Do different personality traits and preferences have any relationship to what type of food people need--based on what foods someone's body responds to in certain ways--such as gaining, losing, or stabilizing weight, energy, and mood?
Although weight tends to increase gradually as people age, the researchers, led by Angelina R. Sutin, PhD, found greater weight gain among impulsive people; those who enjoy taking risks; and those who are antagonistic – especially those who are cynical, competitive and aggressive.
What scientists may need to do in further research is to clearly identify the association between personality and obesity, as many doctors and fitness trainers know that different bodies respond in different ways to different foods. Some people metabolize carbohydrates and proteins one way, and other people respond to carbohydrates or proteins in another way, for example either by gaining or losing weight, managing and stabilizing the weight they maintain, or by other responses to food that may be metabolic, chemical, or genetic/cellular.
Do introverts and extroverts need different types of food?
"Previous research has found that impulsive individuals are prone to binge eating and alcohol consumption," Sutin explains in the news release. "These behavioral patterns may contribute to weight gain over time."
So actually, further research is what's needed for clarity about how different personalities respond to various foods and beyond personality preferences that may be inherited, how someone responds chemically and metabolically to various food and combinations of foods. An example is how does one person's body process carbohydrates, and gains weight, and how does that compare with someone who eats only carbohydrates and stays thin?
Another topic for further research might be: Why does one person have low cholesterol or large LDL particles while eating lots of meats and fats, but another person gets high cholesterol, high insulin or high blood sugar levels, and small LDL particles that may calcify the arteries from eating a high fats diet or lots of meats, but may respond to a vegan diet in a different way, depending on how a person's genes, metabolism, and body chemistry processes different foods. What research also needs to look into is how foods affect moods and how introverts and extrovert choose their foods and how the chosen foods affect introverts and extroverts differently.
Among their other findings: Conscientious participants tended to be leaner and weight did not contribute to changes in personality across adulthood
"The pathway from personality traits to weight gain is complex and probably includes physiological mechanisms, in addition to behavioral ones," Sutin explains in the news release. "We hope that by more clearly identifying the association between personality and obesity, more tailored treatments will be developed. For example, lifestyle and exercise interventions that are done in a group setting may be more effective for extroverts than for introverts."
