Patti, it's great that you are discovering what works for YOU.
From my personal experience, it's better to make changes one at a time, like testing for food allergies. No more than once a month. Things can get blurred when more than a change is done in a short period, which may confuse the results and lead to wrong conclusions.
In addition, combine your changes with your charts, this will help draw parallels. For instance, one can try a supplemet and lose weight, thinking that was the reason that broke their stall. But looking at the chart, one can see that a stall occures every x amount of weeks, and then a sudden drop, nothing to do with that supplement.
Or, it happens that at the same time, a friend went on vacation and gave you their dog to look after
It is a known fact, brisk walks are great for weight loss, and dogs force you to walk. Funny starange things like that can be captured by careful charting of your progress, daily intak and exercise, measurements and methodical experimentation.
By the way, this is a general comment on experimentation to share with others, you have more experience in this than myself
