Neuroscience Explains Why Dieters Rarely Lose Weight (nytimes.com)

HughPickens.com writes: According to a new study, the chance of an obese person attaining normal body weight is 1 in 210 for men and 1 in 124 for women, increasing to 1 in 1,290 for men and 1 in 677 for women with severe obesity, suggesting that current weight management programs focused on dieting and exercise are not effective in tackling obesity. Now neuroscientist Sandra Aamodt writes in the New York Times that "in the long run dieting is rarely effective, doesn't reliably improve health and does more harm than good". And according to Aamodt, the root of the problem is not willpower but neuroscience.

Metabolic suppression is one of several powerful tools that the brain uses to keep the body within a certain weight range, called the set point. The range, which varies from person to person, is determined by genes and life experience. When dieters' weight drops below it, they not only burn fewer calories but also produce more hunger-inducing hormones and find eating more rewarding. If someone starts at 120 pounds and drops to 80, her brain rightfully declares a starvation state of emergency, using every method available to get that weight back up to normal. This coordinated brain response is a major reason that dieters find weight loss so hard to achieve and maintain. According to Aamodt dieting can actually lead to weight gain because dieting is stressful. Calorie restriction produces stress hormones, which act on fat cells to increase the amount of abdominal fat. Such fat is associated with medical problems like diabetes and heart disease, regardless of overall weight.... Aamodt recommends mindful eating -- paying attention to signals of hunger and fullness, without judgment, to relearn how to eat only as much as the brain's weight-regulation system commands.

    There are several whole industries devoted to convincing people that it's as simple as a bit of diet and exercise and if you or someone you know can't lose weight it's because they're fat and lazy. "Health" food, diet plans, pills and potions, exercise machines, surgery. All waiting to grab a dollar. And billions of people too scared or too stupid to know that if they're thin it's their good fortune, not a reason to put others down. Fat shaming is more socially accepted than any other form of discrimination on the planet.

      I'm not sure the statistics presented (the chance of an obese person attaining normal body weight is 1 in 210 for men and 1 in 124 for women) are put in context. What are the statistics for obese people that actually attempt to attain normal body weight? How many lose significant weight but don't make it to 'normal' range? It may not be as futile as those numbers presented would have you believe.

      For one, it does not say that at all and two, this article very much fits what I've experienced.

      Since you're not going to believe ANY of my conclusions anyway, I'm not going to waste my time writing them down.

      Let's just say I'm losing weight now steadily and all I did was I started to chew my food thoroughly... and I mean thoroughly. I counted 60 to 100 chews per bite.

      I immediately started eating way less food because there is now a point, pretty soon, where I find the thought of eating more becomes uncomfortable. I stop eating automatically now.

      So on one side, eating less actually is a viable option IF you eat less because you feel sated. If you eat less just because the scale says so, you WILL get cravings and your body WILL go into starvation mode and you definitely WILL NOT permanently lose weight.

      IMHO the entire concept of "dieting" is flawed; any temporary fix is just that; temporary.
      Unless the changed behaviour becomes the normal (unconscious) behaviour, it will inevitably revert to what was previously normal.

    I think the main issue here is that HEAS and fat acceptance people are overdoing it. Some people can be slightly overweight but everything can be fine health wise and try to force them to a normal weight is more likely to make things worse. There are also some complaints against "fat shaming" that are justified. Obesity is a significant lifestyle-based health issue, but there are many others such as smoking, lack of sleep, drug abuse, risky sexual behavior or being underweight. Shaming should to be fair: If people ignore smoking but are shaming slightly overweight people and claim that shaming is based on health concerns instead of aesthetics that is just bigotry or bad information.

    A little big of overweight (BMI 25-27), especially with low levels of abdominal fat is not a big health issue, it might even be slightly more healthy than normal weight. Something like BMI 27 to 30 is unhealthy most of the time, but on average still causes smaller health issues than smoking. But many people are significantly fatter than that. They almost always have health issues caused by their weight and should really lose weight and could easily do so by swapping some high calorie count items in their diet with vegetables.

    i've never bought into any of the dieting fads nor tried them because they blamed random things without the science to back it up. one fateful day last summer i watched a documentary that claimed sugars in our food were to blame but it actually had the science to back it up.

    Sugar is a drug, addictive and causes food cravings. This begs the question of why we aren't going through withdraw and the answer is that sugar has been added to all your foods specifically so you do not go through withdraw. Look at your raw pasta which has zero reason to have sugar added, it has about 3g of sugar added for every 56g (2 oz).

    To make matters worse, food makers started using High Fructose Corn Syrup in products because it's inexpensive because corn is subsidized. Fructose is processed by your liver and it gets stored as fat unless you have low blood sugar. so products with High Fructose Corn Syrup (HFCS) are most likely to make you fat.

    After removing sugar from my diet (not easy to find products without sugar!) I went through a few days of withdraw. After that, I actually felt like I more energy to do things, so much so that I wanted to exercise (that was never my goal). I started walking regularly and losing weight without any crazy diet, just not eating things with sugar added. Apples are a great source of sugar that have the fiber to balance it out so that it's absorbed slowly avoiding a traffic jam in your liver.

    In the last year I have lost 65 lbs of fat and gained 15 lbs of muscle without ever having to go hungry or restrain myself from eating. I'm still overweight (for now) but I'm no longer obese.

      If I'm a company that makes food, and it was possible to alter my food in some way to make it sell better -- by making it more attractive or addictive or harder to resist, or as the summary suggests, make it interfere with the brain's weight regulation controls -- then wouldn't I do that? If I can encourage or manipulate people (or their brains/bodies) to stuff themselves silly on my food, won't I sell more if I do? I don't even need to know the precise effect of my changes. If I change something, and the product sells better, who knows or even cares whether it's because the change made the food better, or whether it just made it more addictive? The sales numbers will be up either way.

      Anybody that thinks that the companies we buy our food from aren't already doing this is being silly. They have entire research departments dedicated to it.

Installing my own flooring and kitchen cabinets instead of paying someone to do it.
