I did it once and I lost about 25kg in 3 months. Soon I realised I had reset my metabolism. I gained weight fast even by adding little more calories. And soon later, am back to previous weight.

I would say eat right and workout

Eating 500 calories chicken breast and work out will make u thinner. But eating 500 calories of junk and workout will not help you any way.

erm, if you're burning more than 500 cals working out you'll still lose weight

Cardio is boring.
Perform this exercise called 'Complex'
Surely meltdown your Fats
