Are you planning on losing 40 pounds in 12 weeks? That seems like a very unrealistic goal and the only way you could do this is to starve yourself and exercise all day, every day. Plan on losing one to two pounds every week  and eating around 1400-1600 calories a day. Also plan  on exercising for at least 30 minutes every day. That way you might be able to lose 20 pounds. Maybe.

One pound is equal to 3500 calories.

Simply and mathematically speaking, you would need to have roughly negative 1500 calories between diet and exercise each day to acomplish this. 

So, if you need 1800 calories each day to live - reduce it to 1300 calories from food (-500) and burn 1000 in exercise (approximately 1.5 hours of jogging on a treadmill) for example.

It's tough and a lot of hard work and dedication, but it can be done. Just rememberto plan an exit strategy so you don't go back to your previous bad habits.
