Hi, I am new here and I am trying to lose weight by riding my bike... I am 15 years old and i weigh 235 pounds, I am 6'0 tall, and i am trying to get down into the 170-180 range. I used to bike all the time but now I've lost all my endurance and can barely ride at all. I would just like to know what would be a good diet, and how far i should bike per day, and maybe how to get my endurance back up so i can ride more than 2 miles without being out of breath, haha. It is kind of hard to bike around here because i live in pennsylvania and there are a TON of really steep hills where I live. When i sued to bike i biked around 12 miles per day or so. So... i just want to know what kind of diet i should be doing, how far i should be biking, and maybe some excercises to help me ride up hills easier or get leg strength or something, and maybe how long it would take me to lose these 65-75 pounds...
