I was very fortunate to meet Dorian Yates and Kai Greene at the Expo friday and had the chance to chat for a few minutes and they were happy to give me advice. My main question i asked them both was as i am looking to lose fat was what was their view on people saying a calories is a calorie and its all about calories in versus calories out. Both of them confirmed what i had thought in that its not that simple and that the body uses and reacts to different foods in different ways. I basically said how so many people (on here mainly) i read say its just a simple case of calories in and calories out and they both say thats total bull as carb cals will affect insulin levels promoting fat storage etc whereas fat/protein cals wont and will fill you up for longer and mean you wont get the insulin spike causing fat storage. SO........... If that has been confirmed by the likes of Yates and Greene why do so many still insist its a simple case of a calorie is a calorie??
