If you had used the 500 product before, and you enjoyed the taste, I would recommend that you use that product again. The difference between the 500 and the 800 is that the 800 product has more calories. There are 160 calories per serving, where the 500 has 100 calories. So you could save yourself some calories by using the 500. The 800 also has a richer taste because there are more calories. We do not recommend using the shakes as a sole source of nutrition if you are not on the HMR program at a clinic and are not medcially supervised by their Medical Director. But the shakes are still a great meal/snack replacement. They taste great and can cut your calories for the day. If you want to use 3-5 per day and add fruits and vegetables, that should help you to your weight loss goal. |
