Although researchers concluded that genetics plays an important role in a person’s weight, they stressed that it isn’t the sole factor.
Race or ethnicity
Just like genetics, some racial and ethnic minority groups lean toward extreme weight measurements.
According to a longitudinal study published in 2016, the Philippines is among the top 10 countries in the world that have the largest number of underweight men and women. Data showed that the number of underweight men and women nearly doubled from 1975. The country had 3.6 million underweight men and 4.4 million underweight women. The study, however, did not take into account socio-economic factors that may have led to such statistics.
Diet and environment
Diet and environment play a significant role in weight. Many people can’t afford or lack access to nutritious food. Some do not eat properly because of an illness, stress, or lack of sleep. The lifestyle and eating habits of family and friends may also contribute to these food choices.
If you undergo high-level physical activity then you will burn a lot of calories. If you accompany this with a poor diet, you may find yourself losing too much weight.
Illnesses and disorders
Certain diseases like hyperthyroidism or diabetes and disorders like anorexia may affect your weight. In particular, hyperthyroidism speeds up your body’s metabolism rate causing rapid weight loss. If you suddenly start losing pounds despite eating a lot, it’s better to consult your doctor on how to gain weight safely.
