Is food addictive part 3?

Last week I did two blogs on how certain foods can be addictive and how we have a hereditary predisposition for wanting to eat foods with lots of calories. I also mentioned how we really don´t have strong instincts to engage in physical activity because, before in the past, physical activity used to occur automatically every time we needed to hunt. No one would just go for a run and waste precious calories, we needed all the calories we had. Now, everything has changed. It´s easy to get food and we barely move, and those are two of the reasons why obesity is a WORLD WIDE EPIDEMIC.

Well, in this third part of ´is food addictive´, I’m just going to mention some facts that most people don´t know and should, and that I consider pretty important. So let´s start off.

  1. Did you know that the last 10,000 years of our history only represents 1% of  human history? The body changes and adapts over time but it usually takes thousands of years for that to happen. Agriculture first arrived 9,000 years ago, if you think about it, in terms of human evolution, that´s not a long time ago.
  2. Before agriculture we were hunter-gatherers. Fossils records show that Paleolithic hunter-gatherers lifespan averaged 26 years, but with the invention of agriculture the lifespan went down to 19!!! (1)
  3. In Greece and Turkey, near the end of the Paleolithic hunter-gatherer era, men averaged 5´9 (175cm) and women 5´5 (166cm). By 3000 BC, with agriculture a way of life, the average height had dropped to 5´3 (161cm) for men and 5´ (152cm) feet for women (1,5). This could be because the Paleolithic hunter-gatherers ate hundreds of plants and animals, supplying lots of complete proteins and vitamins. Farmers ate mainly three crops, wheat, rice and corn, because they were the easiest to cultivate, harvest and store without spoiling.
  4. Human milk matches the exact proportions of amino acids and fats used for brain circuits and contains antibodies to prevent infections. Cows milk contains very different proportions of amino acid and much more fat. Babies fed on breast milk average 8.3IQ points higher by the age of 8 than those fed on milk-based formula.(3)
  5. Predators consistently have larger brains than herbivores. You require more cunning to catch prey than to find the next leaf. Omnivores, who must switch between these tasks, tend to have larger brains yet.
  6. Brains and nervous systems are for mobility; plants don´t have brains, animals do. Exercise especially generates neurons in the hippocampus, an organ associated with memory, and these new neurons have been demonstrated to enhance learning. What I´m basically stating here is: MOVE, it will make you smarter.
  7. Dieting, in the long run, almost never works! Maximal weight loss is typically achieved at around 6 months, followed by weight regain.(2)
  8. Evidence has been building up that if you consume less calories, far below that needed to maintain normal weight, but still consume vitamins, protein and other important nutrients, your lifespan could increased by up to 65 percent.. (8)
  9. They have done studies with a low-calorie diet on different animals such as rats, yeast, worms, flies, spiders, fish and several types of rodents, and have seen the lifespan of the animals increase from 25 to 65 percent.(6-7)
  10. The people who live the longest come from Okinawa, Japan. Their diet consists of a higher percentage of fresh vegetables than in most places, and fish and soy make up virtually all the protein. Okinawans consume 40 percent fewer calories than Americans and 17 percent fewer calories than the average Japanese.  (9)
  11. There have been studies that have demonstrated the effect of larger portions on consumption. Did you know that the standard serving portion size for almost everything is larger than it was a generation ago? We sometimes see this in restaurants, especially in the USA, were the servings are huge. The problem with huge serving sizes is that we eat more than we are supposed to. They did a experiment on people, where people were invited to a lab for a ¨taste test¨of soup. Some of  the participants got a bowl that had a tube connected to the bottom of the bowl, so that it was always full. The other participants ate from a normal bowl. All the participants thought they had a ¨normal¨ bowl. Those with the ¨bottomless¨ bowl ate 40 percent more!!


Certain foods are addictive, we have a hereditary predisposition for storing fat and we don´t have a strong instinct to engage in physical activity. On top of that we have changed drastically the way we eat, especially the last 80 years. Remember, and I know I have stated this a couple of times but it´s quite important, the last 10,000 years only represent 1% of the human evolution. Before agriculture we were hunter-gatherers and ate hundreds of plants and animals. The animals we ate were animals that were in the wild and had a high content of protein. The animals we eat now, are in farms, fed ¨shit¨ food, and given hormones to grow as fat and as quick as possible.  Another problem is that we eat much more than what we are supposed to. Just bear in mind that the people who live the longest on the planet are the Okinawans and they eat quite less than the average American or Japanese. Also, let´s not forget that the bigger the serving the more we eat (compare the dishes you have now with the ones your grandparents have).

So, with all this said, I think I found a solution to the problem. Instead of moving more, eating well and drinking better……… just buy smaller dishes !!! 😉

My next blog will finally be about sports. It will talk abou the myth of high repetitions. I think we have all heard that if you want to lose weight and tonify you have to do more repetitions, but is this true??  We will see in my next blog…. until then .

Is food addictive part 2?

In our last post we talked about how certain foods can be addictive by producing chemical changes in our brain. We also saw that eating refined fatty meals makes us stop producing Leptin. Leptin is a hormone which signals the body to stop eating, but we also saw that the reverse can also happen. Meaning that if you stop eating the junk food and start eating healthy, the levels of those hormones return to normal, so there is hope. But what is eating healthy?

10,000 years ago, which may sound like a long time but it equals to only 1 percent of human history, most humans lived like hunter-gatherers. Back then we used to eat a lot of meat (this meat, contrary to what we eat now, contained much more protein), fish, fruits, leaves and seeds. We ate more than one hundred species of plant- most rich in vitamins, fiber and other nutrients. Fats and sugar were rare but we developed a craving for them because they contain lots of calories, which was important back then to survive. Thanks to our diet, and because we were always on the move, people were lean but whoever could store fat had an advantage. So we developed a predisposition for carrying fat on our bodies as well as wanting it in our foods. The problem is, back then it was difficult to get too much of these foods, now it´s the complete opposite. So not only do we get ¨addicted¨ to these foods when we eat them, we also have hereditary predisposition for wanting to eat them.

So I guess I´m not saying anything new about what is healthy eating. I think most people know what is healthy and what is un-healthy, the problem is people don´t do it. And now we know some reasons why that is. It´s the same thing with physical activity, most people know they have to move more but they don´t do it. They always use excuses like they don´t have enough time or that something hurts, ironically most of these problems are improved by exercise. Biologically we need exercise, but we don´t have strong instincts to engage in it. Before, physical activity used to occur automatically while trying to catch or find out food, now it´s not like that. Back then no one would just go for a run, that would be wasting precious energy and calories, you needed all the energy and calories you could have. Those extra calories could make the difference between life and death.

This blog just gets worse and worse, not only do we have a hereditary predisposition for wanting to eat foods with lots of calories, but once we eat them we get addicted to them – and to top that off I just said that we don´t have strong instincts to engage in sports!!! No wonder we are loosing against obesity and getting fatter and fatter every day. But there is hope, I have seen it, even done it!! You can fight back …… I won´t tell you what you have to do because I want to keep the secret to myself but I´ll give you a hint: It has to do with eating and moving.

In my next blog, we will continue with the third part of ¨is food addictive¨ by mentioning some interesting facts that most people don´t know. Until next time I leave you with the second part of ¨The men who made us fat¨

Does eating late make you gain weight?
