Obesity: Unhealthy and unmanly – Harvard Health

It’s obvious that obese and obesity are huge issues in the United States. At present, two-thirds of all Americans require to lose weight, and the variety of obese children and grownups is growing at an alarming rate.

And it’s no secret that weight problems is bad for health. Excess body fat raises levels of LDL (“bad”) cholesterol and triglycerides while also decreasing HDL (“excellent”) cholesterol levels. Obesity impairs the body’s responsiveness to insulin, raising blood sugar and insulin levels. But obesity does more than produce bad numbers: it likewise leads to bad health, increasing the danger of cardiovascular disease, stroke, high blood pressure, diabetes, gallstones, cancer, osteoarthritis, obstructive sleep apnea, fatty liver, and anxiety. All in all, weight problems is a killer; in reality, weight problems and absence of exercise are accountable for about 1,000 American deaths each day, and if present patterns continue, they will soon surpass smoking cigarettes as the leading preventable causes of death in the U.S.

Weight problems impacts males and females about equally. However you might be amazed to learn that men bear a particular concern, because weight problems takes an unique toll on male hormonal agents, sexuality, and prostate health.

Am I obese?

An appearance in the mirror can offer you an idea, but to find out if your weight puts you at risk for genitourinary disorders, you require a more exact evaluation.

At present, the gold standard is the body mass index, or BMI. You can determine your BMI by multiplying your weight in pounds by 703 and then dividing by your height in inches squared or by dividing your weight in kgs by your height in meters squared. Or, if you resemble the majority of us, you can avoid the mathematics and use an online calculator.

The BMI offers a reasonable quote of general body fat. A BMI in between 25 and 30 puts you in the obese category, while a reading of 30 or more says you’re overweight. But the BMI doesn’t inform you how your fat is distributed. Scientists know that while no excess body fat is good, abdominal fat is the most harmful variety. So to find out if you are at risk, merely measure your waist at your navel; for men, threat starts to increase at waist areas above 37.5 inches, and troubles install over 40 inches.

Weight problems and testosterone

Testosterone is the major male hormone. As such, it is accountable for the deep voice, big muscles, and strong bones that characterize our gender, for advancement of the male reproductive organs, for sperm production and libido, and for the normal male pattern of beard development. After being transformed to dihydrotestosterone, the hormone likewise spurs growth of the prostate, which is a much less welcome indication of manhood for older gents.

Testosterone levels surge at puberty and peak in early their adult years, and then after a couple of years of stability, the hormone begins a sluggish drift downward in early middle age. Due to the fact that the drop in testosterone averages just 1% a year, most older males maintain typical levels. However anything that accelerates the decline can nudge some males into testosterone shortage.

Obesity decreases testosterone levels. For instance, a 2007 research study of 1,667 guys ages 40 and above discovered that each one-point boost in BMI was connected with a 2% decline in testosterone. In addition, a 2008 study of 1,862 men ages 30 and above found that waist circumference was an even stronger predictor of low testosterone levels than BMI. A four-inch boost in waist size increased a male’s chances of having a low testosterone level by 75%; for comparison, ten years of aging increased the chances by just 36%. All in all, waist circumference was the greatest single predictor of establishing signs of testosterone deficiency. And if you question these 2 American research studies, simply consider Australian research that found almost one in every seven obese guys could benefit from testosterone replacement, a rate more than four times greater than in nonobese guys.


Although men with erectile dysfunction (ED) often blame testosterone, hormonal disorders account for just 3% of ED. However even with regular testosterone levels, men who are overweight have actually an increased danger of ED. For instance, a Harvard study found that a male with a 42-inch waist is twice as likely to establish the issue as a gent with a 32-inch waist. Brazilian research likewise linked abdominal obesity to ED, however only in men older than 60. And a California study reported that having a BMI of 28 (overweight however not obese) increased a male’s odds of developing ED by over 90%.

Developing a link is something; finding a method to enhance erectile function, another. However a Massachusetts research study found that weight loss can certainly enhance things for obese men with ED. Comparable outcomes were reported by Italian researchers who randomly designated 110 overweight men with ED to a diet and workout program or to simply continue their typical care. After two years, more than 30% of the guys in the diet plan and exercise group had actually fixed their ED without medication, compared to less than 6% in the group that received their normal level of healthcare. Men who lost the most weight took pleasure in the best benefit.

Reproductive function

Weight problems takes a toll on sexuality, and it may also hinder fertility. American research has linked weight problems to low sperm counts and reduced sperm motility; German scientists reported similar findings in males in between 20 and 30.

Kidney stones

ED can trigger excellent psychological pain for males and their partners. Kidney stones are much less individual but cause much more physical discomfort. Stones strike men twice as typically as women, and weight problems increases a man’s danger.

A Harvard study of 45,988 males ages 40 to 75 found that high BMIs and large waist areas are both linked to an increased danger of kidney stones. Guy who gain more than 35 pounds after age 21 are 39% most likely to establish stones than men who stay lean. Guy who weigh more than 220 pounds are 44% most likely to have stones than males who weigh less than 150 pounds. These American outcomes do not discuss the reason for the link, but research from Europe and Asia reveals that overweight individuals dispose excess quantities of calcium and other chemicals into their urine, where the chemicals form stones.

Benign prostatic hyperplasia

Benign prostatic hyperplasia (BPH) ends up being more common as males get older. It also becomes more typical as guys gain girth.

A Harvard research study of 25,892 males discovered that waist circumference was highly related to a man’s risk of establishing BPH signs. Guy with waists of 43 inches or larger were 2.4 times most likely to need surgery for BPH than guys with waists smaller sized than 35 inches. The Harvard research study did not link BMI as an independent danger element, but a Baltimore research study did. And scientists in Baltimore and China provide an explanation; they utilized ultrasounds and MRIs to determine the prostate gland and found that guys with bigger stubborn bellies have larger prostates.

PSA levels

The prostate gland is understood for scientific puzzles and paradoxes. Here’s another: prostate-specific antigen (PSA) levels increase as the prostate gland increases the size of, and although weight problems appears to grow the prostate, it also decreases the PSA level. According to the 2001– 2004 National Health and Nutrition Examination Survey of Caucasian guys ages 40 and older, each five-inch increase in waist area leads to a 6.6% decrease in blood PSA levels. But unlike many prostate puzzles, this one has an option. A study of 13,634 prostate cancer patients discovered that males with higher BMIs had lower PSA levels, not since their prostates produced less PSA, however due to the fact that weight problems increases blood volume, so PSA is more watered down in the blood.

Prostate cancer

Since obesity lowers PSA levels, it can make it harder for physicians to use PSA measurements to detect prostate cancer in obese guys. That’s a numbers video game caused by an artificial lowering of PSA. However obesity likewise has an unfavorable result on the biology of prostate cancer.

Research from worldwide shows that extra body fat increases a guy’s threat of establishing prostate cancer. An American Cancer Society study of 404,576 males demonstrated the link: being overweight increases a male’s risk by 8%, being overweight boosts threat by 20%, and being severely overweight boosts threat by 34%. And that’s not all. Obesity increases the odds that prostate cancer will spread beyond the gland, and it likewise makes regression after treatment more likely. In addition, weight problems boosts a guy’s opportunity of developing urinary incontinence after a radical prostatectomy operation.

Why is obesity such bad news for prostate cancer? Overweight males tend to put off healthcare and they have lower PSA levels, so delayed medical diagnosis belongs to the explanation. But obesity likewise modifies the metabolic process of sex hormones, which could affect the development of prostate cancer. Essential, possibly, weight problems increases the body’s production of growth aspects such as insulin and insulin-like growth factor 1 (IGF-1). Both increase the rate of cell reproduction, and high blood levels of IGF-1 have actually been connected to an increased threat of prostate cancer, colon cancer, and other malignancies.

Why weight?

In today’s America, being overweight is the norm– however it’s not normal. In reality, this typical problem is one of the important things that make diabetes, hypertension, stroke, cardiovascular disease, and arthritis so common. And if that’s okay enough, it also increases the risk of male maladies, varying from impotence to BPH and prostate cancer.

It’s hard to shed excess pounds, but it is possible. There is no fast fix, but there is a slow fix: change your diet to take in less calories and increase your exercise to burn off more calories. It’s the manly thing to do, and the time to begin is now.

When it comes to improving your health, don’t weight.
