Right now I'm o/l vegetarian & overweight by about 70lbs. I want to change a lot (how I exercise, how I eat, etc) so I can be healthy in a holistic way, but I'm not one of those people who can do anything cold-turkey. So I came up with my phased approach, where I add something to my program and get really comfortable with it before trying to add something new. So far I just started Phase II.
Phase I: Walk 1.4 miles around my "block" daily. That's it.
Phase II: Walk + weight watchers
Phase III: Weight watchers, walking, weight train 3x week
Phase IV: Add 30 minutes of yoga 3x week (basically alternating weight training and yoga every other day)
Phase V: Step up from walking to jogging (a little at a time)
Phase VI: Remove egg yolks and any non-nonfat dairy from diet
Phase VII: Remove simple carbs (as much as possible) & artificial sweeteners from diet (i.e. white sugar, white flour, white rice, etc.)
Phase VIII: Remove eggs and dairy entirely from diet.
Phase IX: Increase to 4-7 fruits & vegetables per day
Phase X: Meditate 15 minutes / day
I figure I may stall on a phase, but at least I will be constantly progressing. And I won't be overwhelmed with feeling like there's too much that I need to change at once.
