1. The types of food people eat, the quantities and frequency. While ice cream, restaurants, and snacks existed for several decades, people ate their much less frequently and the food was better. Soda came in 6 oz servings made of sugar and not HFCS, ice cream was a rare treat, and people ate more balanced foods. Doesn't mean you should sue any company, because it's entirely at fault of the individual.
2. Lifestyle -- not exercising or eating so many bad foods that running a little bit just creates a status quo.
Genetics is a rare case. Like a hypothyroid. Where were all the obese people 100 years ago? They certainly weren't half of the population. If anything, genetics is in actuality the eating habits and lifestyles taught to children by their parents.
There's some other minor factors, like sleeping, inbalanced intestinal flora due to killing all bacteria on food, etc, but it mostly comes down to 1 and 2.
Genetics are hardly rare cases (think Samoans), hypothyroidism is quite common, obese people have been around since humanity moved past the hunter-gatherer stage (including 100 years ago), and about a third (not half) of the population is considered obese today (BMI>30).
Hypothyroidism affects nearly 2 percent of the population, but is much more commonly found among certain groups

2% of the population is quite rare, especially considering there are treatments for it.
We're a melting pot, yet have higher obesity rates than our relatives. Nope, couldn't be that we're spamming children with fast food and junk food ads. Couldn't be that we're out in traffic every lunch break to get fatty yum yums because packing a healthy lunch isn't any fun. Couldn't be that we inject corn syrup from bread to yogurt. These things have bene around since the dawn of man. It must be genetic! lol

If it's so commonly genetic, then why weren't there many obese people in the past?
http://en.wikipedia.org/wiki/ObesityThis is most notable in the United States. In the years from just after the Second World War until 1960 the average person's weight increased, but few were obese. In the two and a half decades since 1980 the growth in the rate of obesity has accelerated markedly and is increasingly becoming a public health concern.
There are a number of theories as to the cause of this change since 1980. Most believe it is a combination of various factors.
