When you are pregnant, you tend to eat a lot because you're always hungry and yes, you are eating for two. But gaining too much weight during pregnancy may up your unborn child's risk of obesity later in life. This is according to the findings published in the British Journal of Nutrition. Researchers found that baby rats born to mothers who consumed foods high in sugar, fat and salt ate 22 percent more calories per day and were likely to choose junk food over healthier options than those born to mothers who ate balanced meals. They believed that a mother's eating habit during pregnancy may program the appetite control center in her child's brain to overeat and make unhealthy food choices. So preggos, be careful with what you eat. Go for healthy ones if you do not want to have an obese child in the future.
