if you want to lose weight and be in shape, and have energy, you need to find out what works best for you diet-wise and go for it. There is no one miracle diet that works for everyone, science and studies have proven this. You need to find YOUR diet.
Breakfast IS the most important meal of the day, followed by lunch. Skip that and you are toast, no pun intended.
But concerning energy drinks, those will suck the life out of you. If you want energy: eat a banana (natural sugar), coffee (stimulant w/out sugar).. natural stuff where your blood sugar won't spike up and downwards.
