If you exercise the right amount, you will also feel happier and will have more energy.
Be a healthy eater. It's okay to splurge on your favorite foods once in a while, but it's important to maintain a healthy diet so your body can feel good on the inside as well as look great on the outside.
Eat three balanced meals a day. Many people skip meals because they think it'll help them lose weight, but this will actually make you cranky and tired.
Have a healthy serving of fruits and vegetables every day. Make sure to dip your hand into your fruit bowl a few times a day, and to eat your veggies with as many meals as possible.
Avoid foods that are overly-processed or fatty because they will make you feel tired and may hurt your digestive system.
Listen to your body. Part of having a beautiful body is not overdoing it when it comes to working out or eating right.
If you're feeling extra tired or thinking you're coming down with a cold, it's okay to skip the workout you had planned. You're better off taking a break than making yourself feel worse, which can prevent you from exercising for even longer.
If you're really craving an ice cream sundae, eat it. It's better for you than eating everything else in your fridge except the thing you really want. You should give in to your cravings--with moderation.
