I have recently started speed walking every day, I LOVE it. I feel wonderful since I have been walking. I weigh 337 (I have lost 10 pounds so far) I walk for about 30 to 45 min daily, but I feel like I could do more. I want to start walking 2 hours a day, what is the recommended time to speed walk per day for maximum results? any other tips? I also have an eating problem, If something tastes good (comfort food) I will often not be able to resist a second or third helping. I love to eat healthy, salads, fish, fruits, veggies, but often the opportunity presents itself for some good old fashion southern comfort food which I can not turn down. I LOVE southern cooking. I live in Texas so its everywhere. I am set on loosing at least 200 pounds. any tips? Thank you!
