well you have PLENTY of time to lose weight before your wedding if that is your goal...so take that stress away...going to the gym is great and has many benefits, but if you really want to lose weight, the most important thing is your diet..70% of losing weight is diet, the other 30 is gym...so start with the diet...count your calories or do weight watchers..start with that and when you start dropping some pounds and feel good, then start working out
