Herbalife is not a sustainable healthy way to lose weight, no matter what they try to sell you on.
Here's what I suggest to get started on a really healthy way to lose weight.
First of all, read the sticky posts around the various forums. There's tons of good information on nutrition, weight loss, and exercise.
Next, sign up for a free account on either fitday.com or thedailyplate.com and start logging the food you eat. This is a huge step and a big eye opener for a lot of people. Just seeing how much you eat and how the calories and nutrients balance out is very helpful.
The biggest thing that has worked for me is to not just "go on a diet" but to realize that healthy eating and maintaining a healthy weight is a LIFESTYLE. I focus on clean eating - eating healthy, natural foods, in reasonable amounts.
Exercise is also key. You don't have to join a gym or kill yourself working out. If you're just getting started, something as simple as a nice brisk walk once a day is very effective. Adding in some simple things to your day - climbing stairs, moving more, all will help you to reach your goals.
Tell us a little more about yourself - what you normally eat, how much you exercise, what you like to do ... and we can help you with more specific advice.
