OK, I am new to biking. I got my bike last fall, but have only seriously started riding for about the last 3 weeks. I ride for at least an hour, which is about 9.5 miles. (week 1 it was only about 7 miles, so I'm improving).
I want to lose weight, and feel better. So, I've gone from 256 lbs to 261 in the last 3 weeks. I have NO idea what I'm doing as far as nutrition goes for biking. I do feel my clothes are a bit loser, and that muscle weighs more than fat, and so when you gain muscle, you tend to go up, so I'm not devastated over the small gain. However, I would like for that to go DOWN with diligence. I would also like to increase speed to OVER 10 mph.

Advice would be greatly appreciated from everyone!

Thanks,
