Overweight people are now a global problem

That has been found to not hold up over time and so people seemed to explain it by culture: The US was fatter, because we sit in cars all day; in most other countries you have to walk considerable distance every day, even to use transit.
Now that, too, seems to be failing the data, as other countries become fatter without any notable shift in how they get around town.
It may be time we studied to what degree the worldwide spread of obesity maps to the worldwide spread of industrial food products.
Could it be the 'lag' between obesity becoming a problem in the US vs the rest of the world was nothing more than initial cultural resistance to processed food wearing down over time?
The question of how an individual can lose weight is pretty well understood (if difficult for many to practice).
The more interesting question is what enables entire cultures to surrender their previous generation's habits seemingly en masse.
From reading discussions and articles about it that pop up here from time to time, and also from talking with my family and friends, I'd disagree. What I actually perceive is that in discussions about loosing weight:
- a) people generalize personal anecdotes,
- b) there are dozens of popular diets, and people usually quote their favourite,
- c) whatever Real Science gets quoted, will soon be challenged by another paper saying something opposite,
- d) people try to reason from common sense ("surely if you eat less X you'll be less fat, because X does this-and-that"); I was a believer of the thermodynamics-like theory that deltaWeight = weight + (calories in - calories out)*stuff; many a post on HN convinced me that it's not true, even though it sounds much more obvious than typical dietetary nonsense you'll hear from your random friend.
I'm against blaming everything on people being not determined or hardworking enough. For one, it's wrong attitude (any system that assumes strong willpower or moral high ground from people will fail because of human nature; it's better to engineer around it), and secondly, there are indications that the same diet/exercise combination executed with the same determination will have great effects on some, moderate on others, and zero-to-negative on few unfortunate people.
That doesn't make it any easier to determine what calories out happens to be for a given person on a given day. It does mean that a reasonable estimate can be made and evaluated against a well tracked dietary intake (but well tracked there has its own set of problems).
I'm personally a tiny bit incredulous anytime someone mentions that they've tried cutting calories, but with no results. I've always wondered how they continue to get an energy surplus in the absence of input. These seemingly perpetual motion machines would be of great interest to science, I'm sure ;)
Of course, this is why any good diet needs to be coupled with an exercise program.
Even better, increase your caloric intake, switch to a high-protein diet and start lifting some heavy weights. Muscle creation is metabolically expensive, and muscle maintenance uses a lot of calories. Furthermore, even though muscle is heavier than fat (omg you may gain weight!) it looks a lot slimmer and more fit.
Moral of the story: lift weights, eat protein, get fit, lose "mirror" pounds (even if you actually put more mass on)
Example discussion I pulled out of google:
Like doing big-O notation, there are constants that get factored out. Some people have a higher or lower base metabolism, or respond differently to exercise.
You're not proposing, though, that it's possible to maintain or gain weight at a calorie deficit? That would be magical.
If it's not true, then not eating shouldn't kill us, and anorexia isn't an illness. Have you tried to stop eating? When I tried to wean myself off food, I lost 12 lbs. I'm completely serious -- I went for a week without solid food, taking in only 32oz of soda and 24oz of beer per day (while not working).
I'm absolutely convinced that you would get an adequate fit starting to study very "standard" nutrition books and understanding what you're doing.
"Losing weight" is a concept that must be absolutely removed. Boxers for example lose a couple of kg in a very short time before being weighted for matches. Does this mean they successfully got a better shape? No. Study, and you will understand how things work.
"Losing weight" was absolutely necessary for me, and it will be for most people -- unless you're suggesting that humans can be healthy at 5'11" and 260lbs, or 5'5" and 210lbs -- but that seems too unrealistic.
What I learned of nutrition (after that experiment) taught me that most of what's in bread, pasta, fruit, etc is cruft. Most "health" food is just more empty calories in a "healthier" package.
HN is a place that may be full of people who's brilliant in their field, which unfortunately #1) has nothing to do with fitness #2) it's correlated with being "not exactly fit", so certainly this is not the right place to establish beliefs in the fitness field.
Yes, they may need to do much more activity and eat much less food or in different ratios than others to see results, but that doesn't change the fact that the same algorithm is: 1. the only known way to make progress, 2. well understood.
I was trying to sidestep the very issue (and same old tired conversation) you're trying to avoid: blaming individuals.
Because while it's arguable that a given hypothetical person might be overweight due their own choices and failings, it's next to impossible to argue that massive society-wide changes in health, in a single generation, are simply the result of huge swaths of a society all making the same bad personal decision, all at the same time.
Plus so many of our foods here are processed, including almost everything having cheap sugars in them, that it cannot be healthy.
I have no evidence to back it up but I would think the spread of obesity can possibly be tied to the spread of industrialized processed foods, just as you say.

Further, your chart shows that meat consumption went down (13.3% of diet in 1909-19 to 8.2% in 2004), whole milk consumption switched to lowfat milk and cheese, green vegetable consumption dropped, butter dropped (4.4% to 1%), lard & beef tallow consumption dropped (3.8% to 1.4%). These animal fats were replaced by salad and cooking oils (vegetable oils), going from 0.7% of the diet to 11.1% of the diet.
Basically, while total carbohydrate and cholesterol consumption remained the same, Americans began eating more sugars and less starches and ate less animal fat and more vegetable fat.
My concern is much more for the latter.
Paleo-fans may well have a point about whether flour and such is less healthful than raw plant matter. But that difference didn't seem to manifest into a society-wide weight problem until industrially packaged food gained wide circulation.
Not even the achievement of food-security or the introduction of 'fast food' aligns with the obesity problem like the massive increase of consumption of ready-to-eat types of foods.
Including, notably, chain restaurants peddling industrial foods, displacing local restaurants cooking from scratch (or at lest more often from scratch, or from a place much closer to scratch).
all grains
potatoes
all bread
pasta

most processed foods
sodas and other sugar laden beverages
I now eat meat, fish/seafood, dairy, fresh fruit, and fresh vegetables, with a focus on making sure that the carbs I do get are mostly low glycemic load carbs, and that the sugar I get is part of something (fruit,milk) that requires digestion for the sugar to hit my bloodstream.
Living Low Carb makes a strong case that the "fear fat" campaign is, indeed, utter bullshit. And given how damaging sugar is to your body (excess blood sugar contributes to so many maladies it's ridiculous) I'll take my chances going low carb / high fat & protein.
But if the goal is to lose weight, exercise alone can be counterproductive, because leads people to think that slacking off in the gym for half an hour will offset that supersize menu that they will eat afterwards...
Changing (permanently) eating habits should be the first step and the final goal.
That word "permanently" is really key. It's sad to watch people say "Oh, I can't eat that now because I'm on a diet. But in two more weeks..."
My point is that maintenance becomes simple once you get used to eating less. Eating the amount you used to eat before now seems like a terrible excess (and I wasn't even overweight before).
This honestly surprised me once I started trying to lose weight. I assumed it be a constant war with my will power to not gorge myself. After about two weeks of a very restricted diet, the desire to eat a lot, and often, just kind of drifted away.
I now feel super lethargic if I eat a big meal. I prefer eating a couple small meals through out the day. "Eat not to dullness," and whatnot. Your average fast food meal is now a pretty big amount of food for me -- I used to eat the stuff twice a day, and still want more.
By education I don't mean college level stuff, I mean basic home skills and life skills education and instilling an understanding that fast food/sweets/crisps etc are fine in small amounts but that decent fruit, veg and fresh meat are the staple to a healthy life. Again, this doesn't need to be super complex, there isn't some sexy problem to be solved here, it is just basic, old fashioned food understanding etc. Think Jamie Oliver's Food Revolution type thing.
Also, this is something where governments also need to step up and educate. Free market ethos is fine but preemptive measures don't sell or make money for business so the governments need to fill this gap.
I don't know what the solution to the problem is. But if you do, you will be rich. Something has to change, globally: either our lifestyle or our bodily engineering. And changing lifestyles is not an easy thing to do.
evolution didn't magically stop.
Technological progress (and life style changes that follow it) has outpaced whatever biological processes of adaptation there are by many orders of magnitude.
No, no, a million times NO. At least in the US, the government already "educates" people about nutrition, and most of what they're pimping is horrible, horrible advice. I don't want some agency stealing my money, and then using it to teach me shit that's ultimately killing me.
e.g. You don't stop industrial pollution by educating Americans to not buy products that were created by factories that pollute. You stop industrial pollution by enforcing reasonably safe waste disposal methods, so those costs are reflected customer-facing prices. (And thereby also encouraging free market advances in disposal and production technologies.)
So why would you try to combat an obesity epidemic by attempting to educate people to not buy sugars? You simply identify the problems ('cheap' sugars in processed foods, huge portions) and ensure the costs are reflected up-front in the price (yes, a sin-tax on junk food and absurd portions).
Or, at the very least, stop government subsidies for the production and use of things that we know are contributing to the problem. (cheap corn->cheap HFCS->cheap sugar in everything)
"I believe that the solution to this problem is exercise, and those who would like to decrease their weight should try different sport activities."
What about eating healthier? That strikes me as a more effective and maintainable solution.

Though its a small sample and an extreme one at that, the contestants' diets accounted for approximately 65% of their weight loss.
For losing weight. For health in general, both seem about equally important. (And lots of exercise will allow you to get away with a crappy diet much easier.)
unfortunately, it's too easy to speculate on diets sitting on a chair.
This is supposed to be a list of "facts" but in reality, the "sugar is addictive" hypothesis is still, well, a hypothesis.
>that the government is scared that there will be political unrest if the price of sugar goes up
It's the Chinese government. "Scared that there will be political unrest if X" is their default state for any untested X.
I took addictive in the sense that we are "addicted to oil."
What makes no sense to me whatsoever is to try to extend this analogy to sugar.
Consumers seek to maximize the taste/cost ratio where cost = the monetary cost of food + time to prepare
Sure you can eat healthy for cheap if you're willing to eat things that are not that tasty or if you're willing to spend time learning to prepare foods and then preparing them on a regular basis. I'd really like to see the economics behind that - like most things, stuff produced in mass is "cheaper" than stuff we make ourselves, maybe not in terms of monetary costs, but definitely in terms of labor savings.
The tastiest things tend to pack a big caloric impact, which makes sense from an evolutionary point of view.
Cheaper tasty calories lead to greater caloric intake, which often occurs at the same time an economy is shifting to less labor intensive work. This creates a perfect storm where caloric expenditure is declining at the same time caloric intake is increasing, leading to an obesity epidemic. It's simple physics, conservation of energy/matter. The energy intake of humans increases, but their expenditure declines, the surplus has to go somewhere. That somewhere is our fat stores.
My first thought was they are exerting too much pressure on the surface of the world and endangering the integrity of the crust... need to get out more...
I've just moved from Perth, Australia, where it is pleasant enough almost every morning to just to throw on shorts and a top and go for it.
I'm now in the UK. Getting a face-full of road spray and having to manage your temperature (ugh it's cold, no wait now I'm moving it's hot) and try not to get drenched in either rain or just condensed sweat is frakking NASTY.
I'm also based in the UK. Cambridge to be exact. I commute by bike in any weather. English weather is actually quite tame.
2. Are you sure you don't mean "hard to find 1 morbidly obese person everyday? You do realize that a BMI of 30 or greater is obese, right? And In non-tight and non-revealing clothes, you probably aren't even going to be able to tell a person with a BMI of 30-35 is obese. But they are according to studies like the linked article refers to.
For instance, this guy is obese (BMI of 30.7): http://www.cockeyed.com/photos/bodies/511-220.html
And this guy is overweight (BMI of 26.2): http://www.cockeyed.com/photos/bodies/603-210.html
I'm pretty sure a BMI of 30+ is still not the healthiest. Just not as obvious as a person with a 40+ BMI (morbidly obese)
Believe me, you don't think all that well either - decisions become more emotional than rational - so getting out of the hole gets even harder.
Instead of finger pointing, chastising and instructing, I think more compassion is required when it comes to dealing with the complex issue of obesity.
1. Eating healthily is more expensive than eating junk
2. Eating poorly impairs your ability to think to the extent that you cannot be held responsible for your poor choice of diet
I find them very hard to believe (even though I hear them often). Do you have any links to the studies or evidence that show this?
This assertion is blatantly false. I can get full on excellent quality food for about the price of a mcdonald's meal + a bag of chips.
I've eaten like crap, and I've eaten well. It's very cheap to eat healthy. Most people are just making excuses for not wanting to practice self-control or educate themselves.
Not that kind of junk. Think ramen noodles.
Everywhere I look, fat is cheaper than protein, white bread is cheaper than whole-grain multigrain bread, white rice is cheaper than brown rice, a pack of sugar is cheaper than the same weight in fresh fruits and veggies, and a bottle of sauce made with nothing but salt and MSG is cheaper than a bottle of sauce made with natural ingredients. When you need to feed 2 teenagers with a budget of single-digit dollars per day, every penny counts.
Assume that healthy food is $2/serving and 400kcal/serving.
Assume that you need 2000kcal/day.
A healthy diet costs $10 for "just enough calories". An unhealthy diet costs only $4 for the same calories. If you ate 3000kcal/day, it would still only cost $6. So yes, it can be cheaper to eat a lot of unhealthy food than to eat only a small amount of healthy food if the price differential is large enough. It's also easier to overdose on unhealthy food because the calories are so concentrated. A second bowl of ramen can contain 400 calories. A second head of lettuce might only have 40 calories.
Of course, you might face a million-dollar loss 20 years later because of heart disease, but would it really enter the calculations of a single mom with a weekly grocery budget of $35?
Having lived in both incredibly poor neighborhoods and incredibly wealthy ones, I'll say this:
It's possible to eat healthily in poor neighborhoods, it takes a lot of work - a lot more work than it does for a wealthy person living in a wealthy place. I've observed this in myself: I gained enormous amounts of weight while living in a poor, working-class neighborhood, and promptly shed it once I moved to a wealthy upper middle-class neighborhood. I've bounced back and forth between poor areas and rich areas since then, and the pattern has so far held up.
But, anecdotes not equivalent to data, etc etc.
In a upper-middle class neighborhood healthy diets practically come after you with a baseball bat. It's steeped in the general consciousness of the area, support by people who possess the freedom of finance, time, and effort to think about such things, and it's supported by the merchants in the area.
The same is not true in poor neighborhoods, where fast is king to a population of overworked and tired people. When you're holding down multiple jobs and raising kids at the same time, the CSA subscription may be cheaper and healthier, but it also requires time you don't have. Merchant offerings in the area reflect this reality, and so even someone with the intent to eat healthily will find that availability of healthy food is substantially lower.
We are fortunate in that we have the resources with which to abstract many annoying details away from our lives so we can concentrate on the important things: good bodily health, mental well-being, and the such. Most of the population isn't so lucky.
Though the relationship appears to have weakened in recent years:

This seems only incredible because you don't understand the mechanics of being poor.
Contrary to popular belief, the main bottleneck of being poor is not access to food - the market has solved that part remarkably well, and farming improvements throughout the last century (Borlaug is perhaps rolling in his grave) means that food in general is so cheap that everyone in a developed country has access to it.
The main bottleneck of being poor is time.
A poor person spends considerably more time just to ensure survival than a wealthy person, and has remarkably little "disposable" time remaining in a day. Long, irregular hours, possibility of multiple jobs, lack of access to speedy/on-demand transportation, lack of access to time-creating conveniences (laundromat far way instead of laundry in the house, for example), all serve to make time the rarest resource for the poor.
That's not an exhaustive list by the way, and I don't pretend to know the full exhaustive list.
All of this means that the poor gravitates towards fast, low-effort food, and the rest makes sense.
In any case, if you're poor, your time is cheap. This doesn't jibe with the claim that the poor lack enough time to, say, cook healthy meals for themselves. Poor people 100 years ago were poorer than most poor people today, and yet they largely cooked for themselves—and they were much thinner.
What accounts for this change? My suspicion is that it's dependence without responsibility. A hundred years ago, private charities (which are accountable to their donors) were in a position to hold recipients of their largesse responsible for their actions. But such charities have now largely been displaced by government agencies. These agencies have been captured by special interest groups,† and charity has mutated into entitlements. As a result of receiving benefits without accountability, the poor have lost much of the knowledge needed to be self-sufficient, which motivates further intervention. It's the law of unintended consequences followed by iatrogenic escalation.
†These interest groups are not the poor themselves, but rather those who speak for the poor. I think it's no coincidence that the former tend to vote for the latter. Political patronage is one of the oldest plays in the book.
I'd guess you'll find the above narrative unconvincing, but I like how you think, so I thought it was worth a shot.
This is true, but not a very useful thing to say. Trivial observations of others' moral failings are often a way for us to feel better about ourselves and our choices, but such statements are not solving the problem.
The first part of #2 is true, but the latter part is more a moral or philosophical question.
You appear to have fallen into the trap of believing that the concepts of compassion and personal responsibility are at odds with each other. American politics have been poisoned by the same idea, and it's a real shame.

You can live healthy on little money. But most people don't want to eat that kind of food. (George Orwell made a similar observation.)
Potatoes are actually pretty healthy.
