62: Ghrelin Ghrelin is one of the most important hormones, participating in the nutrition and metabolism processes (1). Ghrelin is responsible for creating sense of hunger and for "deciding" how much and which energy should be used. Ghrelin is produced in an empty stomach, when it enters the brain, ghrelin connects to the same receptors as leptin (this is a satiety hormone). That means you cannot be hungry and full at the same time. Ghrelin regulates, whether the calories (nutrients) from food will be used for production of energy (ATP), heat, glycogen ("fast" energy) or fat. As the weight increases, level of ghrelin in the blood decreases, and this causes hunger to be felt less frequently. If level pf ghrelin in the blood is increased artificially, hunger is not bigger, but more frequent. Therefore it is considered that ghrelin is the weight control measure. Ghrelin plays part in feeling pleasure when eating tasty food or alcohol (2). When eating for pleasure (not for hunger), level of ghrelin and endocannabinoids in the blood increases (7). Besides other functions, endocannabinoids are responsible for pleasure when eating sweet foods (6). Higher level of ghrelin is related to antidepressant effect. On the other hand, higher level of ghrelin in this research was achieved by increasing level of stress. We know that increased stress has a number of negative consequences (3). Anyway, it looks like when facing stress, depression in difficult to experience. If body lacks sleep, level of ghrelin increases, level of leptin - decreases (4). But you cannot compensate sleep with food, even if you are driven to. In a stress situation level of ghrelin increases regardless of the level of adrenaline produced (5). This is why people feel hungry when stressed. What else can be said. Sleep well, take care of your inner peace, resilience to stress - and eat only when you are hungry. 1. https://en.wikipedia.org/wiki/Ghrelin 2. https://en.wikipedia.org/wiki/Ghrelin#Function_and_mechanism_of_action 3. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2765052/ 4. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC535701/ 5. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3988273/ 6. https://en.wikipedia.org/wiki/Endocannabinoid_system#Functions_of_the_endocannabinoid_system 7. https://academic.oup.com/jcem/article-lookup/doi/10.1210/jc.2011-3018

Another book that I would like to recommend. Not the only one of this kind, I will come back to this later as well. Even though it is not psychology, but this knowledge is still very important. One of the obstacles that does not allow to achieve the desired result is lack of knowledge about how things work. If you stand in front of the door with the key in your hand, but have no clue how to use it - you can spend loads of time just standing there, experiencing despair, anger, blaming the door, the key, yourself or the others. But the door will not open because of this. Accepting this fact, also that knowledge needs to be verified, collected, updated - is the field of psychology. This specific knowledge - on food and eating - currently is developing very rapidly. There are still things that are valid, but a lot of other things that are new, and even contradict the previous "truths" - to avoid fats, to snack, to eat until full and not get hungry by any means, to eat sugars or food in general in order to have energy (whatever that is), to be able to compensate by exercising if you ate more the day before, to be able to "burn" excess food, etc. Now we know more, so we can treat our bodies a lot better and achieve results a lot faster. Bon read. #spoonfulofreading #books #psychology #nutrition

Research. People tend to eat more when they feel more positive emotions as well as they feel more negative emotions than usual (here we should think of both celebrations and stress situations). On top of that, people tend to eat more after they overeat (here we should think about feelings of guilt and helplessness). I short, emotional peaks are a risk for overeating. My take on this: it does not really matter whether you "let yourself go" during vacations, or you "seek comfort" in food when stressed - too much food is too much food, with all the consequences. Emotional problems need to be resolved using emotional tools (like deliberation, planning, behavior rehearsal, speaking), and food needs to be used food-related issues (obtaining nutritional substances). Your dismay or frustration does not have a role in the physiological digestion process.

73: Barriers to the healthy nutrition As I am back to the city, I am also back in the flow of messages encouraging me to "let yourself go", "to treat myself", "to go for the sweet sin"... Without too much effort it is easy to see that healthy eating is seen as trouble while almost-non-food items that are also lots-of-pleasure products are shown as a guaranteed benefit. Almost like cocaine, but it is not popular to be advertised and definitely not legal to be distributed. How have we come to this - things that are good are difficult, and not a pleasure? I have looked at some qualitative research hoping to find what are the reasons as told by the people themselves. Men in United Kingdom say they avoid to choose healthy food because they have a cynical attitude towards government's messages on healthy eating, besides, healthy food does not taste well and is not satisfying. Authors believe this is related to the need of men to be independent and strong (which may mean they do not agree with government and to avoid deprivation (1) Australian children and their parents state that the primary barrier to the healthy nutrition is contradicting messages sent to the children - what advertising says and what parents say are two different things, you need to void fats, and fats are necessary, salt is both harmful and beneficial, TV has both useful and harmful shows (2) Adolescents in Ireland say that they do not choose healthy food, because they do not get the expected physical and psychological reward when eating healthy food, (mis)understanding of what is food and what is healthy eating, contradicting social pressures regarding food, and basic misunderstanding of what healthy nutrition is. Interestingly enough, healthy eating concept is masked behind pressure to eat unhealthy food and pressure to be thinner (3) UK adolescents say that they do not choose healthy food because of poor food quality in the school, also very accessible, relatively cheap and personally more tasty fast food. Supporting factors are family support, accessible healthy food, wish to care about the body image and a power of will (4) Speaking about the healthy elementary school children nutrition, their parents say that among barriers they see food provided in school, opinion of the peers (some foods are not "cool"), poor example shown by brothers and sisters, also parents and grandparents that are not living together. Parents did not see their own example as important. Parents believe that children have unchangeable tastes which shape the diet of their children. Finally, parents believe (researchers say - incorrectly) that healthy food must be prepared at home, fresh, organic, and because of all that - hardly accessible (5) Older British men say that they do not follow healthy diet because they lack skills to cook and they lack wish to change their life habits (6) There are many more research papers. But conclusion for me is quite sad. We are used to cook and eat in certain way, and unhealthy one, we have a habit of thinking that we must get the food quickly, and that time spent on cooking is time wasted (even if we are learning to cook healthy food - this is still considered the waste). We simply ignore any long term healthy eating consequences and keep luring ourselves with an instant pleasure, even if we will blame ourselves afterwards, daily. What is your reason to "treat yourself" with unhealthy food? ----------------------------------------------------------------------- 1.
