Max Macaluso: What are some of the causes of obesity, besides poor diet?

Dr. Domenica Rubino: There’s obviously poor diet, manifested in a lot of different ways in terms of how we eat, and there’s different places that don’t have healthy food, or people who don’t have access to healthy food.

Sedentary — we’re all very, very sedentary. Unfortunately, we mostly drive to work, take the elevator, and sit at our computer, and go home and sit at our computer to relax. Exercise and just generalized movement and activity is a problem and contributes a lot to weight and the development of these diseases.

There are other things, though. Poor sleep. A lot of us — because now we can be up all night, 24/7, on the computer — we don’t get enough rest, and the risk increases for less than five hours of sleep. People have increased risk for weight gain and development of diabetes, and if they have sleep apnea, that’s an issue too.
