Consumption of high protein diet during the period of active growth is associated to the occurrence of adult obesity and diabetes type 2,  says a new study published by the journal Nutrition and Metabolism this month.

In this study, a group of Wistar rats were weaned and assigned onto a control diet, a high protein diet or a high fiber for a fourteen-week period.  After this weaning period, they were then shifted to a high fat/high sugar diet for another six-week period. After this, body composition and energy intake were then studied.  In addition to this, laboratory tests such as  oral glucose tolerance test and blood satiety hormone  were taken.

The results of this study showed that males rats who had the high fiber diet have a better weight control compared to their high protein rat counterparts.  Furthermore, the researchers also noted that the final body weight of rats with the high protein diet is significantly much higher than those who ate the high fiber diet.  In female rats, a well-modulated body weight reduction  was observed in those eating the high fiber diet compared to those who ate the high protein diet.  In addition to this, it was also observed that the lean muscle mass was much higher in the high fiber group than that of the high protein group.  High energy intake was much higher in those rats who had the high protein diet than those who had the high fiber diet. Moreover, it was mentioned in this study that those who had the high protein diet have a higher liver fat content that their counterparts who are the high fiber diet.

With these results, the researchers have concluded that a long-term high protein diet during the growing years can predispose an individual to obesity when introduced to high energy containing foods during adulthood.  However, a diet rich in fibers during the growth can provide some ample protection from the occurrence of obesity later during the adult life.
