Can you really control your health? New research shows the power of lifestyle habits

Have you ever used to make the excuse, "I'm not genetically healthy..."? I used to think the same way. However, the latest research from 2025 has produced some interesting results that overturn this assumption. Based on the article "Are You In Control Of Your Health? Science Says Yes — Here's Why" by mindbodygreen, we discovered that lifestyle habits have a greater impact on health than DNA (deoxyribonucleic acid: the molecule that carries genetic information). In this article, we'll explain the scientific evidence in an easy-to-understand way, even for beginners. Let's explore why lifestyle can surpass genetics in a story-like way.

Let's start with a story about a researcher. Imagine two twin brothers. One is an exercise-loving, plant-based brother, while the other is desk-bound and eats nothing but junk food. They share the same genes, so why is there a difference in their health? A large-scale study published in 2025 scientifically explained this. A team from Oxford Population Health compared the effects of environmental factors and genes and found that in many cases, lifestyle habits have more than twice the impact of genes on health and lifespan. An article in mindbodygreen summarizes this as "environment and lifestyle have a major impact on aging and disease."

The key point of this research is that genes do not determine one's destiny. For example, the risk of heart disease and diabetes (a disease in which blood sugar levels become abnormally high) is more strongly related to lifestyle factors such as smoking and lack of exercise than to genes. Related research reported in TIME magazine on February 25, 2025, also emphasizes that lifestyle habits are the main factor in determining lifespan. When I gather this kind of information while writing my blog, I realize just how important the choices I make are.

Research Details: The Science Behind Lifestyle Overcoming Genes

Let's take a look at some specific research. The mindbodygreen article (published October 4, 2025) is based on recent scientific papers, which point out that the influence of environment and lifestyle outweighs the influence of genes when it comes to aging and disease. For example, an Oxford study reported in Science Daily on February 20, 2025, showed that lifestyle factors such as smoking and physical activity have a greater impact on health and the risk of premature death than genes.

This study utilized big data to analyze data from tens of thousands of people. The results showed that, depending on the disease, lifestyle factors outweigh the influence of genes in over 60% of cases. A Harvard Health article (May 1, 2025) also stated that lifestyle has a stronger influence than genes in the cases of atherosclerosis (a disease that hardens the arteries) and rheumatoid arthritis (an inflammatory joint disease). On the other hand, while genes play a large role in certain diseases such as dementia (a disease that impairs memory and judgment) and macular degeneration (an eye disease), these conditions can still be alleviated through lifestyle changes.

An interesting study published on YourWeather.co.uk on March 20, 2025, found that lifestyle choices have a greater impact on ageing than DNA, highlighting that environmental factors can accelerate or slow the ageing process. For example, regular exercise protects telomeres (the ends of chromosomes that are an indicator of ageing) and can help offset genetic risks.

Why does lifestyle matter more than DNA? Explaining the mechanism

Genes are like a blueprint, but lifestyle determines how that blueprint is executed. The field of epigenetics (a mechanism that controls gene expression and influences it without changing the DNA sequence) is key. A study published in PMC on June 12, 2022, found that lifestyle affects DNA methylation (a chemical change that regulates gene expression) independently of obesity (excessive body fat accumulation). In other words, diet and stress turn genes on and off.

An article by mindbodygreen summarises these mechanisms in a positive way, saying, "You can control your health." For example, an April 29, 2024, article by CNN reported that a healthy lifestyle can reduce genetic risk by 62%. Quitting smoking and increasing exercise can significantly reduce the risk of premature death, even if you have bad genes.

A little bit about my experience: Since I started blogging, I've made daily walks a habit, and my mental health has improved. Science has shown that physical activity increases endorphins (happiness hormones) and reduces genetic predisposition to depression. These kinds of changes are easy for anyone to make.

Lifestyle habits to adopt in real life: practical advice

So how can you improve your life? Here's a list of practical, research-based tips. For beginners, we'll start with the simple ones.

Get into the habit of exercising: 150 minutes of moderate exercise per week (walking or jogging). An Oxford study found that this reduced the risk of heart disease more than genetically determined.
A balanced diet: Eat lots of vegetables and fruits. A 2025 article in TIME points out that this diet is a key factor in increasing lifespan.
Quit smoking: Smoking is the biggest lifestyle risk, and according to Harvard Health, quitting smoking can significantly offset your genetic risk.
Stress management: Meditation and yoga. Epigenetic research has shown that stress causes changes to DNA, so try 10 minutes of relaxation every day.
Ensure you get enough sleep: 7-9 hours of quality sleep. Lack of sleep accelerates aging, so make it a routine.

Just by trying these things, you should be able to feel a sense of control over your health. For example, I have heard from readers that "improving my diet helped me lose weight and reduce my worries about genetic diabetes." Of course, results will vary from person to person, so start with small changes.

Caution: Don't ignore the role of genes

While lifestyle is important, it doesn't mean you can completely ignore your genes. An April 3, 2024, article in WebMD emphasizes the interplay between genes and lifestyle. For example, genes strongly influence some types of cancer, so don't forget to get regular checkups.

Also, mindbodygreen itself is a wellness brand, and 2025 reviews (Medical News Today and Life Coach Magazine) have praised it for providing high-quality supplements and coaching. However, the articles are general information, so please consult a medical professional for advice.

Summary: Your choices change the future

Ultimately, your health depends more on your lifestyle than your genes. And as a 2025 study shows, there's a lot you can control. Start making small changes today to create the lifestyle you want.
