Healthy Food Pyramid

The Healthy Eating Pyramid sits on a foundation of daily exercise and weight control. Why? These two related elements strongly influence your chances of staying healthy. They also affect what you eat and how your food affects you.

Exercise and weight control are also linked through the simple rule of energy balance: Weight change = calories in – calories out. If you burn as many calories as you take in each day, there's nothing left over for storage in fat cells, and weight remains the same. Eat more than you burn, though, and you end up adding fat and pounds. Regular exercise can help you control your weight, and it is key part of any weight-loss effort.
