Ok those are very impressive accomplishments.

Exercise is the fountain of youth. I would take one gram of creatine a day two grams if you want a more alert cognitive function.

I would do a 16/8 fast three days of the first week. 12 noon lunch to dinner then done at 8pm. No clories no snacks. Black coffee is fine. No creamer or sugar. Monk fruit is great.

I did this and it helped me lose weight fast. Im down to around 224 but I do muscle training too and I am 6'1".

I hike, bike some and sometimes a sport or two. In my 20's I was heavy into sports so I can relate.

Once you get lighter you will surprise yourself at what you can do.

But some of your acheivements I could never do.
