Select San Antonio schools will use high-tech cameras to photograph cafeteria foods as part of a USDA pilot project to measure the nutritional value, calories and size of school meals. The cameras will record what students buy and take a second shot of their tray before they throw it away to determine exactly what is being consumed.

Pregnant women with a body mass index of 35 or higher who lost weight or gained less than the recommended 11 to 20 pounds had a lower risk of having a large baby or undergoing cesarean section than those in the recommended weight-gain range, according to a study of more than 46,000 obese pregnant women published in Obstetrics & Gynecology. The researcher said the study suggests that gaining less than the recommended weight or even losing pounds is "at least not harmful" for severely obese pregnant women, although the study did not determine a safe weight-loss range.
Cooking shows, including reality-TV programs such as "Hell's Kitchen," create more informed consumers and do not necessarily add to the nation's obesity problem, says dietitian Tanya Zuckerbrot, creator of the F-Factor Diet.
