Weight Maintenance with Herbalife: Losing weight using Herbalife Products is Delicious and Easy but it is not necessary to replace 2 meals after you lose the weight. To maintain the ‘new you’, replace 1 meal a day with a Herbalife shake. Once you lose the weight you will most likely not need additional Protein as well. Don’t forget to take Herbalife Enhancers, or as our customers say, “the pills” if you need them.
