A new study suggests that the best way to help a family member or a loved one to shed those extra pounds is to stop criticizing them about their weight.

Researchers at the Renison University College at the University of Waterloo involved university-age women for the study. The participants were surveyed about their weight and height and how they feel about it. Five months later, the researchers asked them if they had discussed their weight issues with family or loved ones; they were also asked to share if they were given positive or negative responses. After three months, the researchers assessed their height and weight again.

"When we feel bad about our bodies, we often turn to loved ones - families, friends and romantic partners - for support and advice. How they respond can have a bigger effect than we might think," Professor Christine Logel, who teaches social development studies at the Renison University College at the University of Waterloo, said in a press release.

The analysis showed that those who were given positive acceptance messages about their weight were able to lose more weight, an average of a pound. Those who were given negative feedback gained an average of 4.5 pounds.

"The healthiest thing is for them to maintain the weight they have and not be so hard on themselves," said Professor Logel. "But many of the women were still very concerned about how much they weigh, and most talked to their loved ones about it."

The findings of the study implied that women feel better and more motivated to improve their weight and health when they are accepted by their family members and loved ones. Acceptance also lowers stress levels, one of the known causes of weight gain.

This study was published in the December issue of the journal Personal Relationships.
