Is obesity an effect of global warming?

How environment plays a role in obesity?
Some of the environmental conditions that lead to obesity are physical activity, alcohol consumption, socioeconomic status, parent feeding behavior, and diet. Interestingly, some of these environmental conditions are shared with neurodegenerative and neurodevelopmental diseases.
Did the food environment cause the obesity epidemic?
Disentangling the relative contributions of these environmental variables is a difficult problem, but it seems clear that the food environment is likely the primary driver of the obesity epidemic.
Why is obesity an environmental issue?
Obesity is an environmental issue. Societies that are transitioning to westernized lifestyles are experiencing substantial increases in its prevalence. The primary environmental determinants of obesity are high calorie intake and low levels of activity.
What are the environmental factors that cause obesity?
What are the biological causes of obesity?
Many factors influence body weight-genes, though the effect is small, and heredity is not destiny; prenatal and early life influences; poor diets; too much television watching; too little physical activity and sleep; and our food and physical activity environment.
What is global obesity?
Adult obesity is more common globally than under-nutrition. According to the World Health Organisation (2016), there are around 2 billion adults overweight, of those 650 million are considered to be affected by obesity (BMI ≥30 kg/m²).

Is obesity a global crisis?
Worldwide obesity has nearly doubled since 1980, there are more overweight adults than underweight ones, and it is now recognized as one of the most important public health problems facing the world today (World Health Organisation, 2013).
