Hi folks, i am planning to replace my lunch with Lean-up Protein Shake Mix-french Vanilla, I have to do this because earlier I used to garner a lot of carbohydrates in my lunch and this started to create a big problem as I gained 10 lbs in no time. This was actually miserable for me because being a model I have to take proper care of my physique. My instructors suggested me to replace my one meal with this supplement in order to retain my original shape. Will this work, or there can be some kind of problem.
