Theres not much wrong with that. You don't have to cut out all of your chocolate if you don't want to, just that ones at 20:00 and 15:30 really. Replace your 15:30 one deffo with a flapjack or another peice of fruit though. Saying that. If you replaced your 12:30 bar with a flapjack you probably wouldn't need a choccy bar at 15:30 anyway.
Thats the reason I don't buy GOLD bars anymore! I open them up and just eat the whole pack!
