Why Can Some People Eat Fast Food Without Gaining Weight?

I always thought that some people were just blessed with hyper-active metabolisms, but new research is here to prove otherwise. This research shows that a diet of a lot of fat and salt could actually prevent weight gain. This isn't talking about keeping your arteries unclogged or skin looking nice...just your weight. The results come from an experiment where scientists put groups of mice on different diets, some 'healthy' and some on high-fat foods and high levels of salt. The group who gained the same amount of weight as mice eating normal food were the ones who ate the very salty and high-fat diet. So what does this mean? "It's totally different for each person," says Keri Gans, author of The Small Change Diet. "We always associate poor health with high weight, but you can definitely be a thin person and still have a lot of health complications that have nothing to do with your weight." I know I've said it plenty of times, how "lucky" people are because they can eat whatever they want, but this study also pokes holes in the logic that every skinny person is healthy, and every overweight person is fat.
