What Causes Obesity?

What causes obesity? Is it genetic? Is it lifestyle. And what about choices? You’ve probably heard that weight gain occurs when someone ingest more calories than they burn, but that’s certainly not the whole story.

Genetic factors contribute to the risk of obesity. But, many people who carry obesity genes do not become overweight and healthy lifestyles can counteract these genetic effects. It’s hard for some individuals who have addiction to sugar. Dopamine levels are involved and it’s just hard because of the way our society is wired. But let’s look at recent upward trends of obesity. Our genes really haven’t changed enough to explain that. So what has changed? Our food, which is a subject for another day, but also our activity level and our social eating patterns. Since the 1970s, the average caloric intake has increased by 500 kilocalories per day. Tracking rod, along with the increase in obesity. The standard American diet contains more fat, more sugar, more protein, more grains, and less fruits and vegetables. We’ve replaced nutrient packed foods with fast convenient food. And sweetened drinks. 

There’s a big study called the nurses health study. And for every two hours women in this study watched TV, the risk of obesity was increased by 25%. Now do the math. If you watch four hours of TV a day, your chances of being obese are increased by 50%.  

You will never reach a place where you can slack up and eat whatever you want and not gain weight. It’s not going to happen. So here are some practical tips. Replace your couch time with something you enjoy that’s active. Get up and march or dance or do squats. And eat more fiber. It fills you up, keeps your gut healthy and suppresses your appetite.  Eliminate ultra processed foods from your diet as much as possible. They’re loaded with fat and sugar to bring you back for more. Lastly, eat at home. Portions at restaurants are out of control and healthy choices are harder to make.
