Question
“Pounds Off” Helps People Lose Weight
Do you need to lose a few pounds? Are you struggling to lose weight quickly?
Well, if so, this may not be true for much longer. New research has shown that you may be just a few months away from having the trimmer figure that you’ve always wanted.
So, you may be wondering, what is this new pill? It’s called “Pounds Off,” and it was scientifically tested for its effectiveness by a group of independent researchers.
Thirty people were randomly selected to participate in a study about the side effects of a medication. They were all told that the study would last for 3 months and that they would have to have a full physical at the beginning and end of the 3 months. Their weight was recorded each time by a doctor who was unaware of the purpose of the study.
Participants had to take a pill every day during the 3-month period. Immediately after they took the pill, they had to call or email the researcher to let him know; however, 13 out of the original 30 participants failed to do this. Those participants were dropped from the study because the researchers claimed that the effectiveness of the pills could not be tested if they were only taken sometimes or not at all.
The researchers for “Pounds Off” found that, at the time of the second physical, the participants who completed the study had lost an average of 25 pounds. At the end of the study, one participant, Megan Smith, said, “I tried ‘Pounds Off’ and it really worked for me! It seems like I tried every diet pill on the market before this, and nothing worked, but this time I actually lost weight. ‘Pounds Off’ is definitely one diet pill that works!” It should be noted that the results of this study were successfully replicated with another group of participants.
So, if you are ready to shed some weight, “Pounds Off” may be the right pill for you because it has clearly been shown to help healthy adults lose a significant amount of weight. What have you got to lose by giving it a try (besides a few pounds, of course)?
