How Does Genetic Impact Weight Loss?

According to the experts, our Genetic determines our nose shape, hair color, eye color, etc., so it also makes sense that genes can play an essential role regarding our weight. This means some portion of our ability to eventually lose weight is encoded right in our DNA. And this is why every individual reacts differently when it comes to workouts and diets.

Science claim that our genetics may play a significant role in obesity. To learn more about this research you can visit here:

This means they can cause obesity in some disorders like Prader-Willi syndrome and Braden-Biedl syndrome. However, the genes are not 100 percent that they must predict someone’s future health and weight.

Behavior and Genes might both be required for any individual to get overweight. However, multiple genes sometimes tend to increase someone’s susceptibility for increased weight or decreased weight loss. Below is a guide that will help understand how Genetics can affect weight loss.


Genes affect our weight by their impact on:

  • Basal metabolic rateThis determines the much energy someone can burn when resting. Therefore, for people with low BMR, the experts claim that they are at risk of gaining more weight. Besides, our BMR may change in response to specific conditions.For example very low–calorie or starvation diet tends to decrease our BMR. This is because we tend to lose muscle and fat, you can read more here In this case, the muscle increases resting metabolic rate, meaning losing excess muscle will reduce your metabolism. On the other hand, severe physical stress and fever, such as recovery right from extensive burns or surgery, can increase someone’s metabolism.
  • Body signalsFullness, hunger, and appetite are among the body signals which tell us the much we eat. Besides, these specific signals can also be influenced by the environment or even ignored for short duration periods.
  • SetPointThe theory claim that our body tries keeping our weight within a particular range known as a set point. In essence, this range tends to be influenced by someone’s genetic makeup. So your set point can get adjusted to a fresh level when maintained for some time. And on the other side, it can get altered through overeating, some medicines, exercise, and some brain conditions.
  • How calories are utilizedSome individuals use calories competently – they require fewer calories to eventually fuel their bodies, resulting in having leftover calories stored as fat. On the other side, some individuals utilize calories lee competently- they require more calories for fueling their bodies, meaning they will have few leftovers calories to be stored as excess fat.
  • SatietyThis is that feeling of satisfaction and fullness. The stretch receptors right our stomach tend to send signals to your brain, telling your stomach is full. Therefore, increased blood sugar and the presence of food in our intestines subsidize satiety.


To what level genes can be blamed for weight loss?

Generally, the figure for overweight Americans is increasing day after another. Many studies claim that for you to succeed in the weight–loss journey, someone should take an approach that accounts for his genes as well as lifestyle factors.


The genes are linked to weight loss/gain.

Regardless that numerous genes are connected to different aspects of obesity, there are some genes that fully influence your weight gain or loss. These genes may affect appetite levels, energy use, typically burn calories, and body composition. Below are genes identified for weight loss:

  • MC4RThis gene is entirely known as a contributor to any human metabolism. It is responsible for controlling how your energy is used, from all that you eat to how you feel hunger. Besides, some individuals have rare variants to this specific gene which may cause overweight.
  • IRX3This is genetic, which might cause it challenging to weight loss. However, the researchers found that people with this gene-deficient showed 30 percent weight loss.
  • FTO GENEThis gene is associated with obesity and fat mass. It is found on chromosome 18. Besides, the presence of this specific gene is claimed to have a connection to overweight individuals.
  • ANKYRIN-BThis gene is known to cause the fat cells to absorb excess glucose at a very high rate. And this increases the size of these cells leading to weight gain.


How can someone stay in shape regardless of genetics?

Our metabolism is a powerful chemical engine that keeps us alive. The speed at which it runs depends on every individual. This means if you have a slow metabolism, you have increased leftover calories which are stored as fat. Again those with a very fat metabolism tend to burn additional calories meaning they are less likely to amass a lot of fat.


What are signs that genetics is impacting your weight gain?

Genes might have a potent influence on someone’s weight, especially for overweight individuals. This means if you are a parent or blood relative who is overweight, then there is a good chance your weight is due to a genetic issue. Generally, genetic predisposition increases the risk of being obese and overweight, but your lifestyle can also overcome this.

Whether you are among the individuals struggling with extended weight–term excess weight issues or soon started struggling with weight gain, it would help if you know if excess weight is because of the lifestyle of DNA. This might offer insights and clues to your situation.

Final Verdict

The genetic impact of weight gain or loss is not viewed as the final destination or lifetime obesity sentence. The good news from experts is that we can control these genes to a certain extent regarding weight loss. In addition, dietary modification, exercise, and lifestyle will help you maintain a good weight regardless of genetic issues.
