How Many Years Does Obesity Cut From Lifespan?

MedPageToday has the details. A quote:

In a computer modeling study, very obese men lost just over 8 years of life compared with normal-weight men, and very obese women lost as many as 6 years, Steven Grover, PhD, of McGill University, and colleagues reported online in the Lancet Diabetes and Endocrinology.

They also found that very obese men and women (defined as a body mass index [BMI] of 35 and higher) lost about 19 years of healthy life, defined as living free of chronic disease such as diabetes and cardiovascular disease.

Note that “very obese” in this context has a specific definition: body mass index 35 or higher. Calculate yours.

The number of life years lost to obesity and disease were highest for those who were very obese in young adulthood and presumably stayed obese for years. In other words, becoming very obese at age 60 is not as dangerous as at 25.

I first got interested in weight loss in the 1990s when I had an office-based primary care medical practice. It was obvious that many of the medical problems I was treating were related to years of obesity. Believe me, you’re much better off preventing those problems via diet and exercise.

In the 1990’s, both Dr. Dean Ornish’s vegetarian diet and Dr. Robert Atkins low-carb diet were very popular, and you couldn’t find any two diets that were more polar opposites. And do you remember Susan Powter and her “Stop the Insanity” diet? My desire to lead my patients onto the right path resulted in the first edition of my Advanced Mediterranean Diet.
