Childhood overweight at age 7 raises diabetes risk if it persists into puberty.
A study of about 63,000 Danish boys measured their BMI at ages 7 and 13. By the time they reached age 30, 11% had developed type 2 diabetes. When overweight boys lost weight between ages 7 and 13 and maintained healthy weight into early adulthood, their risk was very similar to those who were never overweight.
PositiveTip: It is never too early to achieve and maintain a healthy body weight!
The "obesity paradox" may not be a real benefit.
Taking a life-course perspective, researchers have found obesity results in a shorter lifespan and an increased risk of cardiovascular (CVD) morbidity and mortality compared with those with a normal BMI (weight). Overweight men and women of all ages developed CVD at a younger age and spent more years living with it, despite not living as long.
PositiveTip: Maintaining a healthy BMI significantly improves quality of life, functional capacity, and decreases disability.
The healthiest people are those who have normal weight all the time!
A 2013 meta-analysis suggested that overweight individuals had lower all-cause mortality than those at normal BMI. Now data from three large cohort studies with more than 225,000 men and women has demonstrated there is no protective effect of being overweight. These researchers used the maximum weight achieved over the past 16 years in addition to current weight, demonstrating that trends in weight are very important.
The absence of excess body fat lowers the risk of most cancers,
Scientists have found 11 types of cancer show a strong association with excess body fat, according to a systematic review of the literature. The strongest evidence was seen for gastric, colon, rectum, bile duct system, pancreas, breast, endometrial, ovary, kidney, esophageal adenocarcinoma, and multiple myeloma.
PositiveTip: Avoid consuming excess calories and engage in physical activity daily to maintain ideal weight and reduce your risk of these common cancers.
There are no poor candidates for lifestyle change!
Many people who are overweight or obese often blame it on their genes. In a meta-analysis of nearly 10,000 subjects, researchers from England found even those with genetic risk factors for obesity respond as well as anyone else to diet and exercise. This data strongly suggests that obesity-linked genes do not affect the ability to lose weight.
PositiveTip: Don't blame your genes. While your genes may increase your risk of being fat, your choices of healthful lifestyle change make is possible to lose weight!
Twenty percent of cancers are related to excess body weight.
The World Health Organization's International Agency for Research on Cancer (IARC) has found growing evidence that losing weight may prevent obesity-related cancers. Those include postmenopausal breast, colorectal and esophageal cancers. The American Institute of Cancer Research estimates that if every American were at a healthy weight, 130,000 or more cases of cancer could be prevented.
PositiveTip: Intentional weight loss, when needed, can help lower cancer risk.
What can you do to help families with children prevent obesity?
Looking for a really sobering number to share with your friends? Here it is. One in every five children 5-17 years old is overweight or obese--in the 34 countries monitored by the Organization for Economic Co-operation and Development. Believe it or not, the U.S. is not the leader. Take a look yourself at the countries that lead the world in childhood obesity.
PositiveTip: Avoid highly processed, calorie dense foods and exercise as much as possible. It is good for your and your children.
Greater body fatness is probably a cause of advanced prostate cancer.
New evidence suggests there is strong evidence that being overweight or obese elevates the risk of advanced prostate cancer. This finding is from the World Cancer Research Fund's Continuous Update Project that analyzes global research on how diet, exercise, physical activity and weight influence cancer risk.
PositiveTip: Avoid being overweight or obese to lower your risk of deadly prostate cancer and many other serious diseases.
The biggest gains in obesity worldwide occured between 1992 and 2002.
From 1980 through 2013 the prevalence of overweight and obesity rose by 28% for adults. For children it is even more frightening--a rise of 47%. This scary picture of the global obesity pandemic is found in research done for The Global Burden of Disease Study 2013. There are now 2.1 billion people who are overweight or obese on this globe.
PositiveTip: Use your personal example and action to provide leadership in your community for effective intervention against this trend.
Morbid obesity increased risk for poor birth outcomes 2-3 fold.
A large global meta-analysis found nearly 25% increase in fetal death and stillbirths per five-unit increase in maternal BMI. Being overweight or obese before becoming pregnant increased the risk of poor outcomes compared to normal-weight women. The greatest risk was for the heaviest women, and this dose-response relationship suggests underlying biological mechanisms. The optimal pre-pregnancy BMI and and any threshold effects are yet to be determined.
