Washington, March 1 (IANS) President Barack Obama's doctor has given him an excellent bill of health but has obliquely asked him to cut down on those cheese burgers he sneaks off to eat once in a while.

'The president is in excellent health and 'fit for duty,'' Dr. Jeff Kuhlman, a Navy captain and physician to the president wrote in his report after Obama's first check-up Sunday. 'All clinical data indicate that he will remain so for the duration of his presidency.'

The doctor did recommend Obama change his eating habits a bit. 'Recommend dietary modification to reduce LDL cholesterol below 130,' Kuhlman wrote.

The report - made publicly available as Americans want to know the state of health of their chief executive - lists Obama's LDL level at 138. LDL, or low-density lipoprotein, is what's known as 'bad' cholesterol, according to the American Heart Association.

'Cool' Obama had a resting heart rate of 56 and a blood pressure reading of 105-62. Kuhlman noted that the 48-year-old president should keep up his efforts to stop smoking. Obama's medications include nicotine replacement therapy.

The 6-foot-1-inch president weighed in at 179.9 pounds with his shoes and workout attire on.

His body mass index (BMI) is 23.7. According to the Centres for Disease Control and Prevention, that's in the upper end of the 'normal' weight range. 'Overweight' begins at 25.0.

The White House said Obama's doctor recommended his next physical take place in August of next year, when the president turns 50.
