Food habits and lack of exercise also play a big part in getting obese.
A study suggests that obesity is more linked to lack of exercise and considerable shift in diet to unhealthy pattern and not just genes.
The study says genes do play a role but the excess kilos don’t just depend on them. Food habits and exercise also do play a part in getting obese.
For people genetically predisposed to a wider girth, these unhealthy lifestyles compounded the problem, resulting in an even higher rate of weight gain, researchers reported in The BMJ, a peer-reviewed medical journal.
A BMI of 25 up to 30 means that one is overweight. Thirty and above corresponds to obesity, a major risk factor for heart attacks, stroke, diabetes and some cancers.
About four percent of adults in the mid-1970s had a BMI of 30 or higher. By 2016, that share had risen to 13 percent (11 for men and 15 for women), according to the World Health Organization.
Half of the people monitored were divided into five groups depending on their genetic susceptibility to obesity.
Comparing the two groups at the extremes, the researchers found, for example, that 35-year-old men with genetic variants known to favour weight gain were already heavier in the mid-1960s than men the same age without those fat-inducing genes.
Four decades later -- even as obesity rates increased across the board -- that gap nearly doubled.
A food additive which is commonly used as a whitening agent in products such as chewing gum and mayonnaise could lead to inflammatory bowel diseases and colorectal cancer, warns a study.
Children of poorly-educated mothers face higher risk of obesity than those whose mothers are well-educated, suggests a new study.
High school students who take music courses score significantly better in exams than their non-musical peers, says a study.
"Very disheartened at Manchester Airport today, I travel around the world with my insulin but never have I been made to feel embarrassed. I felt very humiliated as I was rudely questioned & ordered publicly to take my insulin out of its travel cold-case & dumped in to a plastic bag," Akram said in a tweet.
