That is pretty close to what I used to drink in sodas every day. I was never without a soda nearby. I weighed over 215 pounds, which is pretty bad for my body frame, I'm 5'9". I stopped drinking sodas and essentially replaced them with sugar sweetened tea and my weight dropped to 195 lbs. I have since cut out the tea, replaced with plain water, and my weight is now around 188 and has been stable for a couple of years. I don't exercise and my job is basically sedentary for most of the day. The HFCS consumption now is only a small fraction of what it was. I know this is not scientific, but it works for me........
It is interesting to note that in countries like Japan, England and Mexico, where they do not use HFCS in any significant quantity, obesity has become a serious problem.
