On Tuesday, in a recent study published in January 4 issue of the Journal of the American Medical Association included 25 people in Louisiana who agreed to live as in-patients in a weight-gain experiment for a 56-day period concluded that people eating too much high-calorie diet and low-protein diet are tend to gain more body fat than people who overeat high amounts of protein.
These people were overfed by about 1,000 calories per day over the course of about two months. It was seen that five percent protein were fed to some group of people , while the other ate 15 percent of protein to have a check on the normal level and others were given 25 percent protein, or a high amount. This allowed the researchers to uncover how different levels of protein might affect overall weight gain, body fat and energy expenditure.
Thus, it was found by the researchers that people on low-protein diet gained less weight overall than people on the mid-level and high-protein diets. But it was also revealed that more of their extra energy was stored as fat.
Later it was found in the study that low-protein eaters gained about half as much as the others and putting on an average of 3.16 kilograms (seven pounds) as compared to 6.05 kg in the normal protein group and 6.51 kg in the high-protein group.
The extra weight gain was in the form of lean body mass, which people on the mid- and high-level protein diets gained while those on the low-protein regime lost. Ninety percent of the extra energy consumed by people on the low-protein diet was stored as fat, compared to about 50 percent in the other two groups.
Thus while referring to the media; lead of research, George Bray of the Pennington Biomedical Research Center in Baton Rouge, Louisiana said that the key finding of this study is that calories are more important than protein while consuming excess amounts of energy with respect to increases in body fat.
