Obesity alone does not increase risk of death

Geez guys, make up your minds /eyeroll/... here we go again (and again, and again and again):

I really don't blame the general public for being so utterly confused by the contradictory claims that they give up completely on science. Each week brings a reversal, then a reversal of the reversal and then back again, endlessly.

 

"Kuk's study showed that unlike dyslipidemia, hypertension or diabetes alone, which are related with a high mortality risk, this isn't the case for obesity alone.

The study followed 54,089 men and women from five cohort studies who were categorized as having obesity alone or clustered with a metabolic factor, or elevated glucose, blood pressure or lipids alone or clustered with obesity or another metabolic factor. Researchers looked at how many people within each group died as compared to those within the normal weight population with no metabolic risk factors.

Current weight management guidelines suggest that anyone with a BMI over 30 kg/m2 should lose weight. This implies that if you have obesity, even without any other risk factors, it makes you unhealthy. Researchers found that 1 out of 20 individuals with obesity had no other metabolic abnormalities.

"We're showing that individuals with metabolically healthy obesity are actually not at an elevated mortality rate. We found that a person of normal weight with no other metabolic risk factors is just as likely to die as the person with obesity and no other risk factors," says Kuk. "This means that hundreds of thousands of people in North America alone with metabolically healthy obesity will be told to lose weight when it's questionable how much benefit they'll actually receive."

This sounds reasonable to me.  5% of the obese are healthy without increased mortality - beyond the average non-obese person without metabolic risk factors.  ie, for 95% of the obese they are at increased risk of dying early.   And maybe the 5% of "healthy obese"  would have better than average health and mortality if they weren't obese...

Higher mortality is hardly the only harm caused by obesity.

 

Complications of obesity

Conclusion

Global obesity rates have increased exponentially in recent decades. This represents an enormous and growing health and financial burden. People are becoming obese younger, morbid obesity is increasing and the full health implications of this are only beginning to be seen.

 

Research shows that obesity is associated with increased mortality and numerous complications including diabetes, heart disease, dementia and cancer. Even low levels of overweight are associated with increased risk and weight loss remains the best way to tackle the complications. Without more urgent action, the obesity crisis already overwhelming our health services will also cripple our economy.

 

 

Obesity—kills 1 in 14 people currently—do you really care?

https://doi.org/10.1093/qjmed/hcy134

Obesity and its complications currently kills more people than road traffic accidents, terrorist attacks and Alzheimer’s disease combined. In England, the numbers of overweight/obese adults increased from 36 to 62% between 1980 and 2013. So that death rate will exponentially climb. Do we really care?

 

We really should. It is therefore appropriate that we publish a seminal review on the complications of obesity by Dr Kinlen and colleagues. This expanding list now includes enhanced risk for cancer, fractures, hypertension, diabetes, heart disease, stroke, dementia, asthma and obstructive sleep apnoea. In the context of cancer, it has been estimated that obesity accounts for up to 30%...
