended range if the aim is to maintain weight.
Obesity expert Giles Yeo said, “The hypothesis is that we need a certain amount of protein to function, and we will keep eating till we get to [the right number]. The data supporting it is quite solid. Most of the work was first worked out in flies and mice, but increasing evidence from human studies indicate it occurs, at least under certain conditions, in humans as well.”
Yeo further said that giving up processed food can be a challenge as it is convenient, flavorsome, and inexpensive. However, if we eat processed foods that are high in fiber and protein, they could prove to be a viable option in terms of calorie intake. Even so, having a lot of processed food can overshadow other mineral and vitamin-rich foods in your diet like whole grains, fruits, legumes, and vegetables.
In conclusion, Yeo highlights the importance of considering food as a whole and not only certain nutrients. He said that we don’t eat calories, we eat food.
