According to researchers, in developing countries with a rise of 10 degrees C, there was a rise of 4% in the BMI of children and a 2% rise in BMI in women. It stated that BMI tends to increase at both low and high temperatures as there was a U-shaped relation between temperature and BMI.

Impact of temperature on obesity is a long-term outcome, which also makes people to stay indoors and which in turn, leads to reduced physical inactivity.

According to a 2019 Lancet commission report, climate change impacts plants’ protein and micronutrient content too, as elevated carbon dioxide levels have shown to reduce concentration in wheat, rice, potato, etc., by 10-15%.

When people spend less time in cool temperatures, the body’s need for adaptive thermogenesis reduces, leading to less demand for energy, ultimately leading to obesity.

According to the American Heart Association review of studies from 28 countries, today’s children are 15% less physically fit than their parents at the same age.
