Around 35-40 per cent of a child’s BMI — how fat or thin they are — is inherited from their parents, a new study has found. For the most obese children, the proportion rises to 55-60 per cent, suggesting that more than half of their tendency towards obesity is determined by genetics and family environment.
Can obesity be genetically inherited?
One gene or many? Rarely, obesity occurs in families according to a clear inheritance pattern caused by changes in a single gene. The most commonly implicated gene is MC4R, which encodes the melanocortin 4 receptor.
Does obesity pass on?
A person’s risk of obesity is heavily influenced by the genes they inherit and the environment they live in. The combination of factors leads to childhood BMI rising in line with parental weight, surveys have found.
Does obesity run in families?
The results confirm the results of our previous analysis of body mass index. We conclude that human obesity is under genetic control, whereas the childhood family environment has little, if any, influence on obesity in adults. It is an important task for future research to identify the genes involved.
Can obesity be cured?
Experts: Obesity Is Biologically ‘Stamped In,’ Diet and Exercise Won’t Cure It. New research into the biological mechanisms of obesity suggests eating less and exercising more aren’t enough for people with long-term weight problems.
How common is genetic obesity?
However, recent studies suggest that genetics contribute to 40-70% of obesity with the discovery of more than 50 genes that are strongly associated with obesity.
Why obesity is not genetic?
Rarely, a clear pattern of inherited obesity within a family is caused by a specific variant of a single gene (monogenic obesity). Most obesity, however, probably results from complex interactions among multiple genes and environmental factors that remain poorly understood (multifactorial obesity).
Is obesity environmental or genetic?
Obesity is simply defined as having too much body fat for your particular weight or height. An average figure from the relevant research estimates that obesity is about 40% genetic and 60% due to environmental factors.
Is it better to be fat or thin?
If you are skinny but carrying too much weight around your middle than it can put your health at risk.
How do I know if I am overweight?
Adult Body Mass Index (BMI)
- If your BMI is less than 18.5, it falls within the underweight range.
- If your BMI is 18.5 to <25, it falls within the normal.
- If your BMI is 25.0 to <30, it falls within the overweight range.
- If your BMI is 30.0 or higher, it falls within the obese range.
Why do I never lose weight?
There are some medical conditions that can drive weight gain and make it much harder to lose weight. These include hypothyroidism, polycystic ovarian syndrome (PCOS) and sleep apnea. Certain medications can also make weight loss harder, or even cause weight gain.

Can you be obese healthy?
So the answer to the question is essentially yes, people with obesity can still be healthy. However, what this study, and prior research, shows us is that obesity even on its own carries a certain cardiovascular risk even in metabolically healthy individuals.
