I agree with KJ (shocking, I know
don't try to make too many changes or make drastic changes. Several years ago, Reader's Digest had a Change One program. You make one small change, stick with it every day for 10 days or so, then add another change. You are slowly developing new habits.
since weight loss is more about what you eat than exercise, start with getting your nutrition under control. If you already enjoy exercise, don't stop! But if you need to work on BOTH, start with nutrition.
some good starts:
don't drink your calories
measure everything you eat
use the nutrition tracker
get 4-6 servings of fruits & veggies every day
chose baked or grilled over fried
make more of your own meals
eat for QUALITY
again, just tackle one thing at a time.
