Weight Loss Runs in the Family

It turns out that people who make an effort to shed a few pounds aren’t just in it for themselves; they may be helping their significant others trim down, too. Research published in the journal Obesity recounted a University of Connecticut study that monitored the weight loss progress of 130 people for 6 months—half of them on a structured Weight Watchers® program and the other half on a self-guided program combining education, healthy eating and exercise. The study discovered that about one-third of the volunteers’ cohabiting partners lost 3% or more of their initial body weight, even though they weren’t enrolled in the experiment.

The investigation also found that weight loss rates went hand in hand for couples: If one partner lost weight at a steady pace, the other one did, too. Likewise, if one partner struggled to lose weight, the other also had trouble scaling down.

Think of it as a ripple effect—when one half of a couple becomes dedicated to a healthier lifestyle, there is a good chance the other half will emulate the new eating and exercise habits. So, counseling a client on the importance of eating vegetables may very well put more kale on the partner’s plate, as well
