    How severe was the diet? What does this mean, considering that they

    not. A counter question, if this is the result for two weeks what for
    longer periods? I think I know the answer based on previous research
    involving an army experiement and another a man who went on an amimal

    on his own.

    Low carb diets 'cut heart energy'

    There are concerns about a low-carb diet
    Scientists have found high fat, low carbohydrate diets can reduce
    energy to the heart.
    The Oxford University team say it is unclear at this stage whether this
    could have a damaging impact on health - but say more research is
    needed.

    Many people have lost weight quickly by following such diets - but
    scientists fear they may not be good for health in the longer term.

    The new study is being presented to an American Heart Association
    meeting.

    The Oxford team monitored 19 people over a two week period.

    We would certainly not recommend high fat-low carb diets to anyone
    who wants to lose weight and look after their heart

    Professor Peter Weissberg

    They found that the energy stored in the heart was reduced by an
    average of 16% among those who followed a high fat, low carbohydrate
    diet.

    In some people the energy reduction was as much as a third.

    Their hearts also became slightly 'stiffer' - not relaxing quite as
    well as before the diet.

    One of the participants even noticed he could not manage his daily run
    while on the diet.

    The changes were reversed within two weeks after returning to a normal
    diet.

    Associated with illness

    Lead researcher Professor Kieran Clarke told BBC News that people with
    illnesses such as diabetes, obesity and heart disease also had lower
    than normal heart energy levels.

    A more severe form of energy depletion is one of the features of heart
    failure, where patients struggle with physical exertion because they
    have little 'in the tank'.

    Professor Clarke said further research should be carried out on a
    larger sample over a longer period.

    "Our study gives us some interesting insights into how extreme diets
    might be affecting us.

    "Of course, this is a small and short-term piece of work. The body is
    remarkably adaptive and what we don't know is whether our hearts would
    have gradually returned to normal had we stuck to the diet long-term."

    The British Heart Foundation, which funded the work, said the results
    reinforced their view that people should not follow high fat, low carb
    diets to lose weight.

    Professor Peter Weissberg, BHF medical director, said: "Diet devotees
    can be reassured that this research in no way suggests that the high
    fat-low carb regime is going to give them heart failure.

    "However, they should be aware that such unbalanced diets are a major
    insult on their bodies' metabolism and, as this study shows, may be
    having direct effects on their hearts, particularly since they tend to
    be high in saturated fat.

    "We would certainly not recommend high fat-low carb diets to anyone who
    wants to lose weight and look after their heart.

    "Achieving this with a balanced diet and regular exercise is
    sustainable for life and, for most people, is the safest way for your
    heart."

    1) The study is not published, it is being presented to the American
    Heart Association meeting. The AHA has shown to be squarely against low
    carb from day one. They have been shown to have an agenda against
    low-carb.

    Here is what CSPI has to say about the AHA.

    http://cspinet.org/integrity/nonprofits/american_heart_association.html

    enuf said 'bout the AHA.

    2) "The Oxford team monitored 19 people over a two week period."

    NINETEEN people over TWO WEEKS adds up to absolutely squat. It is hard
    to believe that serious scientists would even consider presenting this
    to anyone without being completely embarassed out of the profession. Is
    this a joke? It must be, but April Fool's day was months ago.

    3) "They found that the energy stored in the heart was reduced by an
    average of 16% among those who followed a high fat, low carbohydrate
    diet.

    In some people the energy reduction was as much as a third. "

    Did they establish that the reduction was undesired. Maybe the
    initially elevated energy levels were undesired. What did they mean by
    energy stored? Glycogen levels? All muscles store glycogen. On a high
    carb doet the muscles will have to store more glycogen. Is this
    desirable? We don't know. Is the reduction in stored energy desirable?
    We don't know. Should we be alarmed either way? We don't know.

    4) "Their hearts also became slightly 'stiffer' - not relaxing quite as
    well as before the diet."

    Is a "stiffer" heat undesirable? Is a less "stiff" heart desirable? We
    don't know. Maybe our heart are too soft from too much refined carbs in

  5. This was a 2 week study. The first two weeks of transition into or out of
    ketosis has side effects. They needed to wait until the dieter had adjusted
    to the new way of eating.

    You are an idiot with no credibility. Same cast of characters only
    with the results you want and everything would be fine.

    You act just like the Weston Price cult in that they attck the CSPI in
    one area and then use them to support their claims in another area
    i.e. refined sugar is bad for you.

    From someone that enjoys endurance running, studies have shown exercise
    and low carbs are oil and water and yes past the ketosis cycle. Low
    carb, and I'm not talking about cheap sugar [censored], does not provide
    enough energy. You may lose weight on LC but that says nothing about
    health. Hell you can lose weight on all those asinine fad diets.

    If an eating regimen will not keep the exercising body with enough
    energy then I find the diet is detrimental to healthy living. Proper
    eating should keep you healthy from sleeping through the Tour de France.
    Does anyone think people like Lance Armstrong, Yanos Kuros or simple
    marathon runner are low carb? Then again some people think simple
    exercise is egregious and will not control weight.

    Actually I shocked that this summary article even raises an eyebrow. Low
    carb and exercise has been known for years to be a disaster.

  10. Ignoramus, who posts here occasionally has run a half marathon on low carb
    with no ill effects.

    There is some anecdotal evidence that a runner who lives in ketosis never
    "hits the wall."

    No disrespect to Ignoramus but his effort was a bit above a walk. If he
    had tried to really run it, he would have found the wall real fast.

    It has to be anecdotal because the science and reality says it aint so.
    You can't do exercise short of a casual walk in ketosis or LC in
    general. Many people that start running to lose weight try Atkins and
    running at the same time. They want to hurry up and get svelte. They
    soon come into the running forum wondering why they have no energy and
    feel like [censored]. Once they return to carbs they get their energy back and
    lose weight as long as they keep their caloric intake less then they
    burn.

    In fact the big problem with surviving endurance exercise, is make sure
    you get enough carbs or you end up in the medical tent.

    If you have to minimize you exercise because your body does not have
    enough carbs, tell me again how healthy LC is? There is and old saying
    listen to your body. If your exercise is the TV remote control, you
    haven't got the foggiest idea about exercise and nutrition.
