First - CONGRATS on finishing a month of Insanity! Especially with your crazy life style

Without changing your diet, you are still making changes to your body.
Fat vs MuscleSo even if you are not losing on the scale, your body is converting fat to muscle. You will see a difference in inches and also in your fitness level. That is why it is so important to do the fit tests, take pictures and measurements.
Now, if you want to get the most out of your program, you should start tracking your food and eating a cleaner diet.
Here is the link to the Insanity Diet:
Insanity Meal PlanThis is a simple, clear way to eat with the program. If you can stick to this, you will see greater results.
Let me know if you have any questions... I am on my second round of Insanity and trying to clean up my diet too

You can do this without Shakeology... you'll just need to plan a bit for healthier meals (thankfully it's a bit easier while traveling these days).
