I've currently got quite a predicament and I was wondering if anyone can help me. I'm a 18 year old, 5 foot 9 male and I weigh 73-74 kgs. I have a slow to regular metabolism and find that I can weight quite easily if I'm sedentary. I have been injured for the past 8-10 weeks with a torn sartorius muscle and haven't been able to run or do any exercise. I wasn't that lean to begin with (not like I was when I was doing cross country) but I've gained a noticeable amount of weight and wish to lose it and get lean. I can currently only do light jogging every 2ND day and I'm not sure how much longer I'm going to be injured for (I have an appointment with a sports doctor in two weeks). I want to lose 10-12 lbs by September and I'm wondering if that is achievable with such a low amount of exercise, and if it is how should I achieve it in terms of calories and nutrition. Any help would be greatly appreciated.
