Diet and Hunger with Evolution in Mind

OK, not that anyone cares so much to hear about this topic, but I am going to write about it anyhow. I have wanted to write this little post for quite some time, but I have not had the time.

I have written a little about my little diet experiment in a previous posts having gone from 164 lbs down to 150 lbs, and now after having returned from Belarus (and off the diet) I am back up to 162 lbs. I have been thinking a lot about how my hunger and my desires to eat manifest, how losing and gaining weight happened, as well as thinking about how evolutionary psychology might apply in this situation. I know you are thinking ‘A strange combination.’ or ‘Isn’t there something more interesting he could be doing?’.

The Shangri-la diet crushed my snacking or munchies almost completely. It was such a freeing and wonderful feeling to look at a chocolate bar, candy, or something else sweet and tasty and think ‘I do not need that’ and just walk away. This got me to thinking about how and why we all have these desires to eat things that we do not need to eat, and that may not even be good for you. I have come up with a little theory here. We have 2 modes for eating: the ‘eating to live’ mode and the ‘eating to eat’ mode. The first one is necessary and the second one may serve a purpose that is not needed and perhaps even detrimental in a first world country like the United States.

Eating to Live

This section is going to be fairly short as it will be pretty much self explanatory. The body lets you know that you need to eat by making you feel feint, giving you that hungry feeling, as well as an anxiousness to find food. Once you find food you eat until you do not need it any more. This ensures that you have enough calories to keep on living and allow you to find more food for survival

This provides for you the instincts and feedback via psychological and biological feed back in order for you to stay alive and take care of your bodies needs right now. I have found that while on the Shangri-la diet that I pretty much always decided to eat healthier and chose to not eat unhealthy foods when the ‘eating to eat’ was crushed. I was in much more control of and much more conscious of my bodies needs and the food I ate.

Eating to Eat

The previous one is not so interesting, well this one I find a little more interesting. Eating to eat. Snacking munchies. This part sucks!

So, you have eaten. You are not really hungry and you just have this desire to eat something. You do not have an urge for anything specific, but you find yourself looking through the cupboards or the refrigerator for something that will sate this desire to just eat. This is an annoying feeling that you just want to get rid of.

Now your body looking around and will have you sating yourself on foods that are most likely fattening. You body has food in it and is not really hungry, but now it is moving into fat storage mode since it has time in order to ensure that you will survive longer. Why on earth would you body do that in this world?

Lets think about it like this. Evolution takes thousands and thousands of years in order to make changes. Our bodies and minds are stuck with the instincts and bodies wrought in an old, old world where humans are hunting mammoths on the plains in small packs or tribes. Gathering what fruits they can find as they go. Nomadic tribes who hunt prehistoric creatures. In that day and age humans may go weeks without food and the human body has developed a mechanism to enhance its survival for those lean times. That survival mechanism is the ‘eating to eat’ process. Searching out foods especially fattening foods such as those with a lot of sugar, fat, partially hydrogenated oils, and high fructose corn syrup. Things that when eaten the body can turn to fat and store it for the potential lean days ahead greatly increasing your survivability.

I do not know about you, but in my little town of Baraboo where we have a super Walmart I have never found myself wanting for food or even close to truly starving. This ‘eating to eat’ is an outdated evolutionary psychological adaptation that is causing us so many problems leading us to obesity and other health issues since it is something that is really hard to control for many people. Controlling those urges and allowing ourselves to eat food that is health is not so easy and is a battle that is not easily won when evolution is against us.

Conclusion

I do not have a really profound conclusion for you, just that eating to eat is bad for us. We need to find a way to crush that deep and instinctual urge so that we can eat healthily and happily; to eat to live and not live to eat. The Shangri-la Diet experience helped me do that and it was quite the liberating experience.

In my previous post about this topic I mentioned that I will start the Shangri-la Diet again. I did not then since I was curious where it would take me, but I want to again now. I just need to find a not-so-nasty oil to partake.

Evolutionary Creationism?

I have found a post about the Atheon that provides me with a convenient label for my beliefs on our origin, if you will: Evolutionary Theology or Evolutionary Creationism. I have believed in this way for a very long time and its just nice to know that I am not alone in my thoughts and to have a label for it.

It appears that a man named Michael Dowd pioneered this belief in his book “Thank God for Evolution”“. I will have to pick it up and give it a read.

Monogamy and Medical Sciences Bypassing Advantages of Natural Selection

In this crazy and progressive world that we have here where monogamy is the established “norm” and medical sciences are advancing at a rapid pace and has been for many, many decades, we may find that these two things are having humanity bypassing the advantages that natural selection and evolution would provide.

Natural Selection would normally be able to weed out undesirable traits and mutations fairly quickly (speaking in relative evolutionary terms here) by not allowing them to be passed on to future generation. Monogamy and our Advancing Medical Sciences bypasses this evolutionary benefit.

Monogamy

Monogamy ensures that, with birthrates (55% male and 45% female) as they are, just about all males will essentially have a one mate (assuming an even population density) and that each person will have only one choice for a mate, even if that choice is not as good or desirable as they could possibly have or desire.

The top males will have their choice of mates and the less desirable males will have the left overs. This also means that these less desirable males will all have the opportunity to mate with a less desirable female ensuring that their (collective) less desirable genetics shall be passed on – perpetuating genes that would normally be weeded out due natural selection.

Today’s world with enforced monogamy essentially helps to ensure that “less desirable” mates will be able to find a mate and will be able to pass on their less desirable genes to future generations. This ensures that genetic mutations and abnormalities will be carried on to future generations and it will take much longer for them to be removed from humanity’s gene pool; whereas in cases where natural selection is allowed to run rampant the mates with less desirable traits or abnormalities would have their genes not passed on due to not being able to find a mate, thereby removing defective genes from the gene pool earlier, which allows for a higher quality and healthier humanity sooner than later.

Medical Sciences

Advanced medical sciences help to ensure that people with defective genes live longer and are more able to find mates; and therefore live longer and be more able to find a mate allowing them to carry on their defective genes to future generations, again, bypassing the advantages of Natural Selection.

People that would normally die off due to a severe genetic disease or would be shunned due to physical deformity or weakness are able to find a cure for their health and physical condition and be able procreate due a longer life span and having the indications of a physical abnormality removed or minimized.

Conclusion

Advance medical sciences allow people to live longer and healthier, and are able to hide evidence of genetic abnormalities. Combined with monogamy’s gift of a higher probability of finding a mate make it much more likely that defective genes will remain in humanity’s gene pool longer instead of being weeded out due to no being able to find a mate.

Follow up to ‘Why Beautiful People Have More Daughters”

I like the answers that the book and evolutionary psychology bring to the table. In many ways I can see how their answers make a lot of sense, especially in light of the empirical evidence they provide. Evolutionary Psychology almost seems Freudian in nature, no – not the you want to sleep with you mother side, but everything is about sex side.

I think that they are are trying too hard to be the be-all-end-all definitively answer to all of life’s questions. I think that no specific field of scientific endeavor will ever be able to answer all of those questions. As living creatures we are too complex to be reduced to ‘it is all about sex and reproduction’ for each and every ‘question’ out there. I do believe that evolution is a large part of many answers, but I also think that there are many answers that will be sociological in nature and cannot be answered via evolution.

Just a few random thoughts brought on by this book. Thanks for reading. =)

Why Beautiful People Have More Daughters … (Review)

I have just finished reading “Why Beautiful People Have More Daughters: From Dating, Shopping, and Praying to Going to War and Becoming a Billionaire– Two Evolutionary Psychologists Explain Why We Do What We Do“. Hows that for a really long book title.

This was a very interesting read. This book gives a 2 chapter intro into Evolutionary Psychology and then it is off to explaining many of humanity’s cross-cultural universal behaviors from an evolutionary psychological perspective. I think that this book is a wonderfully enlightening read. I would suggest that everyone pick it up (if you are into that sort of reading). In some cases I think that they maybe trying to hard to come up with answers, but their empirical evidence is telling.

I was previously on the ‘nurture’ side of the ‘nature vs nurture‘ argument, but with the books that I have been reading such as this plus Anatomy of Love: A Natural History of Mating, Marriage, and Why We Stray (Paperback) a (sociocultural look at mating in humans and other creatures) and The Myth of Monogamy: Fidelity and Infidelity in Animals and People (an evolutionary biological look at mating in humans and other creatures) I am seeing that our evolution greatly affects what and why we do things as humans today.
