I've been experimenting around with foods lately. My trainer and I were talking about calorie intake etc so I said I'd do a little test with my last four day. I took only soups. Each was 200 cal per serving or 400 cal per can. I kept my average calorie intake around 1600-2000 calories a day. I exercised heavily one of the days where I burned about 1000 calories. When I got back I had gained 4lbs Each can had 1030mg sodium which is almost a full daily intake! Water weight adds up quick lol. Hit the sauna today and got it all out. Won't be taking soups again.
