Better analytics through PowerPivot

[nocheeseplease]

I have downloaded a year's worth data from my fitbit surge data, MFP and Withings scale.  I am using it in a PowerPivot cube to do better analysis than what we get from Fitbit.  Some of the areas I'm interested in:

How does lack of sleep impact my step count the following day?  Does a really bad night of sleep affect a couple days?

What does sharp increase in running mileage do to my weight and bodyfat %?  

Am I really making the most of my days off by exercising more?  

Does eating more protein result in weight gain, more/less sugar consumption and/or lower overall calories?

To anyone:  Can you think of other questions that I should ask that multiple data data elements could answer?

To others who use a multidimensional model to analyze your data:  What dimensions do you use besides date?

I track total calorie deficit and weight loss.

LOL, I recognize another stats person.  If I had a small amount of weight to lose, I would probably do the same things.  However, with more than 150 left to go, I would drive myself insane doing this kind of stuff.  Good luck though   🙂
