"the prisoners at Auschwitz were getting at most between 1302 and 1744 calories for 24 hours. 1744 calories daily represent a little less than the basic conversion of food into energy of a grown man, or in other words a little less than the amount needed by a man resting in a lying position, covered and motionless. A man who works, nourished in such a way is burning up his own tissues in order to cover the amount of energy expended. This inevitably results in the wasting away of his organism in a manner dangerous to life."
I inputted my age, height, weight and sex, (I selected the online sex change button a few times to see if it made a difference and ladies its worth considering a sex change to get a little more ration allowance). I selected an activity of 'lightly active' as I'm kinda injured at the moment, but crutch walking is pretty tough going. It recommended that I consume 2270 kcals a day to remain at my current weight. I personally think this is a bit low, and if you've read my previous posts I'm sure you'll agree.
They state that, "The key to effectively managing your weight is all about balance: calories in versus calories out.", which I've discussed in the past to be an absolutely useless statement that is always taken out of context. Let's look at what it means, "managing your weight is all about balance: calories in versus calories out." I completely agree that in order to manage our weight our metabolism need to balance the books and ensure that what goes out, must equal what goes out.
So despite getting that bit pretty spot on they then go on to suggest that, "if you want to lose weight by burning off excess body fat, you should aim to eat 500 fewer calories less than your daily caloric needs". That is a serious deprivation which leads to semi-starvation as discussed in the posts I've mentioned. It also puts me at 1770 kcals a day, which once again isn't far of the Concentration Camps Diets. I've been down as low as 1800 kcals before and the symptoms, (depression, anxiety, skin problems, learning difficulties etc) aren't pleasant. You're right there are millions amongst us, surviving on low calorie diets, and many also surviving on very low calorie diets. However, when yo look at the symptoms and the basic physiology of the human body, that is all they are doing...surviving and not living a life.
