Posted on: March 10, 2013   by  John Cannell, MD

Obesity among teenagers is epidemic. It is a leading preventable cause of death worldwide, with increasing prevalence in adults and children, and authorities view it as one of the most serious public health problems of the 21st century. For reasons no one actually knows, obesity was rare before the 20th century.

One problem in obesity is that insulin resistance increases and insulin levels rise, leading to diabetes.

    Another recent study of Insulin resistance used 50,000 IU of vitamin D weekly (> 7,000 IU daily) for 8 weeks with good results. http://www.vitamindwiki.com/tiki-index.php?page_id=3882

    Dear Dr. Cannell,

    Thank you for the excellent post…

    I have found that once my 25(OH)D level reached approximately 75 ng/ml, my weight dropped from around 135 to 105 lbs, effortlessly. I believe it was in part due to lower leptin, as my appetite did significantly decrease (especially my desire for carbs..and I used to desire carbs quite a bit).

    I also think that raising my 25(OH)D level corrected a sluggish thyroid.

    I did want to quote from your post: 🙂

    “Lastly, obese or not, I think all teenagers are at risk of vitamin D deficiency, as so many of them are in school all day and in front of the computer and TV on weekends.”

    This statement is obviously true…however, I ask you to also consider that those of us who live way above 32 deg N…like I do in Cheshire, CT…we really (truly) have solar death for about half the year.

    We could stand outside naked…or better yet..on top of our roof tops…at HIGH NOON in February (we’d be cold for sure), but we wouldn’t make any Vitamin D…

    Take care,
    Rita Celone Umile
