Incorporate different kinds of exercise in your routine: When you work out don't just stick to one kind of workout. Incorporate strength training, cardiovascular training and stretching exercises into your routine to make it well rounded.
Learn proper portion size: To avoid eating too much of even the healthiest foods, keep track of how much you're eating. For most people, meat servings should be about the size of a deck of cards and other servings vary by the type of food.
Eat breakfast: Start your day off right with a good meal when you get up. Whether you're rolling out of bed at noon or up at the crack of dawn for a class, make sure you start your day with a balanced, healthy meal.
Drink water: Drinking enough water can help boost your concentration as well as keep you from overeating. Make sure to keep hydrated as you go through your day by bringing water with you.
