Diet Pills

My friend is trying to loose weight, she just ordered this product off the internet called Diet.com. She knows a lady who is very overweight but after using the product has lost 14 pounds the first month, and tons of inches. My friends goal is to loose her weight before summer. The girl described the product as a pure protein and that it curbs your appetite for sweets. She actually said that her doctor recommended the product as a last chance before getting surgery to help with weight lose. My feelings are mixed. I wonder if it messes with the body and metabolism? You know how you hear about people gaining more weight after they diet, is this another one of those gimmicks? The other side of the coin is because my friend is so over weight she is stressing her body and her heart, so maybe this is better. I would love to know more about this product and how it works on the body's system. Exercise and eating healthy are so important and I think working at it daily will help implement good habits.
