Behavioural therapy for obesity may help family too

obese people lose weight with behavioural therapy, their family members may get a bit trimmer as well, a new study suggests.

Cognitive-behavioural therapy (CBT) is one option for managing obesity, though it’s not widely available. It focuses on changing people’s thoughts and attitudes on eating and other lifestyle habits, and giving them practical ways to make improvements — like tracking their daily calories and keeping an “eating diary.”

In the new study, Italian researchers wanted to know whether the things obese patients learn in CBT might have a “ripple effect” in their families.

They surveyed family members of 149 obese patients going through the CBT programme at the University of Bologna — which consisted of 12 to 15 weekly group meetings.

Six months after their relatives started the programme, the study found, family members — mainly spouses and adult children — showed some changes for the better as well.

On average, they’d cut more than 200 calories from their daily intake at the study’s start. They were also eating a bit less fat and refined carbohydrates, and a more fruit.

It all translated into a weight loss of just over two pounds, on average. But the effects were bigger for the 35 relatives who were actually obese themselves.

They lost an average of six pounds, and seven of them lost enough to become officially “overweight” instead of obese.

“CBT in a family member might have a ripple effect (for) other family members,” senior researcher Dr Giulio Marchesini said in an e-mail.

One reason could be that family members decided to make positive changes to help the person who was in CBT — like ridding the kitchen of sugary, fatty

bit temptations.

Even more likely, Marchesini said, is that the person in behavioural therapy instituted some healthy changes at home. A majority of the CBT patients — 101 of the 149 — were women, and were likely “in charge” of meal planning, Marchesini pointed out.

“I do not know how much this possibility might translate into different cultures,” he noted, “but this is definitely the case among Italian families.” — Reuters Health
