On the whole I'm rather amazed at how many people on a fitness site have leftist views
Why? The fattest states in the US tend to have rightist voting patterns, while the least fat states in the US tend to have leftist voting patterns.
The states with the highest rates of obesity in the US are Mississippi, Alabama, Tennessee, Louisiana, West Virginia, Arkansas, South Carolina, Georgia, Oklahoma, Alaska, and Missouri. All except possibly Missouri are likely to vote rightist this presidential election.
The states (and DC) with the lowest rates of obesity are Colorado, Vermont, Connecticut, Rhode Island, Massachusetts, Hawaii, Utah, Montana, DC, California, and New Jersey. All except Utah and Montana are likely to vote leftist in this presidential election.
