Story highlights President Donald Trump is a pound shy of being considered obese, say the results of his latest physical

The majority of American adults are overweight or obese and don't get enough exercise

(CNN) President Donald Trump's doctor, Dr. Ronny Jackson, characterized the president's health as "excellent," but like the majority of Americans, Trump is overweight and he doesn't get enough exercise.

The President weighs 239 pounds. That means he's gained 3 pounds over the last year, according to his last official records. At 6 feet, 3 inches tall, Trump had a body mass index, or BMI, that puts him in the "overweight" range, according to the National Institutes of Health's online BMI calculator. Being overweight is simply defined as a person whose weight is higher than what is considered a normal weight adjusted for height. The President is one pound shy of being considered obese, according to these calculations.

He is not alone. According to the National Health and Nutrition Examination Survey, more than one in three adults were considered to be overweight and more than one in three were considered obese. That means the percentage of adults age 20 and older who are overweight or obese is 70.7%, according to the Centers for Disease Control and Prevention.

BMI, however, is considered by some experts too limited a measure , since this calculation doesn't distinguish between fat and muscle. It's the fat, rather than the weight , that hurts your health. A better way to measure obesity is an X-ray, which can distinguish between fat and other innards. Or some hospitals use a bioelectrical impedance analysis, which runs an electrical current through body tissue to determine fat composition. Even measuring waist circumference is thought to be a better measure of fat than BMI. None of those tests was performed. A doctor could even eyeball it and if the patient's waist is bigger than the hips, the risk of premature death is considered much higher for that person than someone whose waist circumference is smaller .

Jackson said he will work with Trump to design an exercise routine and eating program that will help him get a better handle on his weight. The President said he would like to lose some, according to Jackson.
