Has anybody heard of the 90 day challenge? It incorporates a nutritional shake mix as a meal replacement. Helps curb hunger ad assist in healthy weight loss. I have been doing it for about 3 weeks now and I feel great. I usually mix my shake with fruits, yogurt, ice, flax, etc. It's very versatile. Lactose free and diabetic friendly. If anyone is interested in learning more, please let me know.
