I want to do a lot of things for longevity, but a lot of them would be embarassing since I live with a bunch of people (I'm in the military). Yet, I notice the signs of aging on me more than ever before, and the main reason is because I gain 30 lbs since last year. In the military, we eat three times a day, and so I kind of just eat as everyone else does, and yet I have a slow metabolism. I don't feel fat, but I am reaching that threshold. I gain a lot of muscle as well.
I want to eat bare minimum, excercise in front of people, and just do whatever it takes to get me to the results I want. The problem is I have a huge fear of people thinking of me as a weirdo, but I also know if I don't work on my goals I won't reach that status I want.
Any advice?
