I weigh around 320 and obviously i need to exercise and eat better, so i added more fruits and veggies to my diet and basicly cut out fried food. And im starting to exercise my question is if i walked for between 15-30mins a day at a steady pace with my dog how much weight could i potentaly lose since i do really no exercise (started walking this week). my goal is to get back down into the 200s.
