You have to eat right like 3 times, eat vegetable too. a day and exercise every day that way you can develop ur muscles and then u will have energy

Eat breakfast. Just think about it, say you eat dinner at about 7 pm. So you go to bed, wake up the next morning, skip breakfast and eat again at about 12 well that means you haven't ate anything for almost 16 hours. We all need food and without it, our body's don't function right, we become cranky and just cant think straight.
Exercises! I can't stress this enough, If you want more energy you have to exercises! just a simple run or jog around the block everyday can have a dramatic effect on your energy, it's weird you'd think you'd have less but after you catch your breath again you feel great and want to go get chores done and things like that. I'm a really slow runner but that doesn't mean it dosen't give me more energy it's whats right for your body not anyone elses. and if people make fun of you for running, make fun at them for not because you'll feel better have more energy get in shape have a better attitude and this person probably is tired all the time, and upset all the time.
And last get your recommend hours of sleep. If you improve these 3 things they will help you ten times better then any energy supplement will and they don't cost a thing!

Here's a good breathing exercise that will quickly give you a lot of energy
