Same genes linked to rapid infant growth, later weight gains

Infants who quickly add weight and length may be showing a genetic propensity for obesity as toddlers, a new study suggests.

In adults, certain genes have been linked to increased body fat, but the same genes in infants promote proportionate gains in fat and lean muscle, the researchers said. Continue reading

The childhood obesity window is closing: Genetic influence of height and weight grows as we get older

A new study on twins shows the importance of early intervention as America’s childhood obesity rate continues to rise after doubling during the past 30 years, with more than one-third of children overweight and obese.

By comparing data collected on more than 2,500 pairs of twins with genomic analysis, researchers from King’s College London and the University of California, Los Angeles (UCLA), got a pretty good look at the interplay between nature and nurture. They found the influence of genetics on individual differences in body mass index (BMI) rose from 43 percent at age 4 to 82 percent by age 10, suggesting parents and clinicians might intervene with improved diet and lifestyle choices at earlier ages — when the time is ripe.

Study: Fried food can cause some more weight gain, depending on genes

A diet full of fried foods isn’t good for anyone, but it may result in more weight gain for people at a high genetic risk of obesity, a new study suggests.

The study, published in the journal BMJ, is the latest evidence that life isn’t fair when it comes to navigating a world of french fries, soda, and comfy sofas — because some people are genetically predisposed to become fatter than others indulging in the same bad habits.

It’s a “groundbreaking concept” that could lead to more individualized prescriptions for weight control, says lead author Lu Qi, an assistant professor of nutrition at the Harvard School of Public Health. Continue reading

Obesity risk for kids who don’t taste ‘bitter’

Oct. 30, 2012, Futurity

Children who are less sensitive to bitter tastes are more likely to be obese — but only if they live where healthy food is hard to come by.

Neither genes nor the environment alone can predict obesity in children, but when considered together a strong relationship emerges, a new study shows. Continue reading
