Obesity rates by state:
And google search indices for "weight loss" by the same:
The correlation between the two is a rigorous .77 (p = .00*), a remarkably strong relationship for such a measurement, and at the state level to boot.

Advice gleaned from a longitudinal study with a sample size of one: Cut the carbs, especially sugars and anything wheat-based, then eat to satiation without counting calories, points, or gil.

Have sex three or four times a week (really, moderation is golden here).
