I was pretty badly overweight up until the summer after 7th grade (i'm a sophomore now), then i cut out soda and fast food for soccer. I lost like 15 pounds that summer, got in the best shape i'd ever been in, and felt all around great. I went a little over a year without soda, but one day i had an orange Fanta and couldn't drink the damn thing. It tasted like pure sugar, it was so bad. I started drinking soda again a little while after that, and i haven't really let myself go, but i definitely don't feel good. But anyway, me and my friend are going for a month without meat. We started yesterday and i'm not gonna drink any soda either during that time and see how healthy i feel on january first. Best of luck to anyone else who's cutting soda out of their life, it's not really that hard, just don't drink one and tell yourself it's only one, and it's nota big deal. You'll start breaking all of your unhealthy decisions down like that.
