Breastfeeding has many advantages for mothers and babies. But unlike popular belief, it does not seem to help the new mothers pour faster weight after pregnancy.
The discovery comes from the researchers Karen Wosje, PhD, and Heidi Kalkwarf, PhD, RD, from the Hospital Children Cincinnati Medical Center.
The pair studied data from a total of 326 new mothers to see if breastfeeding made any difference in weight loss or body fat.
Previous studies on the topic were contradictory leaving the effects of breastfeeding in weight and light body fat.
Body Beast For Fat Loss - Breastfeeding Doesn't Trim Body Fat Quickly
First, Wosje and Kalkwarf focused on new mothers during a six-month study that analyzed changes in the body after delivery.
with new mothers, body composition can change rapidly after delivery. In the first six months after giving birth, the 81 non-destructive mothers of the study have lost fat all the body, arms and legs faster than the 87 mothers who breastfeed.
In addition, lactating women gained fat in their arms.
A change in body composition was determined by the whole body image and determining fat and muscular mass.
However, both groups lost weight at similar rates and body weight decreases were not influenced by breastfeeding. All mothers lost some fat on their trunk (chest, stomach and pelvic region), but it was the rate of fat loss that differed.Mothers who breastfeed can also consume more calories. In mothers who breastfeed, hormonal prolactin stimulates appetite, as well as milk production prompts, which could explain the extra calories consumed by these women.
In addition, nonbereastfeed women reported a more intense physical activity than breastfed.
Next, the researchers examined data from women who had babies six to 12 months earlier.
Until then, any differences in the body composition between the lactating and non-lactating mothers disappeared.
"There was no influence of lactation ... in fat losses in women in the study of weaning," writing researchers.
"Body weight decreased rates and fat percentage fat have not been significantly influenced by lactation."
On average, all women in the study of weaning lost fat mass on all body sites. The body composition continues to change until at least a year after giving birth, say the researchers.
The researchers also wanted to see if the calcium made a difference in weight loss or body fat, since it was suggested that calcium promotes weight and Loss of fat.
No effect in this study.
1-grim calcium supplements per day (1 g / d) did not make a difference in weight or fat loss in any of the mothers.
"We observed no beneficial influence of calcium supplementation in changes in weight or fat mass," write the researchers at 1 issue of issuing the American newspaper of clinical nutrition.
The researchers did not know if any of the women was intentionally trying to lose weight during the study.
Researchers do not recommend weight loss and fat loss a priority in considering whether breastfeeding is best for mothers and their babies.
