Any pills PROVEN to cause weight loss have been banned. They were all pretty much just different versions of amphetamines. Don't bother wasting money on any pills or miracle weight loss potions. Diet and exercise!
Cut out sugar in all forms - no junk food, no potatoes, no rice, no pasta, no bread, no fruit. Stick with meat, fish, eggs, and lettuce and try to exercise 30 minutes a day. Its tough - but I lost 150 lbs in 90 days!
don't use the pills!!!!! they aren't regulated by the FDA, and therefore may not list all the ingredients. some have strong prescription drugs in them in amounts so high they can kill you!! if you really want to lose weight, do it the healthy way. or maybe go find more information on sensa, I've heard good reviews on that, never tried it myself.
Sometimes pills do help but it's mostly you that has to do the work. Healthy eating and exercise does the trick. There used to be lots of products out there with effedra and are now banned by the FDA because of deaths they caused. Now a majority of companies replace the effedra with extra caffeine to replace it but it can also be harmful for you. Not long ago a teen lost her life drinking energy drinks that have way to much caffeine. Be careful what to look for. Go all natural an you'll see the pounds come off
