It is more socially acceptable to lose weight because of illness than it is to gain weight because of illness.

Poverty too.

Poverty and obesity go hand in hand in this country, because fresh food and exercise are often a luxury, but when I lost 30 pounds because I couldn’t afford food or repairs on my car, people congratulated me, even though I kept getting sick and was tired all the time, not to mention the damage I was doing to my feet.
