Obesity Tied to Higher Cancer Rates in Younger People

Although I didn’t watch the Super Bowl, like many others I like to watch the commercials the day after. Besides the clever ads for Pringles and Doritos, surely not things your great grandmother would have recognized as “food”, I was struck by the commercial (apparently considered controversial because of its winking references to porn addiction) involving a middle-aged man addicted to frozen food meals. I particularly noticed the scene where the husband pushes away his wife’s apparently home-cooked plate of food in favor of the pre-prepared frozen dish. Living in a country where food is, ideally, supposed to be tasted and savored, the fact that these meals are sold under the brand name “Devour” really made me wince. Although I can appreciate the creative genius and sense of humor behind such advertising, America’s continuing addiction to processed foods, high in fat, sugar and salt, and the resulting obesity epidemic, is no laughing matter.
Dr. Becky (York, PA)
@Susan Agreed. Although some times a frozen meal is a necessity and there are healthy options. On DrBeckysHealthDoneRight.com you will find some. As an obesity medicine doctor I included this option for when people are in a hurry but still want to eat relatively healthy.

As a physician, I would tell my obese patients to lose weight and hope that they wouldn’t ask me how, before I retired. If they asked, I would send them to a nutritionist who probably didn’t know either but would give them a reduced calorie diet, leading to weight loss, slower metabolism and hunger. Nature’s way of keeping you “healthy” at your previous weight. Now I am 35 pounds lighter for 3-4 years. The low carb diet is the only one studied that does not have to place a caloric restriction on the subjects. You do have to stay low carb but a 100 gram carb limit, not impossible, will keep your weight down. Processed food particularly meats are not good for the bacteria in your gut. The processed agents are there to keep the food stable, but they are not kind to your friends in the gut. Lean red meats cause no cardiac risk unless they are processed.
Dr. Becky (York, PA)
@W. Scott Brooks Dr. Brooks, kudos to you. Your low carb diet is reasonable, especially if you are getting most of them in the form of whole grains and fresh fruit. There appears to be a lot of carb bashing these days and people are steering away of some healthy and necessary carbs. The CDC has red meats limited to 2 servings a week. They don't mention grain-fed but my review of the literature supports grain-fed. Thanks for sharing.

I spoke to a cab driver from Somalia the other day. He said “all of our health issues are due to not having enough to eat. All of your health issues are due to eating too much”

Just because you can find it in your grocery store doesn't mean it's not deadly. Eat real foods and for Pete's sake LEARN about nutrition! Parents who fail to do this are failing their children.
Jake (Chicago)
Good article, but what is the absolute increase in the cancer rates? Saying that cancer rates doubled gets the headline. But mentioning the absolute rate increase would give us readers proper understanding and perspective. For example: if the non-obese population has a 1 in 100 chance of getting a type of cancer, while an obese person has a 1 in 50 chance, that is a 100% relative increase. It's also an absolute increase of just 1%.

Too many of our frazzled, overworked, undereducated and generally unhappy fellow humans are substituting easy fast junk food for comfort and warmth. It's a terrible thing to watch happen.

I know two brothers who are in their early 70's. One has eaten a pretty healthy diet his entire life - both he and his wife love to cook and I can promise you that junk food never enters the door of his house. Both have had the occasional weight problem, usually due to loving all this good food a bit too much. This brother is now probably about 25 lbs overweight, mainly due to some limitations to his mobility these days. The other brother? He has been committing suicide by food now for at least 40 years. He is so enormous that he can no longer get in an automobile - if he goes somewhere it's in an ambulance in a wheelchair. He lives in a nursing home as he cannot properly care for himself anymore. But he can still order in order after order of junk/fast food, all of which he consumes. One brother has myasthenia gravis, prostate cancer and multiple myeloma. Guess which brother is is. NO, it's NOT the grossly obese brother, it's his brother who has eaten properly his entire life and is only a bit overweight, not really much considering his age and overall health. Life is often VERY, VERY unfair...

It's astonishing how much harsh judgement, in all directions, people have about obesity, cancer and who is at fault. It's a multiple-cause problem which can be traced to many things, some as mundane as the current size of dinner plates to the addition of high fructose corn syrup every food imaginable. Obesity is not the natural human condition and it causes system-wide inflammation - hence multiple possible outcomes. But judgements, name calling, holier-than-thou pronouncements - honestly have any of those thing ever helped anyone succeed at change?

I see one of the very top myeloma specialists and researchers in the world and he said that myeloma is absolutely not tied to obesity, nor is it a “lifestyle” cancer. Many myeloma patients gain weight after diagnosis because a primary treatment is intense steroids that make you gain weight. But that’s a consequence of the disease, not a cause. In fact, myeloma is still incurable because they don’t know the cause for sure, though it has been linked to toxic exposure to agent orange, glysophate (round-up), 9/11 and other environmental triggers. It is not food related as even the founder of organic farming and many other “wellness fanatics” in have actually died from myeloma.
Amy M (NYC)
Terribly written article. More young people are getting college degrees and more young people are getting cancer. Correlation or causation? The article offers no insights into specifically how obesity causes cancer, to what degree it causes increases in getting various cancers, if these are statistically significant increases, etc.... I’m sure the Lancet published this information. Why would you leave that core information out?
Chucks (NY)
@Amy M Let me guess,you're applying added scrutiny to this article because it's in conflict with your world view? Obviously the differences are statistically significant- that's why these findings appeared in the Lancet. Also, this is a 200 word Times article, expecting it to describe all the mechanisms by which obesity promotes cancer, a breakdown of all cancers- a little tough to do in this space. If you want to read about how obesity promotes cancer and other diseases, a quick look at the study in the Lancet, WHO reports and others will go into exhaustive detail on the dangers of obesity.

As a formerly obese person (300+ in 2015, 152 now), could it be that obese people are not going to the doctor? I know I limited my contact with my primary when she only told me over and over to lose weight and I wasn't trying hard enough or following the diets she gave me well enough. Fast forward - she had me on diets that were about 1800 calories a day. I would follow her diets to the letter - lose a few pounds then gain it back. I got tired of being called a liar and lazy, when I knew I wasn't. A while back I had my resting metabolic rate tested - it is 967 without any activity - about 1100 with sedentary activity - which means her 1800 was still 700 calories too many for my body to lose weight on. Physicians do not look beyond the two page handout on the Mediterranean diet. For me, what worked was very low carb and high protein - sort of Atkins - and an acknowledgement that there was a magic number for me which was not that of the "average" adult. Metabolic assessments need to be part of this along with determining whether people are carb resistant. For me, carbs are like heroin- now I just don't eat them if they are processed.
Claire (Philadelphia)
Yet again, a newspaper producing TERRIBLE science writing about the obesity issue. The "ties" you are referring to are CORRELATIONS and do not prove CAUSATION. There have been a huge number of changes in the way people live their lives in the past 50 years, which may CORRELATE with obesity. Telling the public that being fat causes cancer perpetuates stigma, and promotes the flawed idea that dieting can help promote health. Diets do not work, with studies showing over and over again that 95% of people gain all the weight back, plus more, after a short period of being a "healthy weight" after dieting. Get it together, Nicholas Bakalar.
alex (Hell!! ...‘s Kitchen)
@Claire if someone changes their diet and loses weight, then starts eating junk again and gains weight back, is that really surprising? “Diets” might not work, but eating healthily permanently does, period.
Claire (Philadelphia)
@alex Dieting through restriction has been shown (in scientific studies) to reduce metabolic functioning, meaning that someone can lose weight by restricting their calories, keep eating "healthy", and gain all the weight back. Dieting by restricting calories does result in weight gain, but it also results in reduced metabolic functioning and throws the body into starvation mode. It's not healthy.
Claire (Philadelphia)
@Claire meant to say "Dieting by restricting calories does result in weight LOSS" not gain... I wish NYT comments had an edit feature!

As a species we were likely meant to breastfeed for several years. This is practice rare in today's America. But breastfeeding on demand is one of the best ways to teach a human being self regulation regarding food. Breastfed kids are leaner adults. Cheap addictive, sugary and transfatty foods are another kind of heroin... that kills you more slowly. Lack of self regulation and lack of attachment-- both very influenced by babyhood parenting practices-- underlie obesity, drug addiction, depression, and a lot of our modern social ills.

Europe bans folic acid and folate enrichment of grains and bread due to the association of too much folic acid with colon-rectal cancer. Yet, the US requires all flour and bread be enriched with folic acid to prevent spina bifida. Wouldn't it be wiser to recommend to women who wish to get pregnant to increase their intake of folic acid instead of making everyone in the US swallow an excess folic acid, which increase the risk for colon and rectal cancer?
Friendly (MA)
@an observer Half of the pregnancy are unplanned/mistimed (not necessarily unwanted), and the crucial period for proper neural tube development is the first 8 weeks of pregnancy, which many women don’t even know that they were pregnant. Therefore, telling women who wants to become pregnant to consume more folic acid is not effective. Moreover, the level of fortification in the US only brings the average intake to close to the recommended level.
an observer (comments)
@Friendly Your intake depends upon how much bread and which cereals you eat. Some cereals are so heavily enriched that some doctors say there should be a warning label on the box to serve children only one portion a day. Some American cereals are banned in Scandinavia because of excessive vitamin enrichment. Cancer cells have vitamin C receptors so excess C help them grow. Americans are led to believe the more synthetic vitamins you take the healthier you will be. On the contrary, too much vitamin and mineral enrichment harms the liver. In the US we are being dosed with excess vitamins and minerals in bottled water, juice, milk, most processed grains all promoted in commercials for their high potency vitamins. The NYTimes did a story on it a couple of years ago.
childofsol (Alaska)
@an observer Bread, pasta and cereal made from whole grains are not typically enriched with folic acid or any other micronutrient. These foods are inexpensive, healthful and readily available in any major grocery store. Although I have not thoroughly researched the supposed link between folic acid supplementation and colon cancer, any link is likely due to a correlation with consumption of folic acid enriched processed foods lacking in fiber. There may be other correlates as well, but there is a strong relationship between adequate fiber consumption and a healthy colon.
Jonathan Katz (St. Louis)
This article seems to be saying that if obesity causes a cancer, obesity causes that cancer. Isn't that tautological?
Sarah99 (Richmond)
Why do we need a doctor to tell you are fat? Just look in the mirror. Buy a Fitbit and get no less than 10,000 steps of exercise a day. Couch potatoes get fat no matter what they eat.
Dr. Becky (York, PA)
@Sarah99 Sarah: Excellent point. And, one of the many that appear to be related to our current epidemic. Any physical activity is good for us.
Bruce (Detroit)
These results suggest to me that the same factors that cause obesity are causing cancer in these patients. Two factors which have increased over the years are the amount of junk food and the amount of sugar in the diet. I suggest that researchers focus on those factors.
bill d (nj)
@Bruce: I don't think they or any other researcher would argue, but the point is that eating the same food, an obese person is a lot more likely to develop cancer or heart disease or diabetes over a person who is more normal weight and eats that kind of food (with the likelyhood being that the non obese person likely eats a lot less of the kind of food we are talking about). It is sad to see people assume that the studies are blaming obese people or somehow demonizing them, when they are pointing out that being obese is a serious health risk in of itself. That is saying if an obese person was eating the right food they would be healthy, but the reality is that the body fat itself causes problems that are well known, the pathways are understood. Studies have compared obese and non obese people eating the same kind of diets , having similar backgrounds, non smokers, etc, and when those are studied it shows that the obese people are a lot more likely to get various diseases.
Jensen (California )
there is a book that said obesity causes more cancer than thin people have cancer. but it also said that fat people survive cancer at higher rates. more cancer is not the same as death by cancer.
Michael (Montreal)
As a traveller and a cook, I love to take notice of the availability of different kinds of food. The cliche about the French being generally well fed and generally fit can perhaps be explained in their markets. The average grocery store in France has only a tiny selection of what we would call junk food, a small shelf or two of potato chips and snacks. Processed heavily salted and sweetened fatty foods are almost non-existent. Enter a Walgreen's so-called pharmacy and you are immediately greeted by shelves loaded with giant plastic barrels of every kind of factory-generated junk concoction imaginable whose only value is to the stockholder of that particular manufacturer. Cafes in France and Italy serve coffee. Starbucks is akin to a caffeinated version of the Dairy Queen. I feel sick to my stomach just watching someone eat/drink the latest dome-topped fat and sugar conveyance marketed under the guise of coffee. Of course there are treats to be had, but they come after a healthy relatively small meal. In Canada we actually refer to American portions in restaurants when we travel in the US. It is shocking. Bottom line: this kind of food production and marketing is new and should be treated as a public health crisis.
Erin (Chicago)
I'm all for people loving themselves as they go through the weight loss process, but the handling of obese people with kid gloves has to stop. Being obese increase the likelihood of a variety of diseases and I am not surprised that cancer is one of them. Losing weight can alleviate a multitude of risk factors. I, for one, was obese less than 2 years ago and started experiencing higher blood pressure, blood sugar, and triglycerides. Furthermore, my thyroid was not functioning properly. Fast forward to today and I am 40 lbs lighter, have perfect blood pressure, sugar, triglycerides, and a normal thyroid. While losing weight may not be the smoking gun to solve all health problems, it a strong start.
Claire (Philadelphia)
@Erin I think you could consider the fact that perhaps the change in your diet towards including more whole foods, less junk, and moving your body more (if that was how you lost weight) could be the reason your blood pressure and other levels are healthier, rather than the weight itself. Many people live a very healthy lifestyle and are still overweight, and have great lab results.
charles macelis (watertown, ct.)
Obesity is a disease usually followed by diabetes , high blood pressure and a laundry list of other non communicable diseases. It's going to take more than a change of diet to fix a problem in this country where 2/3 of Americans are overweight. We are being poisoned by unhealthy processed foods. Thanks to fast foods, we now have an unhealthy generation giving birth to unhealthy babies. Why can't anyone see where this is going?
mm (Oregon)
At 55, I found myself flirting with the obese label on the height weight table. Frustrated that my doctor would never mention my weight, and thinking that it would provide the extra motivation I needed, I asked my doctor to just tell me to drop some pounds. She did. Funny thing happened. When my next annual exam came around, having gained another 5 pounds, I didn’t want to return to the doctor to face my failure – even though I had been the one to instigate the “lose weight” order! Then I discovered what worked for me. It was a ketogenic diet. I set a modest weight loss goal of 2 lbs per week. With the essential (for me) help of a carb tracking ap on my phone, I dove in and began losing weight – without feeling deprived or hungry. I could do this! I was able to maintain my diet while preparing full carb meals for other family members. Even with a few falls of the wagon, after 4 months I had lost 20 lbs. I see some comments dismissing a ketogenic diet as unhealthy and unsustainable. I’ve not yet been back to my doctor. I do wonder what the effect has been on my cholesterol and triglycerides, which were low when I started. I would hope that doctors would support patients who try a ketogenic diet with more frequent monitoring if needed. Obesity is also unhealthy and unsustainable. We all have different starting points, various reasons for our extra weight, and different stressors in our lives. We have to find works for us.
Megan (Santa Barbara)
@mm take your keto to the next level and make it a whole foods above-ground veggie diet with only small amounts (20%) protein and plenty of nuts, seeds, and healthy fats. Healthy nutrient dense carbs in small amounts. Throw in 3-4 hours per week of exercise if you want to kick it up a notch! Atkins keto and anti-cancer, heart-healthy keto are very different diets, but both result in ketosis.
Viola T (San Francisco)
Correlation is not causation. Obesity might be a byproduct of other health conditions, along with cancer. Obesity in and of itself isn't necessarily a problem, since people of all body sizes can have metabolic syndrome. We need to stop focusing on obesity per se and shift to actual health markers.
mc (nyc)
@Viola T exactly... any scientist can tell you that obesity is not the cause of incurable multiple myeloma. However, one of the major treatments for the disease is instense and constant steroids which cause weight gain in patients. Many myeloma patients live extremely healthy lifestyles, but it’s not lifestyle that causes myeloma. That’d be like saying Chernobyl victims could have avoided cancer by eating healthier.
William (Minnesota)
Recommending that doctors assess the weight status of patients seems like a feeble response to the obesity epidemic: some doctors already do that and the ones who don't have their reasons. This kind of article fits into the medical model most often used in this Health Section: Doctors should do more, and more medical research is needed. This model addresses one aspect of containing physical problems but ignores many other contributing factors.
sally littlefield (providence, ri)
I feel that physicians and physician assistants are not mentioning weight or obesity as much these days because of "fat shaming" and fear the patient will not return. So many patients walking into a doctor's office over 35 are overweight that it is epidemic. I could be wrong and I am not a medical practitioner but I do know one woman that never went back after being told she was obese. She died at 52 of a massive heart attack.
Mk (Brooklyn)
@sally littlefield There isn't one person on this earth that does not recognize that they are overweight. Those who are obese know how they stand on the medical charts. Children have to be trained from childhood that food is not love. Because of the difficult times we live in children can no longer be outside doing physical activities so it is the parents duty to teach their children about nutrition for their health now and later. Ignore the unhealthy food aisles, parents be an example for them and yourselves so that you can enjoy your child's future.
Jonathan Katz (St. Louis)
@Mk Our children were always outside doing physical activities. I don't know what you are talking about.
NT (Napa)
@sally littlefield Thanks for your comments. As a primary care provider, I hesitate to plunge into a discussion about obesity because only a small minority will implement and persevere with the lifestyle changes necessary to achieve weight loss. This is the reality confirmed by many studies. Medications may help a little bit. But bariatric surgery and intensive multi-disciplinary support (dietitians, personal trainers, etc) are the only interventions which help a large percentage of patients. So I tread lightly, bring up the topic, but don't hammer on it. Only a profound cultural change which upends the enveloping "food environment" is likely to stall the obesity epidemic.
bill d (nj)
This shouldn't be a big surprise, read what researchers like Dr. Valter Longo has found with the role of diet and longevity, and it isn't a big surprise. Cancer cells feed off of high protein, high fat diets, not to mention the sugar that goes along with this (not just intake, but obesity causes insulin resistance, leading to hig h blood sugar levels). And once someone has cancer, being obese makes treatments less effective, when cells are overfed normal ones are weakened, and cancer cells gorge themselves, and chemo for example if I read the studies correctly, end up killing healthy cells while not being able to kill the cancer cells as well. Not going to matter much, the obesity epidemic is very much tied to the corporate food industry, the corn industry, meat industry, packaged food industry, and even though we talk about the high cost of medical care, we continue to subsidize the very thing causing most of it. Trillions of dollars are going to keep people alive suffering from heart disease, diabetes, cancer and other lifestyle illnesses, if people were eating healthy that number would plummet. Older people wouldn't be on 15 drugs, either.....
Mike (NY)
@bill d. "Cancer cells feed off of high protein, high fat diets" Huh? That is 10,000%, dead wrong. Cancer cells feed off glucose (sugar). You couldn't even be more wrong if you tried.
Ron A (NJ)
@bill d Put the blame for obesity where it belongs, not on industry but on individual choice. Industry will sell you whatever you like. If cookies keep selling then that's what they're going to make. And, you can't say the government is subsidizing Starbucks or Dunkin Donuts, two of the most successful franchises in the US. Everyday, they churn out sweet breads and cakes and sugary drinks. Whose fault is that? No, I would'nt blame the franchises.
Clarence (Brooklyn)
My dad was always a heavy set dude, he was really tall so it kind of "evens out" but he would generally be considered overweight. We tried for years to get him to lose weight and my mother drastically changed his diet. Nevertheless, he's been diagnosed with two (pancreatic, multiple myeloma) of the cancers mentioned in this study. By the grace of God he has survived both, but I can't help but wonder what earlier intervention might have done for him. He finally did lose a decent amount of weight.. all it took was continuous blasts of radioactive energy.
Bill (South Carolina)
@Clarence Medical science cannot make a person lose weight. Only that person has the chance to do so. It is truly unfortunate that the incidence of obesity in the US is increasing and doing so at younger ages. You can blame the parents or caregivers of children for fostering obesity, but as an adult, only you have the ability to change. Apart from the fact that obesity increases the cost of medical care for all of us, I have little sympathy for that population.
Chris (Michigan)
Unless somebody has specific information about an impending bout of famine or generalized starvation, then there's absolutely nothing good that comes out of obesity. Full Stop. I appreciate these articles, but at this point I feel like all of this information is falling on deaf ears. Those who are obese today aren't that dissimilar - in my opinion - than those who continue to smoke despite knowing the potential for complications.
OpieTaylor (Metro Atlanta)
Being in my late sixties, I have noticed so much more of our life centers around processed foods. I have come to distrust our food industry, a profit center which is not about our health. I personally feel the fast foods, the processed foods and lack of activity have created an unhealthy America. I have returned to growing fresh vegetables in my own garden, without pesticides and additives, doing as much as I can to not eat from our "corporate" food industry. I wish we could return to fresh gardens and educate our young about what used to be. Sitting in front of tech devices have not helped our nor my own obesity levels. Michelle Obama had the right idea, involving the young to learn about good health.
SS (NYC)
It is important to consider processed and artificial foods. As many of these foods and refined sugars have contributed greatly to the obesity crisis, going on a diet that uses more processed foods and artificial sugars may also have an increased risk for disease. Maintaining a healthy weight due to a healthy diet made up of whole foods and exercise is what will give the health benefit rather than simply decreasing the number on the scale.
Mike (NY)
Ketogenic diet, folks. Watch The Magic Pill on Netflix.
childofsol (Alaska)
@Mike 1. For disease prevention and longevity, the best evidence to date is that a diet composed of whole foods that are mostly from plants is the best way to prevent disease and achieve longevity. This is the diet that almost all our ancestors thrived on, and there are decades of research involving thousands if not millions of people, supporting the benefits of such a diet. 2. For most people, a highly-restrictive diet is not a viable lifelong eating plan, because it cannot be maintained. A ketogenic diet is among the most restrictive of diets. 2. Low-carb diets, whether keto or paleo, are not sustainable. That is to say, while a few elites in mostly elite countries will have the luxury of eating this way - or any other way for that matter - the world does not; in the real world, nature grows plants, and plants contain significant quantities of carbohydrates.
Chris (Michigan)
@Mike There isn't any one "magic" diet that is going to do the trick for people. Dieting is about *watching what you eat*, not the religious adherence to one narrow type of food at the expense of all others. Just like I wouldn't tell people to "deadlift all day, every day" as their solution to weight loss (despite the deadlift's reputation for total body workouts), I wouldn't tell somebody to just "eat proteins, all day." Variety is the spice of life. Instead of ingesting the whole bag of chips, try a couple of servings next time. Beats having to go on a Keto diet.
MaryTheresa (Way Uptown)
@childofsol Incorrect. Check the work of Weston Price.
Mattias Dürrmeier (Fribourg, Switzerland)
We consume so much of everything, and especially of junk food, that it's starting to kill us. I hope we start doing something worldwide about obesity. It's a serious health problem. I feel like one day, we'll compare the obesity/junk food problem to cigarette, when we discovered in the 1950-60s that it caused serious health issues. This article is already pointing this out, but just like with the first studies around cigarettes, will probably not be taken seriously.
Ron A (NJ)
@Mattias Dürrmeier I'm glad you included yourself in the generic, "we". I'm so tired of people always pointing the finger at someone else. It is a worldwide phenomenon, not limited to certain people or countries, as you say. There will always be long term health consequences to being obese. But, even knowing that, in the short term, we only see the pleasure we get from eating what and how much we want.
