I was a fit active teen, then had 3 kids and was at my current weight, joined weight watchers and lost all the weight and was again a physically fit active mother at 150 with only 12% body fat. Then i started having alot of dietary issues (IBS) and i gained all the weight back again. Tried going Gluten & Dairy free and it worked lost all the weight but still had the stomach issues. Found out it was all caused by cutting out sugar (aspartame and sucralose) and it was also in my new generic daily ADHD medication . I removed all sources of these chemicals from my diet, i havent even chewed a peice of gum in over a year. I also took a year off from taking the mediction (something ive needed to take since middle school) to be sure the chemicals were truly the cause, and all the IBS issues and symptoms i had been experiencing went away. Again at my heaviest weight i am back on the medication but specifically made by a manufacturer that doesnt use those chemicals. And now im also going back gluten free and am going to attempt to get my active healthy freedom back once again.
