The problem wiht not eating before breakfast is you can not do high intensity workout, you say how not having breskfast will burn more fat, well then the brekfast will put the fat back in you.
You will not mange to do high intensity with out breakfast, trust me on that because real excersize means you need to eat proper food. When i cycle (must confess iv been a bit lazy recently) i had breakfast first and a bit of food during the ride, i had a carbohydrate drink aswell, once i had none left so took water instead and guess what, i passed out, and i was so weak it took me days to recover. You cant do real excersize, with out food yet this is the stuff that burns the cal's 500 per hour for 2 hours 30min = 1500 cals, no wonder people are worying about when to have breakfast in order to loose most weight when their work out probably burns less cals then is in their breakfast.
Personaly i dont care about cals, i just care about my fitness levle.
If you had enough decidation to excersize properly, and cut out sweets/ junk food, you could eat as much as you like and you will stay thin.
