Why do you think they will die by such a drastic reduction in food, when obese persons have waterfasted for one whole year without any food at all?
The human body can, if necessary release around 1% of stored bodyfat per day. So an obese person that carries 300 lbs. of stored bodyfat may get 3 lbs. or around 10.000 calories per day from stored bodyfat - if necessary! A person with only 10 lbs. of stored bodyfat will only release around 0.1 lbs. or 45 gram of stored bodyfat or 400 calories. In the last case, I suppose, there may be a real danger of starvation on a low calorie diet and especially if physical activities are involved! So, what physiological reasons would make a person with more than sufficient bodyfat starve to death then? Why do you think so? Maybe some can get sick or even die of stress or fear of not getting enough food, that’s a possibility, but inside the camp we have a very professional staff to make them feel secure and occupied with everything they want – just no other food than in the prescribed 500 – 700 calorie diet, that gives them at least 100 gram of protein, essential fatty acids, enough fibers and also a multivitamin pill just in case…
