Increasing body fat accumulation significantly raised men's odds of developing advanced and fatal prostate cancer.
More Evidence Links Body Fat with Prostate Cancer
Walker, Molly. "Quarantine Brings up More Issues for Patients with Obesity." MedPage Today, June 10, 2020.
Patients with obesity not only reported more anxiety and depression, but the majority reported less exercise, more stress eating, and increased stockpiling of food due to COVID-19 stay-at-home orders, researchers found.
"American Cancer Society Updates Diet & Physical Activity Guideline for Cancer Prevention." American Cancer Society, June 9, 2020.
The American Cancer Society has updated its guideline for diet and physical activity for cancer prevention, with adjustments to reflect the most current evidence. The updated recommendations increase recommended levels of physical activity and have an increased emphasis on reducing the consumption of processed and red meat, sugar-sweetened beverages, processed foods, and alcohol. They also include evidenced-based strategies to reduce barriers to healthy eating and active living and to reduce alcohol consumption. The guideline is published in CA: A Cancer Journal for Clinicians, the ACS’s flagship medical journal.
Nackerdien, Zeena. "Losing Weight after age 50 may lower breast cancer risk." MedPage Today, January 15, 2020.
In the Journal of the National Cancer Institute, Lauren R. Teras, PhD, of the American Cancer Society in Atlanta, and colleagues found that women age 50 years or older who lost weight and kept it off had a lower risk of breast cancer compared with those whose weight stayed the same.
Nackerdien, Zeena. "Obesity in America: Who is Most Affected?." MedPage Today, January 2, 2020.
Nearly half of U.S. adults will be obese by 2030 if current trends continue, with almost one-quarter projected to be severely obese, according to an analysis considered highly predictive that corrected for self-reporting bias. Note that severe obesity is also likely to become the most common body mass index category among women, non-Hispanic black adults, and adults with low income.
Jeff Minerd. "Obesity-Associated Cancers on the Rise in Younger Patients." MedPage Today, 8/15/19.
Obesity-associated cancers are affecting people at earlier ages in the U.S., a population-based study found.
The analysis of more than 2.6 million incident cases from 2000 to 2016 found that the percentage of new cases of obesity-associated cancer occurring in individuals 65 and older decreased over this interval, whereas it increased in those ages 50-64, said Siran Koroukian, PhD, of Case Western Reserve University School of Medicine in Cleveland, and colleagues.
Bankhead, Charles. "More Evidence Links Body Fat with Prostate Cancer." MedPage Today, June 12, 2019.
Increasing body fat accumulation significantly raised men's odds of developing advanced and fatal prostate cancer, data from a large prospective study of men in Iceland showed.
Higher concentrations of visceral and thigh fat increased the odds of aggressive or fatal prostate cancer by 30%-40% as compared with leaner men. The prostate cancer risk associated with increased visceral fat accumulation carried over to men who had a lower BMI, reported Barbra A. Dickerman, PhD, of the Harvard T. H. Chan School of Public Health in Boston, and colleagues.
Collins, Frances. "Ultra-Processed Diet Leads to Extra Calories, Weight Gain." NIH Director's Blog, May 21, 2019.
If you’ve ever tried to lose a few pounds or just stay at a healthy weight, you’ve likely encountered a dizzying array of diets, each with passionate proponents: low carb, low fat, keto, paleo, vegan, Mediterranean, and so on. Yet most nutrition experts agree on one thing: it’s best to steer clear of ultra-processed foods. Now, there’s some solid scientific evidence to back up that advice.
McGinley, Laurie. "The Disturbing Links Between Too Much Weight and Several Types of Cancer." The Washington Post, April 14, 2019.
"Higher consumption of sugary beverages linked with increased risk of mortality." Harvard T.H. Chan School of Public Health, March 18, 2019.
The more sugar-sweetened beverages(SSBs) people consumed, the greater their risk of premature death—particularly death from cardiovascular disease, and to a lesser extent from cancer, according to a large long-term study of U.S. men and women. The risk of early death linked with drinking SSBs was more pronounced among women.
Incollingo, Beth Fand. "Sweet Surrender: Will Cutting Out Sugar Help You Prevent Cancer?." CURE, February 20, 2019.
The latest findings about the dangers of eating sugar and carrying extra body fat may spell bad news when it comes to dietary freedom, but being aware of them gives people the power to lower their cancer risk.
Recent studies confirmed that two diet-related culprits can contribute to the development of cancer: eating sugar, which increases the body’s production of insulin, and having excess body fat, which leads to inflammation. Perhaps surprisingly, these processes happen not only in those who are obese or overweight but also in people who are considered a normal size based on their body mass index (BMI).

Does what we eat and drink affect our risk of developing cancer?
Joseph, Andrew. "Seven U.S. states now have adult obesity rates of 35 percent or higher." STAT, September 12, 2018.
In its report, the CDC called for a comprehensive strategy to reduce obesity prevalence, with steps including healthy eating, better sleep, stress management, and physical activity.
Harrison, Pam. "For Obesity-Related Cancers, Both BMI and Weight Gain Matter - Still, effects differ among different tumor types." MedPage Today, May 29. 2018.
A high body-mass index (BMI) as well as gaining large amounts of weight irrespective of starting BMI both contribute to obesity-related cancers, although not necessarily the same ones, a large epidemiological study from Norway suggested.
Shockney, Lillie D., RN, BS, MAS, ONN-CG. "Obesity Is Tied to Increased Risk for Cancer Among the Young." Academy of Oncology Nurse and Patient Navigators, April 9, 2018.
Evidence from more than 100 research publications has shown that obesity increases the risk for 13 different cancers in young adults. This meta-analysis describes how obesity has shifted specific types of cancers to younger age groups, and intensified cellular mechanisms that promote the disease.
Scott Gottlieb, MD. "Reducing the Burden of Chronic Disease." US Food & Drug Administration, March 29, 2018.
More than 630,000 Americans die every year from heart disease.
It’s followed closely by cancer as the second leading cause of death in America, with another 600,000 Americans dying annually from cancer.
While we’ve made progress in reducing deaths due to cancer and heart disease -- in part due to reductions in smoking -- some of that progress is now being offset by the increasing problem of obesity.
