First reaction: Yes! No more guilt! It's not my fault I'm putting on weight. It's the tiny little germs in my gut. They're the ones who don't have any self-control.
But if genes or viral infection or gut microflora are involved, then for some people 3,500 calories might not equal a pound of fat, and 150 fewer calories a day might not mean they’ll lose 10 pounds in a year. As scientists continue to investigate how obese people are different, we can only hope that a side benefit will be a more largehearted understanding of what it means to be fat and how hard it is to try to become, and to remain, less fat.You mean that because of some unicellular little git somewhere deep inside me, I now have to diet harder than thin people to lose weight? Aaarggh!!
