Dear Liz: In one of your recent answers, you said “avoiding obesity” was part of choosing healthier lifestyles. The problem with that statement is that a large percentage of people cannot avoid obesity, because obesity is “wired” into their genes or otherwise into their personal biological makeup. People range all over the spectrum. I personally knew a guy who would normally eat four Double Double burgers plus fries when he ate at In-N-Out Burger, and he didn’t exercise, but he was trim as a telephone pole. But guys in my family have large lumps of extra fat on their bodies, even if we don’t eat that much.

Your casual mention unfortunately reinforced the false notion that people who have obese bodies always are that way because they eat poorly or too much, while people with trim bodies are always that way because they eat wisely and exercise. That false notion just makes life harder for those of us who have obesity regardless of how we eat. I’m sure you didn’t intend to make my life more difficult at all, but that’s the effect that such casual allusions have. It would be best to stick with unassailable phrases such as “eating wisely.”

Answer: Some people definitely are blessed with faster metabolisms, and research indicates that others have a genetic predisposition to packing on weight. But obesity is largely preventable, according to the World Health Organization and other medical authorities.

The WHO recommends that individuals limit the fats and sugars they eat, increase consumption of fruit and vegetables, as well as legumes, whole grains and nuts; and engage in regular physical activity (60 minutes a day for children and 150 minutes spread through the week for adults). Programs such as Weight Watchers or 12-step groups such as Overeaters Anonymous can help provide support. You may never be skinny, but you can definitely take steps to improve your health.
