FDA Approves Implantable Vagus Nerve Disruptor For Weight Loss

The L.A. Times reports that for the first time since 2007, the FDA has approved a weight loss device (as opposed to a weight-loss drug), an implantable device called the Maestro Rechargeable System. Using electrical leads implanted just above the stomach and a regulator carried under the skin near the ribcage, the device suppresses signals carried by the vagus nerve. ... The device adopts a variant of a "neuromodulation" technique long used in the treatment of epilepsy: by applying intermittent bursts of electrical current to the vagus nerve, it disrupts the signals that prompt the stomach to relax, expand and prepare for an influx of food. ... The FDA approved the use of the device in adult patients with a body mass index, or BMI, between 35 and 45, who have at least one other obesity-related condition, such as type 2 diabetes.

    That's bullshit. Obese people have pretty much the same metabolism as skinny people. It's not your "metabolism" that makes you obese, it's how much and what you eat.

    No, it really is quite dependent on biology. There are numerous studies on twins that clearly show that it's governed by far more than just calories in == calories out. http://www.gatsby.ucl.ac.uk/~p... , http://www.nytimes.com/1990/05...

    Anything that can seriously help people control their weight isn't a gimmick, it's a fix

    This is closer to a gimmick. And a dangerous one at that.
    From TFA:

    In a 12-month clinical trial considered by the FDA, 38.3% of subjects who received the active Maestro device lost at least a quarter of their excess weight, and 52.5% of subjects lost at least 20% of their excess weight. On average, weight loss in those subjects with an active device was about 8.5% greater than that seen in subjects who received a Maestro electrical pulse generator that was not activated.
      ...
     
    While the cost of the device has not yet been set, Lea said that getting the device implanted and activated will likely cost "somewhere between $20,000 and $30,000"--an amount that is more than gastric banding but less some of the most complex gastric bypass surgery.

    Over a year, on average, it increases the weight loss by "about 8.5%" compared to an implant which was turned off.
    And, it works for about half the people.

    I.e. For the people who have been losing weight through other means, 92.2% of the weight loss is attributable to FACTORS OTHER THAN THE IMPLANT.
    "About 8.5%" increase is about 7.8% of the new total.

    All that at the yet unknown cost of MAYBE $20-30k, invasive surgery and most importantly - randomly fucking about with one's nervous system.
    They are patching-in this implant to jam that same network which we KNOW to be a major neurological pathway and of huge importance "in the bidirectional communication of the gut-brain axis and...useful therapeutic adjuncts in stress-related disorders such as anxiety and depression".

    That thing severing of which causes mice to give up and surrender in stressful situations?
    They are flooding that with jamming signals during the hours when one is awake.
    What could possibly go wrong, right?

    And to achieve what? A sense of satiety.
    Because as we all know, we eat ONLY when we are hungry and we intake food by volume, regardless of the calories.
    100 grams of Nutella and 100 grams of cucumbers is the same to us.
    We just need to get our stomach to think it is stuffed with SOMETHING - and then we will stop gaining weight.

    At least according to the logic behind this "50-50 chance for 8.5% increase in the effectiveness of dieting" gimmick which works by jamming one's nervous system.

    That $30000 spent would be better invested into healthier food and exercise.
    Heck... it's TWO annual federal minimum wages in the USA.
    One could literally spend a year on that money doing nothing but working on their health.
