We all know one or two people who can eat virtually anything they want and yet they struggle to put on weight. Chicken wings, pizza, chips, ice cream - they eat it all but can't gain a pound. Meanwhile, if we did the same, it would be a completely different story. It's just not fair! Now, thanks to new research, we may have a better idea as to why this happens (although it may not make us feel any better!).
In a new Australian study, 40 individuals gorged on high-fat snacks every day for a month and their pattern of weight gain was observed. All participants ultimately gained weight, as they increased their daily caloric intake by about 1250 calories. What surprised the researchers, however, was that individuals with a family history of type 2 diabetes tended to gain even more weight than the rest of the bunch - nearly 3 pounds extra on average.
As with previous findings from other studies, the researchers believe that there is a genetic component to weight gain, and not everyone gains at the same rate. Certainly there are metabolic differences and varying predispositions to diseases and illness. Hopefully as more research is done on the genes and energy balance, we will better be able to tailor our eating patterns to help maintain a healthy weight.
