"i am a 32 year old nurse and mom of 5. before i started taking fastin,  i was 269 pounds.  i&#039;m only 5foot 4 inches so needless to say i was huge. i was in size 24 jeans. i began taking these as a last ditch effort to help me lose weight and feel better about myself.   this week i weighed in at 187. (i recommend only weighing once a week on the same day before you eat or drink anything).  i am now in a small size 16, which are big on me.  i will agree that it makes your heart feel like it is going to pound out of your chest,  but that is how i felt when i exercised. i would be huffing and puffing and barely able to stand.  so i feel that in order toactually burn off the fat,  you have to pump the blood harder and faster. works for the obese."
