Vegetarian and fat %

Hello, I'm trying the site again for the third or fourth time...I'm not particularly overweight but my body fat percentage is really high and I want to lose a stone. The fat content in my diet is too high (figures), so if there are any veggies out there that are sharing diaries I'd love some motivation please! I haven't been able to exercise since May either, due to damaging my knee and in desperate need of ways to get in shape without using my knees for the time being, so any ideas on that score, gratefully received.

Thanks :)
