...I mean that we wouldent store fat at every chance we get, just enough to live.
Wait, are we talking about pokemon evolution or real evolution?
Where does the excess fat go? Instead of storing the energy as fat, we burn it...?
What the heck is that? ive never taken an anatomy couse so IDK what that means. If this is something really simple that im just not recognizing, please excuse me.
I tried but the cognitive dissonance made my head hurt.
The only really plausible option is excretion, but that's just a medical disorder. And sort of gross.
Adipose cells divide in order to accommodate higher fat uptake and expand / contract depending on the amount of fat currently stored. As you eat more and overfill your body's supply, the adipose cells divide and make more room, quite possibly an infinite amount, technically. In order to undergo the change you propose, we'd need to either (1) stop taking in fat altogether, (2) stop our fat cells from dividing so we can't store it, or (3) burn the fat as soon as we intake it.
To address these solutions:
(1) This is evolutionary disadvantageous and cannot be controlled. We will be unable to function if we are unable to take in fats after we have hit a certain threshold since fats compose the majority of our energy source anyway. We would burn our fat stores and then have to take in more fat after that, and therefore have to eat more meals than is currently efficient and necessary.
(2) We can't stop our fat cells from dividing. We don't have the biological mechanisms inside our bodies. One way to go about this is to release growth-inhibitor hormones once we've hit the maximum number of cells, but that will also affect the entire body because we've already evolved so much into the body-specific receptor system. Then, this brings up the problem of where the fat goes when we can't hold anymore anyway.
(3) This is a high-maintenance solution with low long-term gain. See below:
When we burn our "extra" fat, where would the excess energy go? Sure we will use some of it for daily use, but the reason why we store fat already is because we use up a great majority of it in our daily trials anyway. We will be more active, but in exchange, we will need to eat a lot more to sustain the body's constant destruction of lipid molecules. Even so, there will be a lot of excess energy that plays no purpose in the body (and there has to be an output for energy anyway, since that's how the body works). If you say to developing the body, then (1) our body system will have to completely overhaul itself and change to incorporate a system that destroys and replaces muscles without destroying them through exercise (you can't just overlay muscle; you need to destroy and rebuild it), (2) therefore, we would need to burn a lot more energy and therefore need to eat a lot more and (3) we would probably die off from lack of food and our bodies will become a lot more inefficient. Moreover, the inherent problem with this solution is that you can't control how much fat is burnt anyway... What if you're completely idle?
