Healthy Eating


Healthy Eating Fundamentals

Let's face it. Eating healthy is tough. And in this Land of Opportunity, there is no greater opportunity than the opportunity to eat unhealthy food. But with a little effort and a dose of education, a healthy diet can be yours.

How Much Should I Eat?

To know how much you should eat, it's important to understand calories. Calories are a meaure of energy, and generally used as a measure of how much energy is in food. On nutrition labels, the number of calories in a serving of food shows how much enengy is in that food. This is important because your body needs a certain amount of energy (i.e. calories) every day. So another way of thinking about how much to eat is to ask the question: how many calories should I eat?

Sources of Calories

Calories come from fat, protein, and carbohydrates:

  • 1g Fat: 9 calories
  • 1g Protein: 4 calories
  • 1g Carbs: 4 calories

How Many Calories Should I Eat?

Good question. You've probably seen nutrition labels that say the average diet is 2000 calories per day. That's true. But very few people are perfectly average. The amount of calories you need each day depends. It depends on your age, height, sex, level of exercise, speed of your metabolism, and many other factors. Below is a calorie chart to help you determine generally how many calories you should eat each day. If you would like a customized daily caloric intake level and have a few minutes, check out Dr. Larsen's Healthy Body Calculator.

Daily Calorie Requirements:

Sendentary (Less than 30 minutes on most days) 2200-2400 1600-2000

Super Active (More than 60 minutes on most days) 2600-3200 2200-2400


Amount of Calories in Food

Most of the food we buy today is labeled with nutrition facts. However, if you find yourself eating and unable to check the package--because, for example, you are eating out, there are still ways to find out nutrition facts.

What Should I Eat? The Pyramid

Pyramid Shortcomings:

But the new pyramid has some shortcomings, including lumping refined sugars together with complex carbohydrates and recommending drinking three glasses of milk a day, which can give millions of lactose intolerant Americans stomach problems. For these reasons, we recommend using the Harvard School of Public Health Healthy Eating Pyramid. Take a minute to look through the pyramid. It provides a good first answer to the question, what should I eat.

Why Should I Eat These Foods?
