How many times should I work out to lose weight?

I'm 14 and I just want to lose 10 pounds or so, nothing major. How long should I work out and how many days a week? And also, what should I eat? I'm a vegetarian so meat/poultry/pork is out of the question, and I don't eat fish either.How many times should I work out to lose weight?
Three days a week of cardio (20-30 minutes) is fine. If you're ambitious, you can alternate strength training the other three days, which will build muscle and speed up your metabolism.How many times should I work out to lose weight?
Graze 5 to 6 times a day. Instead of sticking to just three meals a day, try grazing. Grazing means try having 5 or 6 smaller meals instead of three king sized meals. It is an excellent way of having smaller quantities of food.How many times should I work out to lose weight?
I'm 15 I worked out during the summer for 3 weeks and idk if I saw the difference lol. Go on the treadmill for an hour that's what I did. I think I did loose weigh. It's cause I didn't weigh myself before working out... So yeah lol
