Quoting N & Em's Mama:" I hope so! Lol I walk a mile each way to my train station and back 3 days a week, so that'd be great if it."
I am in your boat
I walk from Union to work and back 5 days a week.
But yes walking is enough but you need to WALK. Don't have to power walk but you can't walk mediocre slow.
Also make sure you eat well. Doesn't have to be 100% tofurkey-banana-protein-I.only.eat.celery kind of thing but just monitor calorie input.
Weight loss is 80% diet. 20% exercise.
