A number of studies, including the Danish adoption study, have shown that, in adults, the familial resemblance of obesity, as measured by the body mass index (weight in kg/(height in m)2), is mainly due to genes. The body mass index may reflect both fat and fat-free body mass.
Why is obesity hereditary?
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. Changes in MC4R that diminish its function are found in a small fraction (<5%) of obese people in various ethnic groups.
Can obesity run in the family?
Your family history can increase your risk of obesity because the disease does run in families, according to the American Academy of Family Physicians (AAFP). However, your genes aren’t the most worrisome risk of obesity. Your upbringing can be a much bigger problem.
