When we are overweight, our friends and doctors always say that it is because we eat too much and move too little. Obesity being our own fault kind of becomes a cliché. But is it always true?
A new study recently found that an individual with obesity just gets more satisfaction from food!
Different taste makes you eat more
The new study in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, found that participants with obesity had greater taste perceptions than those who were not obese.
Researchers at the University of Iowa conducted a non-clinical, randomized controlled trial of 290 adults between 18 to 75 years old (161 with normal BMI, 78 considered overweight, and 51 considered obese) to measure instantaneous taste perceptions. 80% were female.
In the trial, all participants were offered one piece of chocolate in a controlled environment and were allowed to eat as much as they wanted without feeling uncomfortable.
The study identified a consistent association between taste from chocolate and BMI by observing instantaneous taste changes over a period of time instead of observing the beginning and end of a period of consumption as in prior studies.
It turned out that the appeal of a specific food may decline as more of that food is eaten: the first bite of chocolate is way better than the 10th piece of chocolate.
As anticipated, researchers found that participants with obesity had higher levels of initial taste perception and rated subsequent pieces higher than their counterparts without obesity. Also, participants who were hungrier before the study had greater taste perception. And women's taste perceptions declined faster than men's.

Specifically, obese women needed to eat 12.5 pieces of chocolate to fall to the same level of taste perception as nonobese women, who only needed to eat 10 pieces. And this 2.5 pieces of chocolate corresponds to a difference of 67.5 calories, which may explain why obese people eat more than others.
In this case, if you have a different taste towards food, then obesity is not your fault as it is the thing one cannot control.
Causes of obesity
Have you ever thought that your community environment can have something to do with your overweight? It sounds a little bit unbelievable, but it is true.
All your community, your home, school and workplace settings may influence you and make you stay in your sofa or bed instead of go exercising. For example, you may choose not to go to work by walk or by bike just because there is no sidewalks or bike trails.
Another factor leading to obesity that you cannot control is gene, the mysterious gene.
Variants in several genes have been identified that they can increase hunger and food intake, thus contribute to obesity.
In some cases, obesity can result from complex interactions among multiple genes and environmental factors. Unfortunately, scientists don’t know how exactly this works yet.
Some diseases and drugs can cause obesity, these include Cushing's syndrome, Polycystic ovary syndrome, some corticosteroids, drugs for epilepsy and diabetes and drugs for antidepressants and schizophrenia.
Another thing most people don't know is stopping smoking can also contribute to weight gain.
A poor lifestyle
You don't become overweight in just 24 hours. Obesity needs time to develop as a result of your poor behavior.
Ask yourself these questions. Do you eat much more than you need, eat large amounts of processed or fast food, go to a restaurant a lot, love soft drinks and alcohol, and always rely on your cars instead of walking or cycling? Well, if answers are all "yes", you should really consider making some changes.
To keep a healthy diet, you should drink a lot of water and eat whole grains, fruits, vegetables, lean protein, low-fat and fat-free dairy products. As for physical activity, it is suggested that an adult should do at least 150 minutes of moderate intensity activity or 75 minutes of vigorous intensity activity, or a combination of both. A 2-day strength training per week is also needed.
