Depends on your body type and metabolism and your routine. But usually it takes around 3 to 4 weeks for visible results. For me it took me a couple of months to actually see any progress visually.
I was wondering how long it would take to start seeing results? I have been working out in the gym 6 days a week for 90-120 minutes I started out at 175lbs and I am currently still 175lbs. I have been eating right 6 small meals a day 3 snacks (fruit & vegtables) and then sensible breafast lunch and dinners, and I still have not lost any weight.
