I just thought of this soda ban. If you just cause fat people to stand up, walk to a soda machine, and then go sit back down, that's a lot of calories burnt right there. Lets say our fat person raises 100 kg of body weight .5 meters to get up to go to the soda machine.
F=100kg * 9.8 m/s^2
W=980N * .5m
W=490 Joules = .117 food calories
It takes roughly the same amount to stand up as sitting down, so double that, and also the efficiency of the human body is about 20% so...
(.117*2)/.2=1.17 food calories
With obesity at 70% and 8,244,000 population in New York, .7*8,244,000*1.17, that's 6.75 Million additional food calories burnt per day refilling soda.
