Leptin targeted in research on obesity, pregnancy.
2002 DEC 12 - (NewsRx.com & NewsRx.net) -- Intent on helping Americans fight obesity, Agricultural Research Service scientists are probing the role that leptin plays in regulating appetite and weight gain.
Janet C. King and Ratna Mukherjea at the ARS Western Human Nutrition Research Center, Davis, California, are using results from their preliminary study of leptin levels in breastfeeding moms to design an expanded investigation with pregnant and lactating women.
Their earlier study showed that mothers who ate more carbohydrates in relation to fat during the months they were breastfeeding had higher levels of leptin in their blood. That's in contrast to lactating moms who ate more fats than carbs - the exact opposite of what's recommended in U.S. Department of Agriculture's dietary guidelines.
Higher leptin levels may help trim pounds gained during pregnancy. Leptin, made by the body's fat cells, is thought to help contribute to satiety, a feeling of fullness.
King and Mukherjea's findings are based on their multivariate analysis of food records and blood leptin levels ...
