That's what my "age corrected" BMI came to also 22.1. But on there even my "real" BMI is in the healthy range. I had posted before that on an app I put on my phone to calculate your ideal weight it said a man's ideal weight stays the same through out his life but a woman's changes as she gets older.
I really don't want to go below 125 as my mom is a very tiny woman and has become very frail in her late 80s. So it is best to have a bit of heft to you I think. Of course it will take me to my late 80s to get to 125 so being too small will never become a problem.
Linden with the research on nutrition or on anything really the problem is that it is all done on the "normal" range of people. So if there is something "different" about a person, such as being super carb sensitive then you don't fit the norm and need to study carefully how any change you make changes your condition.
For instance I weigh myself every morning which most people consider a taboo on this plan. But if I hadn't done that for the past ten years and watched what effect certain foods had on me I'd still weight 200+.

Also, the sleep tracker was great. And about the foods -- remember, your taste changes a lot as you progress so I'm hoping things will get better. I still swear by the puddings with 16 ounces of water made into a really creamy shake.
I also weigh every day. Wouldn't consider doing anything else. Data is data. Facts are facts. And they are just that. They don't carry any moralistic baggage. They just are. They just exist. But you sure can use them to do all kinds of interesting analyses.
