Obesity May Begin Before Birth, Researchers Suggest
Posted Dec 18 2008 8:14pm
Some researchers are proposing a provocative new medical theory about obesity, which suggests that obesity begins much earlier than previously believed -- possibly long before they're born, Newsday reports.
In particular, as doctors have known for years, babies born to mothers with diabetes have an increased risk of being larger and fatter at birth and that risk doesn't lessen with age. Even though they often lose weight as toddlers, they're likely to gain weight during childhood and adolescence.
Now new research is looking at other perinatal factors that may increase the chances of obesity.
But these new ideas run counter to conventional thinking, which almost exclusively attributes excess weight to our dietary and lifestyle choices.
