I cut Pepsi out of my diet for a short period this summer. (a couple months) Walked after work everyday with my sister.. ended up dropping 20 lbs. Then, in June, I was diagnosed with CLL and the diet thing didn't seem too important anymore. So, when I eventually got my appetite back, I ended up going back to drinking soda and all the other garbage I loved when I was heavier, in an effort to gain a little weight back. (I was 275 lbs. about 18 months ago, dropped to 200 lbs.. now weigh approx. 210 lbs.)
I plan to go back to my water only diet, and start to lift weights as soon as my doctors give me the go ahead. Got alot of loose skin I plan to fill with muscle, this time around.
