The current plan (1) 1500-1800 cal/day (2) walk at least 2 miles/day (3) weight training 3 times /week (4) consider some sort of flexibility training. No particular high protein plans, although low simple sugars is the basic idea.
Is it physically possible for me to do? Hell yes. How long can I keep with it? No idea.
I am going to stick with this plan until I've lost 20 lbs, though. Enough is enough.
