Eat a healthy diet.
The saying "you are what you eat" has truth to it! You should be eating a balanced diet that's filled with fruits and vegetables, lean meats like fish or chicken, and whole grains. Also, avoiding too much caffeine, sugar, and high-fat foods will help you to stay within a healthy weight and be more energized and alert. Your diet should also include lots of water, which helps keep you hydrated, your skin clear, and flushes out toxins.

Get down to a healthy weight.
The actual number of a healthy weight varies from person to person because of different body types, heights, and so forth. Because the number on the scale can fluctuate so much with water weight, it's not the best measure. Going by your BMI (body mass image) is a good indication if you are at a healthy weight or not. Your body fat percentage is also a good indicator. Being within your ideal weight range will improve your body inside and out-being overweight or obese puts your health at risk for heart problems, diabetes, and high cholesterol.

Exercise.
Getting plenty of exercise (experts recommend 30 minutes or so a day) is crucial for improving your body. Not only does it improve your circulation and heart, but it helps keep (or get!) you trim and energized throughout the day. If you dread the thought of exercise, try to incorporate it into your day in little bits, such as taking the stairs instead of the elevators, parking your car farther out so you can walk, taking walks on your lunch break, lifting free weights while you watch TV, and so forth.

Lift weights.
This doesn't mean you need to become a bodybuilder by any means, but lifting weights will improve your body in a number of ways. Muscle burns more fat, so the more muscle you have the more fat you will burn even when you're not working out. Your body will also look more toned and lean when you start to get definition in your arms and legs.

If you are a woman and are worried about bulking up, don't be. Women don't have enough testosterone in their bodies naturally to bulk up like a man. Start with light hand weights and work your way up to heavier weights if you want, but you don't need a ton of weight to make a difference in the way your body looks.

Get plenty of sleep.
Believe it or not, the amount of sleep you get can improve your body as well. Studies have shown that not getting enough sleep can increase levels of a hunger hormone within the body, which can lead to overeating. In addition, other ways sleep deprivation can negatively affect your body include higher chances of heart disease, hypertension, and slower reaction times. Try and get at least 7-8 hours of sleep a night to help improve your body.

Improving your body can be done in many ways and will come with a little effort. These are some of the best ways you can improve your body.
