Today: Energy needs and body weight. Part II

There are two things about our feedback control system. The system tends to store a small additional security amount of energy – just in case. Just in case we might find exactly now our prey and this prey is a runner.

So we have to start running after the animal. Maybe 10, 20 , 30 kilometres. After that we have to wait and watch, and once again start running 5 kilometres - until our hunting spear sets the an end to the animals life.

No time to sit down and have a nice lunch. But – lucky – our body stored away yesterday and the day before energy, yes, also in form of the security margin of body fat. Maybe you remember the old days of endurance running.

After a run of six hours the body weight was up to two kilos less (yes, lesser water in the first place) and our waist shrinked up to the width of a palm.

The trap: although we don´t need the just in case energy storage no more today, our body keeps storing. According to our observation a body usually only feels like having had enough food, if we took in 300 Kcal more than we´d need when just sitting around.

The security margin our body is claiming by signaling hunger to built a security margin of energy storage is 300 Kcal a day.

Imagine, you´re just sitting, but you continue eating normally until you feel sated. Within 20 days living a quiet indoor life at our desks we will have stored an amount of 6000 kcal which equals exactly to one kilo of body fat.

So the consequence would be: we mustn´t eat until we are sated? Who does such a thing? Nobody.

Next: Energy needs and body weight Part III. Energy claim of the feedback system to keep the status quo - in any case. And: why do some people need just need the amount of food a sparrow would eat.
