I ride a bike 4 days a week for an hour and a half per and work out with weights and would be happy to tell you what works for me.
I lost weight over a year period. I am very close to being a vegetarian. No red meat fried foods. I eat lots of veggies chicken and fish. I have kept it off for over a year now. I do the treadmill 3 or 4 times a week walking jogging. 30 minutes at a time. Then I do a little weight lifting.
