Healthy habits to lower genetic obesity risk

Obesity is a complex and multifactorial condition that affects millions of people worldwide. Behavioral and environmental factors such as diet and physical activity have been shown to play a significant role in obesity development. Still, the role of genetic factors has also been found to be significant.

Indeed, genetic variations can influence many aspects of metabolism, including energy expenditure, appetite regulation, and fat storage. However, people who inherit a gene that makes them more likely to be obese are not destined to be overweight. Genes merely provide a blueprint for potential outcomes, but various environmental factors influence their expression, including diet, physical activity, sleep and stress.

So, we’ll discuss some healthy habits that can help combat genetic obesity risk.

Genetic Basis of Obesity

A complex interplay between multiple genetic, epigenetic, and environmental factors regulates the human body weight. Researchers have identified several genes involved in appetite regulation, energy expenditure, and metabolism contributing to obesity development. Some of the most well-studied genes associated with obesity include:

1. FTO Gene: The FTO (Fat Mass and Obesity-Associated) gene is one of the most well-known genetic contributors to obesity. The variation in this gene is associated with a higher body mass index (BMI), increased fat mass, and an increased risk of obesity-related diseases, including diabetes and heart disease.
2. MC4R Gene: The MC4R (Melanocortin-4 Receptor) gene is crucial in regulating appetite and energy expenditure. It has been found that mutations in this gene increase BMI, increase food intake, and decrease energy expenditure.
3. PPARG Gene: The PPARG (Peroxisome Proliferator-Activated Receptor Gamma) gene regulates fat cell differentiation and lipid metabolism. The variation of this gene is associated with a higher risk of obesity and insulin resistance.

Other genes, such as POMC, play a role in appetite regulation, while others, such as LEPR and INSIG2, affect lipid metabolism and insulin sensitivity.

Even though the genetics of obesity is becoming increasingly understood, there is still a lot to learn. Researchers are still attempting to determine the exact mechanism by which these genes affect metabolism and energy balance. 

Some studies suggest that there may be a connection between these genes and the levels of certain hormones, such as Ghrelin and Leptin, that are involved in the regulation of appetite. Others suggest that these genes may affect the activity of specific brain regions that control food intake and energy expenditure.

In addition to identifying genes that play a role in obesity, researchers have also begun investigating ways to turn off or on these genes to prevent or treat this condition.

Environmental Factors and Gene Expression

In addition to genetic factors, environmental factors such as diet, physical activity, and lifestyle also influence gene expression and, ultimately, the development of obesity. For example, a high-fat diet can increase the expression of genes involved in fat storage, while physical activity can increase the expression of genes involved in energy expenditure.

Furthermore, epigenetic modifications can influence gene expression and contribute to obesity, for example, DNA methylation and histone modifications. Epigenetic modifications are affected by environmental factors such as diet and lifestyle, offering potential targets for obesity prevention and treatment. Therefore, a healthy lifestyle allows you to take control of your health and turn off these genes. 

How to turn off obesity genes through a healthy lifestyle

Here are some scientifically-proven ways to turn off obesity genes with a healthy lifestyle:

• Eat a healthy and balanced diet

One of the most effective ways to turn off obesity genes is to eat a healthy and balanced diet. 

Several nutrients, including folate, vitamin B12, and choline, have been shown to influence DNA methylation, which in turn influences the expression of genes related to energy metabolism and obesity.

According to one study, a diet containing high fiber and low fat can improve DNA methylation patterns and decrease the expression of inflammation and obesity genes.

Researchers have also found that a Mediterranean diet, with plenty of fruit, vegetables, whole grains, and lean protein, can lower obesity risks and improve overall health.

Therefore, you should eat foods full of nutrients, such as vegetables, fruits, whole grains, lean proteins, and healthy fats. Avoid highly processed and sugary foods, which contribute to weight gain and obesity-related diseases.

• Exercise regularly

Exercise is another crucial component of a healthy lifestyle that has also been shown to influence DNA methylation and gene expression. If you engage in regular physical activity for at least half an hour daily, you can lose weight, reduce body fat, and improve your metabolic health. 

Several studies have shown that moderate exercise reduces obesity risk significantly. Adults should exercise at least 150 minutes a week at a moderate intensity.

• Get enough sleep

Getting enough quality sleep is essential to maintaining a healthy weight and turning off obesity genes. Several studies have shown that lack of sleep disrupts hormones that regulate appetite and metabolism, causing weight gain. Ideally, you should sleep 7-8 hours a night.

• Maintain Portion Control:

It is also important to control portion sizes when trying to lose weight. Smaller portion size can help you lose weight by reducing your overall calorie intake. Studies have shown that people who use smaller plates and bowls tend to eat less, and this is a useful way to control portion size.

• Manage Stress

Stress can also trigger obesity genes and contribute to weight gain. You can reduce stress levels and improve your overall well-being by practicing stress-management techniques such as meditation, yoga, or deep breathing exercises, which reduce stress levels and boost your mood.

• Avoid smoking and excessive alcohol consumption

Smoking and excessive alcohol consumption can also activate obesity genes and lead to weight gain. Quitting smoking and alcohol consumption decreases the risk of obesity-related diseases and improves overall health.

• Maintain a healthy weight

The key to turning off obesity genes is maintaining a healthy weight. The loss of even 5-10% of body weight can improve metabolic health and reduce the risk of obesity-related diseases. Focus on sustainable lifestyle changes that promote a healthy weight rather than quick-fix diets.

Medications and Obesity

While lifestyle changes such as a healthy diet and regular exercise are the cornerstone of obesity management, there are also medications that can help in the process. There has been growing interest in medications that can help turn obesity genes off in recent years.

A number of appetite suppression medications based on GLP-1 have demonstrated promise in this area. GLP-1 (glucagon-like peptide-1) is a hormone that the body naturally produces in response to food consumption. It triggers insulin secretion and suppresses appetite, making it an attractive obesity treatment target.

GLP-1 Appetite Suppression Medications

Medications that mimic GLP-1’s effects are known as GLP-1 agonists. Currently, these medications are approve to treat type 2 diabetes but have also been studied for their potential in managing obesity. In addition to increasing insulin secretion, these medications can reduce appetite, which can lead to weight loss.

A number of studies have shown that GLP-1 agonists can be effective in helping to turn off obesity genes. One study, for instance, found that treatment with GLP-1 agonist liraglutide led to a significant decrease in DNA expression of obesity-associated genes in overweight and obese adults.

In another study, GLP-1 agonists were examine to see if they influenced genetic predisposition to obesity. The authors concluded that these medications have the potential to reduce the risk of obesity in individuals with a genetic predisposition to the condition.

While GLP-1 agonists show promise as a tool for turning off obesity genes, it is important to note that they are not a magic bullet. Lifestyle changes like a healthy diet and regular exercise remain the backbone of its management. However, GLP-1 agonists may be a valuable addition to their treatment plan for individuals struggling to manage their weight despite these efforts.

Gene Editing and Obesity

The development of gene editing techniques such as CRISPR/Cas9 has opened up new possibilities for the treatment of genetic disorders such as obesity. As a result of gene editing, it may be possible to correct or modify genetic mutations associated with obesity, thereby reducing the risk of obesity-related diseases.

However, gene editing raises ethical concerns and requires a careful assessment of its benefits and risks. In order to fully understand how gene editing will affect human health. And the environment in the long run, further research is necessary.

Genetic Testing

Genes can affect how your body regulates energy, making you gain weight and lose it slowly. A genetic test can provide valuable insights into how your genes impact your ability to regulate your weight and appetite. For example, 21 genes influence how you maintain a healthy weight, and four genes influence how you feel hungry and full.

However, not all obesity genes have a significant impact on your weight. Some genes are protective and can help you fight disease more effectively. In fact, the genetic impact is sort out as follows:

• Protective
• No impact
• Low impact
• Medium impact
• High impact
• Very high impact

Therefore, it is important to understand how a gene affects the body. For example, if 19 of 25 weight and appetite regulation genes are protective, have no impact, or have low impact, then only six genes can affect weight and appetite. Still, these six genes would interact with others with greater impact, such as those related to inflammation, glucose, and insulin.

Managing your weight is challenging when inflammation, glucose, and insulin levels are high. If your genetic roadmap shows inflammation, glucose, and insulin regulation have the greatest impact, lowering these factors may be more effective than following a restrictive diet and exercising more.

Therefore, a genetic test can be a valuable tool to understand how your genes impact your weight and health. If you know your genetic blueprint, maintaining a healthy weight will be easier.

Conclusion

Although genetics plays a role in the development of obesity, it is not a predetermined fate. Environmental and behavioral factors can influence gene expression and modify the risk of developing obesity. We may be able to prevent and it can be treat by understanding the genetics of obesity and how gene expression can be modify. A healthy lifestyle can reduce obesity risk and related health complications for individuals. A small change in lifestyle can have a significant impact on overall health and well-being. So prevention is always better than cure.
