It's not easy for some people, but we have so many more obese people than most other countries (including developed and undeveloped countries). Why is that? I have been around 6-0 150 my entire life which is probably average in many countries, but I have been told I'm too skinny and need to put some meat on my bones on many occasions. I eat plenty, never go hungry and am generally healthy, so I never feel a need to gain weight. For some men though, there seems to be a pressure to be big. At social events, people (both men and women) are compelled to eat a lot. It feels like the same pressure put on people to drink alcohol. Maybe that is something that needs to change about our society.
