Two young women of the same age and working in the same office, share a lunch meal together daily. While one very cautiously skips the carbohydrates the other one merrily gobbles up most of the meal. There is a remarkable difference in their weight. The one who is a conscious eater is overweight for height whereas the girl who enjoys her meal most is lean and slender. What makes their measurements different? Genetics, metabolism, hormonal or is it a lifestyle?
In this article, we will understand whether being obese is linked to inherited genes. Researchers claim there are 32 genes in human beings responsible for obesity (Nature Genetics, 2009).
Your genes may be responsible for your fat:
Many of these genes are thought to be related to the development of obesity through the deregulation of leptin or other metabolic hormones in the body.
Pediatrics experts study the obesity-linked FTO gene in children. FTO gene is located on the chromosome 16 and is expressed in the brain. As per the scientists, those who are at-risk of gene presence have been found to be up to 3 kg heavier than those who do not have the gene expression.
It is noteworthy to understand that this weight gain is likely due to the gene’s involvement in the regulation of energy intake.
According to research studies, individuals carrying the at-risk gene expression prefer:
- Energy-dense food
- Have reduced feelings of satiety
- Display overeating
- Consume more fat calories
- Display a greater tendency towards consuming palatable foods after eating a meal.
Thus, FTO gene seems to predispose individuals to greater caloric intake and reduced feelings of satiety.
On the other hand, experts also state that the gene FTO has no correlation to energy expenditure. As recorded by meta-analysis of 45 adults who were physically active, they could alleviate the odds of obesity associated with FTO gene by almost 30%. Thus carrying a gene expression for obesity does not necessarily preordain one to become obese.
What can you do?
With correct lifestyle measurements, dietary modifications and physical activity, calorie intake can be controlled and obesity may be prevented.
