In my experience delving into health and nutrition, one consistent theme has surfaced time and time again is the interplay between genes and lifestyle. The ongoing debate about nature versus nurture, or in this context, genetics versus eating habits, is a conundrum that researchers worldwide have grappled with.
Research suggests that “copy number variations” or CNVs in our genes could partially explain why some people are more inclined towards obesity than others. These CNVs, according to studies, differ among ethnicities, indicating a genetic aspect to obesity.
However, envision a hypothetical scenario to understand how such studies could be interpreted. Picture two research groups. Group 1, comprising obese children, is supplied with a constant stream of fried chicken, sodas, and candies. Their concerned parents, anxious that their kids might go hungry, sneak in cookies.
Contrast this with Group 2, comprised of skinny children, who are given water during the study. Their parents, in the waiting room, offer them fresh fruit. By the end of one session, the obese children have gained an extra pound, while the skinny kids have maintained their weight.
Consider the case of Sammy, an obese child from Group 1. He’s born into a family with a history of obesity. However, Sammy’s after-school routine involves snacking on fried foods and sipping on sugary drinks. On the other hand, meet Jenny from Group 2, who, despite having a similar genetic predisposition towards obesity, maintains a slender frame. Jenny’s secret? Her parents ensure she’s stocked with fresh fruits and water instead of high-calorie snacks.
Another example is Thomas, also from Group 1, who despite a genetic inclination towards obesity, manages to control his weight by choosing healthier food alternatives and engaging in regular physical activity. Then there’s Sara from Group 2, a skinny child genetically, but with poor dietary habits. Over time, she finds herself in the clutches of obesity, demonstrating that our dietary choices can override even the ‘best’ genetic predispositions.
These anecdotes demonstrate that while genetics play a part in our predisposition towards obesity, it doesn’t determine our destiny. What we choose to consume, our dietary habits, the environment we create for ourselves and our children hold as much, if not more, sway over our health and weight.
Genes can load the gun, but lifestyle pulls the trigger. We need to stop laying all the blame at genetics’ door and take accountability for our choices. We are not passive recipients of our genetic heritage, but active shapers of our health destiny. So, make the choice today, for a healthier and better tomorrow.
