How does your overall diet look? What does a typical day look like?
Shakeology is a meal replacement, which it looks like you've been using for breakfast.. But it can also be used as a snack. It will only help you lose weight if you use it along with clean eating, like Emily said

Make sure you're eating at least 5 times a day and CLEAN! You'll for sure see results if you are keeping track and disciplined.
Also, I would give Shakeology the full 30 days before you make any decisions. Be consistent with it, drink it everyday, you should notice a few changes!
