Okay, I joined a gym a few weeks ago, and I started out cycling, and most recently I've started to jog 5mph on the treadmill. I'm about 200 pounds right now, and I want to lose at least 40 pounds. Problem is- about 2-4 minutes into the jog, I get this weird stingy pain in my rib around right lung or around there. Will this go away in time or do I need to talk to my doctor?
Also, I've calculated that I consume about 1200-ish calories a day. I don't know if I'm allowed to eat at night if I'm trying to lose weight though. I go home from school at 4, then eat a small meal and go to the gym and head back home at 7. I get kinda hungry at by then but I heard alot of people say not to eat after 6. My mom also isn't home until 8ish at night so there's no dinner till 9. Is it bad if I eat during this time or should I just starve it off?
