It's not just calories you need to look at... Look at fat/saturated fat etc etc!
Eating before bed is a big no no either, as it basically turns into fat lol
In simple words, as they say - to lose weight you need to burn more calories than you intake...so replace you energy drinks (loads of sugar) with water, all snacks with healthy food (fruits).
Also, glass of water when you wake up - to wake up your digest system...and eat more often but less...that way you will keep your digest system and your body working all the time - which will digest food faster, without it going into fat and your body will burn more calories on its own.
Basically, less fat/sugar etc, more fruit and veg and more exercise lol
