Reasons Why Obese People Eat More Food
Obese people tend to be pigeonholed a lot by various studies etc, that basically say the reason they end up the way they do is because, of the amount of food they eat this is all true to a certain extent. But just recently some new research has shed some light on one of the reasons why this may be. From what has been found from the study is that obese people’s brains react differently, than those of thin people their brains tend to be more sluggish.
When it comes to their brain receiving the full signal and hence they stop eating. Apparently obese people have to eat more food in order to feel satisfied, so this is one of the reasons why obese people probably eat more food and struggle to lose weight, a study was conducted around some young women and girls and they were given what was called highly palatable food namely a “chocolate milkshake”.
They found that in obese people the neuro-transmitter chemical dopamine, is far less active in a obese person so hence they tend to eat more until they get the satisfied feeling. It was found that it was more so pronounced in women who were born with a gene, that makes a reduction in their dopamine production by at least 30 to 40 percent, their brains showed a real numbing effect as far as dopamine production was concerned. And were found to gain weight within a one period time frame.
What the researchers say about this study is that they may be able to, make drugs that turn on the dopamine response more and in the future this will stop people from gaining weight. They focused their research on a part of the brain called the dorsal stratum which is a reward part of the brain as regards food, it’s a part of the brain that features heavily in anything that makes us feel good it’s all the same neural pathways that are used.
Whether it be eating a nice meal, having a drink of alcohol, spending some money on something you really like, this is all part of the same neural pathway that gives us the same reward feeling. The reason they used chocolate for their particular research is because is one of the singlest most craved foods.
The first part of the study involved 43 females between 18 and 22 years of age and the second was 33 girls in the age group 14 to 18, they were scanned whilst drinking the chocolate or a non-chocolate drink, using aMRI (magnetic resonance imaging) scanner, to see what particular effects were found from drinking the chocolate.
This is when they found the breakthrough when they compared results there it was, when scanning a obese person who had drunk the milkshake, there was a blunting of the brain compared to those whom were thinner.And those people who had the blunting effect were far more likely to gain weight over a longer period of time.
What what they managed to gain from this is if you eat a diet which is high in fat and sugar, then your reward receptors in your brain gradually stop working as they would do, if you were a drug addict, or alcoholic you have to consume more of the particular drug. Or whatever it is that gives you the reward because after a period of time it no longer works the amount of dopamine that your back brain produces becomes a lot less. So in the case of food you have to eat far more of it to get the reward signal feeling and this is why obese people eat more food.
So this is why it’s important to not eat those particular foods that are high in sugar and fat, because then your reward mechanism will stay as it should do and is far less likely to become faulty and make you over eat. One of the researchers says that if you are eating fast-food every day of the week, then if you cut that out it would probably take about one to two months before you would notice any difference in cravings. Although this research was conducted mainly on women the people who conducted it said that it would probably the same for men.
This must be one of the most groundbreaking studies that have been done as far as obesity is concerned, and really thinking about it it does make sense, if you’re not getting a rewarding feeling from the food that you eat then it’s obvious that you’re going to eat more of them. This probably has a link with comfort eating because in order to get that reward feeling then you do have to eat more chocolate or sweet type, foods in order to feel satisfied hence the reason you get addicted to them and gain excess weight.
