Many Japanese moms-to-be don't gain enough weight, and experts say that could cause lasting problems

(CNN)Naomi Hayami-Chisuwa, who gave birth in June at age 35, found it hard to control her weight during pregnancy, particularly as she came closer to the due date.

Despite being a normal weight, the dietitian and lecturer at Osaka City University had been advised by the hospital where she received health care to gain only 10 kilograms until delivery, slightly less than the official government guideline of 7 to 12 kilograms (about 15 to 26 pounds), she said.
Tipping the scales proved stressful to this working mother-to-be, who could not attend daytime pregnancy education classes and so was advised to "take nutrition counseling twice when my weight increased over the recommended weight gain per week."
    For the sessions, she created a record of her diet and this was examined by nurses "to find eating behaviors which may be related to weight gain," she said. In her case, no specific recommendations were given because her diet and behaviors were healthy.
