Very sloppy writing. People diet, they lose a bit of weight. People stop dieting, they put the weight back on again.

The fundamental problem is the abundance of overly calorific food in many societies which the final comment hints at, ever so gently. People want a quick fix but there is no quick fix for the problem of over consumption except eat less.

This is confusing...if you only eat X calories per day and exercise, you will lose weight, and permanently (assuming you don't give up), is this more of a mental thing they're talking about?

You say exercise. Exercise has small affect on weight loss for some people. It is recommended because of other positive benefits.

Earlier quoted context omitted.

40 years ago people were born from thin parents, today they're born from obese parents. This has to have an effect on the genetic makeup of the children.

My biology is pretty terrible, but I'd argue that it takes more than just one or two generations to permanently change the genetic makeup of a population. To be more precise: I know there are animal species that changed their natural colors to grey-ish tones nearby the cities in less than 100 years, but that seems to me more a result of selective breeding: the non-grey individuals were eaten/killed, so in a relativel…

I think (or hope) he meant epigenetics. There's increasing evidence that epigenetic changes in parents can be passed to, or at least cause other epigenetic changes in, children, in an almost Lamarkian way.

However, I think the article is saying, "In the long run, for whatever reason, statistically speaking, 95% of people revert to their high water mark of weight, nullifying their previous efforts at weight loss." This strikes me as utterly uncontroversial, aside from our widespread want to be among the 5%.

And my personal take: willpower can win battles, but our central tendencies usually win the war.

There is more than just DNA. The state of a pregnant mother can have an important impact on the offspring even if it doesn't affect its DNA. The same DNA can create different persons because of different gene expression. This is what epigenetics is all about.

Mother obesity affects The brain and metabolism of the baby. This includes the way fat is managed. This is even before birth.

"We are biological machines" I tend to disagree with this definition. The function of a body might look like a 'machine', but that machine is made of trillions of small living beings (cells), all having the same properties as the larger organism - they need to breathe, eat and drink, they age and they multiply and each cell is a very specialised 'machine' in itself. So if you want to call the body a 'machine', then c…

Cancers, cardiovascular diseases etc. are the consequence of humans living long enough to develop them, thanks to modern medicine (tinkering with nature and our bodies).

Low success rates do not necessarily imply that losing weight permanently is futile or impossible. All that we can reasonably conclude is that the majority of people trying to lose weight are using inadequate methods and/or are unable/unwilling to adhere to their chosen method. Consider the following: -The ideal client for a health-club or gym is someone who signs up for a full year on January 2nd and then never retu…

Real world anecdote:

I recently discussed with a friend getting them some exercise equipment as a gift; at first we were targeting specifically "training that might help with keyboard RSI," but I soon realized that the biomechanics of RSI meant that a really comprehensive solution would have to involve exploring all over the body and figuring out where the real weak points are and training those, not just "around the wrist" - so grip trainer type equipment wouldn't be sufficient. It would have to be seen as an "overall fitness" type of problem.

This led me, of course, towards free weights and a training program of general experimentation. But a small free weight set in the home can be a frustrating experience with no space or supporting equipment like benches and racks, plus the chore of reloading dumbbells with light weight constantly. My friend was rightly concerned about whether it would work out for her.

So I reconsidered and landed on resistance bands. They're kind of unfashionable now - and for certain things having barbells and dumbbells and plates would be a lot better. But they store and transport easily, have essentially zero setup time, and there's plenty of exercises for them, many of which are straight-up adaptations of free weight movements. The more expensive Bodylastics set that I ended up buying, which was still only $70, allows for an enormous amount of resistance too. After doing that shopping, I kind of want to get some for myself too.

My friend probably would have been lost at the first step because it's not like anyone marketing fitness actually tells you what you really need to begin addressing a problem. Neither will they explore whether the thing you buy is going to fit into your lifestyle. It's pretty gratifying to realize that some cheap rubber is best for the job.

I must say that I've been the 5-2 diet (intermittent fasting) for nearly two years and It has worked for me. http://en.wikipedia.org/wiki/5:2_diet

> In 2010, H:MC21 organised a lobby of over 250 homeopaths and patients, and handed in to No. 10 Downing Street a letter and the declaration "Homeopathy Worked for Me" signed by 28,112 people.

This article is full of BS. 40 years ago the majority of the population of the US or North Europe was thin. This has been so for the entire evolution of the human species. People 40 years ago did not starve. They just ate things that refrigerators and mass industrial production do not preserve well, like vitamins, or fiber, or natural fat(like butter). Now, when most people eat mass-processed foods, odd things happen…

The article is about difficulty of reversing obesity, once you become fat. Different problem.

It is not about reversing obesity, it is about long term weight reduction. Different problem.

This is not always true. Certain diseases, e.g. PCOS (Poly Cystic Ovarian Syndrome) and (general) insulin resistance mean that eating X calories (assuming X is lower than the calories expended on exercise, and basal metabolic rate) will just make you extremely tired and unproductive. In these diseases, the body is unable to utilize the energy that you are consuming and unable to burn the energy you have stored already.

I'm not suggesting that all causes of obesity are related to a disease, but things are definitely not so cut and dry as expend more energy than you consume and you will lose weight. The body is an exceedingly complex system of chemical reactions which are fairly tightly regulated (see topics around MCA - Metabolic Control Analysis, to understand how systems of reactions don't behave intuitively). Changing one input variable does not always yield the result you are looking for when you simplify the entire human metabalome down to an equation of calories in, fat storage and calories out
