Crash Diet, Heart, and Diabetes type 2. February 4, 2018

"These diets have a very low calorie content of 600 to 800 kcal per day and can be effective for losing weight, reducing blood pressure, and reversing diabetes," she (lead author Dr Jennifer Rayner, clinical research fellow, Oxford Centre for Magnetic Resonance, University of Oxford, Oxford, UK.) added. "But the effects on the heart have not been studied until now."

Crash diets can cause transient deterioration in heart function

       This diets very popular over all the ages. ADA named it 'starvation diet'. In past Dr. Allen was named Doctor Starvation, or Sr. Death. Why? This was way how he treated diabetes. His patients died.  When he was told that his patient died because of his cruel treatment he answered: who cares, they would die anyway. His most famous patient survived on this diet on 400 but was not able to function independently. She was slow ding. Only discovery of insulin saved her life.
    Now, almost 100 years after we all suggested to reduce our high blood sugar numbers with crashed diets and ADA proudly insist that Starvation diet is Cure for diabetes type 2. Interesting point. Probably high blood sugar number would get down. What about heart? What about life? And anyway, what life it suppose to be if one live on diet 600 calories?

After one week, total body fat, visceral fat and liver fat had all significantly fallen by an average of 6%, 11%, and 42%, respectively. This was accompanied by significant improvements in insulin resistance, fasting total cholesterol, triglycerides, glucose and blood pressure.

       Before jump into wagon, let me ask, diet, what is it?  Diet is what we eat. All what we eat is our diet. According to many med pro publications we eat too much, so our diet is overloaded with carbs and calories. Still, it is our DIET, right?
    Now, normal level of sugar in blood is about 100 mg/dl. It can be a little bit more, or a little bit less, still, 100 mg/dl is normal level of sugar in blood. If it is 30 mg/dl it is low blood sugar level, fatal is actions would not be taken right away. If it is 500 mg/dl, it is high, still, it is not fatal.
    So, when normal diet is 2000 calories in average, 1800 for women and 2000 for man, then 600 what is it? Does not it looks that that amount of meal for adult working man can be fatal if it last too long? It will be. Man would not die right away, but with time it would lead to mortality of man.
     The study, experiment lasted for 8 weeks, two month. Men and women survived for 8 weeks. They lost weight. For how long? What after the study? When studies over what men and women would do, eat 600 calories every day, or return to the normal life style? Really, what studies studied? What they learned? What are the results of the study?

However, after one week, heart fat content had risen by 44%. This was associated with a deterioration in heart function, 3 including the heart's ability to pump blood.

       The same happened when blood sugar is high. Fat started to be burn to provide body with energy to function. Beside the heart there are lungs must consume energy to push the air,  and metabolism need energy too. So, all these energy going from fat stored somewhere. Our body lost weight. One organ never use fat as source of energy. It is our brain. Brain uses only glucose. This is why in brain there are some very small organ with secret insulin, only for brain needs. When there is no energy to function, no glucose or insulin, any one of those components, brain shot down. Coma. If energy injected as glucose, this is the way how keep alive those who on starvation strike, or diabetics, whose body do not secret insulin so insulin injected, human return body return to life. It is good if there is no permanent damage. It is not all the time the case.

      By eight weeks, heart fat content and function had improved beyond what they had been before the diet began and all other measurements including body fat and cholesterol were continuing to improve.

        What really does it mean? The 'continuing to improve' for what degree? If blood sugar dropping then for what level? The same about BP and all body function. If I did understand it correctly, 600 calories can be used as normal diet for adult working man? Is these really true that man can life happily and fully functional on 600 calories diet? Really? When weight loss stopped? On what level? It is easy to put all on %%%%%. But it is real man and woman. We live, work, and suppose to be fully functional. If this is not then diet what for? Why it is important to improve Blood sugar or blood pressure? because of this make us ill, dysfunctional. Does diet in 600 calories solve the problem? Or it is only one problem replaced by another?

 "The sudden drop in calories causes fat to be released from different parts of the body into the blood and be taken up by the heart muscle," she continued. "The heart muscle prefers to choose between fat or sugar as fuel and being swamped by fat worsens its function. After the acute period in which the body is adjusting to dramatic calorie restriction, the fat content and function of the heart improved."

     Acute period can be replaced by healthy living or it can be chronic condition which is more difficult to treat then acute condition. This is what really happened. People cannot live on 600 calories daily meal. We get dysfunctional. So, participants after study would be back to normal calorie consultation. Body returned to the adjustment period and memory will stay, so body will collect more fat to adjust possibility of starvation in future. Weight returned with plus.
     It is already well known fact that after weight loss weight re-gained, and all time with plus.
 Still damage to the heart remained.

 She added that very low calorie diets do have benefits and do not need to be avoided. "Otherwise healthy people may not notice the change in heart function in the early stages," she said. "But caution is needed in people with heart disease."

Say me, what really was first, and what was next? Crushing diet which hurt heart?  Or heart disease which leads to obesity?
