I just started working out again over the last month after a layoff of about 10 years. When I was a regular at the gym back then I weighed about 190-200 and I maintained a body fat percentage of 5-7%, I think the weight lifting and constant cardio really helped to keep me lean. Anyway fast forward to 10 years in the future, I've put on about 80 pounds and who knows what my body fat percentage is I'm too chicken to find out. At any rate I determined that I would do what it takes to get back in shape and I've started lifting weights and doing cardio again. My goal is to get down to about 200-220 within the next 3-4 months.
So my questions are how can I find out how many calories a 280 pound guy burns off just doing everyday activities?
How do I determine how many calories I need to take in to maintain the muscle I have but still burn off fat?
How many calories will a pound of muscle burn off?
For the people who use HIIT (high intensity interval training) is it more effective than long sessions of moderate cardio for burning off fat?
Finally where can I go to find recipe and meal ideas (along with their calorie content)?
Thanks for any advice you can offer. hopefully in a few months I can post a few pictures of a new and improved me
