My best friend and I agreed to be weight loss buddies...YAY! ...now what?

No matter how I variate my question on google, I get the same results..."Find a Weight Loss Buddy!" "Benefits of a Weight Loss Buddy!" "Try This Diet Plan!" "Use Our Mobile App Called Workout Buddy!"

But...okay, where are the suggestions on what to do with a weight loss buddy?

I have composition journals in hand with no clue what to do with them. Obviously, we have different weight loss goals and ideas on how to carry them out...so where do we begin to go through weight loss together and how do we formulate a plan to follow through with our goals?

If you have ideas or have better ways to google it...any suggestions are welcome!
