I first learned of HerbaLife through my friend who was a major supporter of HerbaLife. He is a health instructor, and he convinced me to try a few shakes. I tried one, and it was delicious and I was surprised to find that it had enough nutrients to replace a meal! The program is great and the shakes are very filling. I was on the program for a few months, and the people working for HerbaLife helped me every step of the way. They checked up on me daily, gave me encouragement when I needed it, and made me proud of my accomplishments. There are many delicious flavors to satisfy whatever you're craving, and I personally love all the flavors they offer. If that isn't enough, they do have great snacks to choose from! My only complaint with HerbaLife is the price. If you are willing to pay a good price for a diet that works, I recommend HerbaLife. HerbaLife is MUCH better than SlimFast because the shakes really do fill you up. One shake was enough to fill up my stomach, and I have learned to pass up on the donuts in favor of a shake instead. The HerbaLife program, while expensive, gave me the boost of confidence I needed to keep my goal of losing weight and living a healthier life. Effectiveness HerbaLife works very well and does its best to cater your needs so that you get the nutrients you need for meal replacement while giving you many flavors to choose from! Side Effects As far as I know, there are no side effects. Ease of Use The shakes are very easy to make, but they can take a while. However, the shakes are delicious and fill you up!
