All my family members have the health problems you listed, it was what inspired me to start eating primal. I was about 20 pounds overweight and I knew if I continued on that trajectory I'd end up the same way as my siblings.
It's great that you are starting eating this way at your age, I think I would have had much better overall health if I'd started at your age. I didn't find primal until I was a good 20 years older than you!
If you haven't already done it I recommend making a big batch of bone broth and having it throughout the day.
We like to flavor ours with a generous amount of sea salt and lemon or lime.
Congratulations on taking charge of your health!
