Why am I not losing weight?

Story highlights

Half of overweight and obese adults report that they are trying to lose weight

One common issue is that people often eat more calories than they realize

CNN  — 

Weight loss is still incredibly challenging for most people, as evidenced by the growing global obesity epidemic.

According to the latest Centers for Disease Control and Prevention statistics, more than two in three US adults are considered overweight (defined as a body-mass index over 25), and of those, 36.5% of US adults fall into the obese category (BMI greater than 30).

Many people also want to lose weight. According to a recent study in the Journal of the American Medical Association, approximately half of overweight and obese adults report that they are trying to lose weight. Which is why my patients often ask, “Why aren’t I losing weight?”

There is no simple, universal answer to this question, but after nearly two decades of working with patients trying to lose weight, and with the help of two leaders in the field of nutrition and obesity medicine, I’ve put together this list of some of the most common behavioral and medical reasons you might not be losing weight, even though you think you are doing everything right. I’ve also tried to include suggestions to get you on the right track to sustained weight loss.

You have calorie ‘amnesia’

This is one of the most common and easy-to-fix issues that I see in my practice: Put simply, people often eat more calories than they realize.
