A short while ago I wrote a review about the Instinct Diet. The research behind this diet is so meaningful because it supports what we already knew all too well. We eat more than we need because we CAN! We have evolved as human beings in a way that prompts us to eat when food is available. That’s normal! The problem is that food is available all too often and we no longer have a good concept of what is enough.
How has this come about? Having access to plenty of food is a blessing, something that was not experienced by most humans throughout history. Knowing what to do about the easy access to abundant food is another story. It has become harder to judge what is enough in part because the norm no longer matches our needs.
Portion sizes in restaurants and packaged foods have grown substantially over the years. What was once considered to be a large portion is now standard fare. Combine larger portions with the admonishment to clean our plates and we have a real problem. As a general rule Americans have learned to eat the food they are served. This is one way in which we limit what we eat by external cues. In many other cultures, people will more often limit what they eat based on internal cues of fullness and satisfaction. (To learn more about internal vs. external cues for eating as well as the dominant food culture in the United States read See it, Eat it with tips from Brian Wansink, PhD, author of Mindless Eating: Why We Eat More Than We Think )
Research by Marion Nestle, PhD (chair, Nutrition and Food Studies, NYU) has shown us that the trend toward bigger portions began in the 1970’s. I was a college student in the 70’s. I remember how a serving of french fries was a small amount, about 2-4 ounces totaling 210 calories. Now fries can be 6-7 ounces with a whopping 610 calories or so. Bagels were once about 3 inches in diameter and had about 140 calories. Now bagels can be 5-6 inches in size and have 350 calories or more! Beverages need an entire article of their own to cover the changes over the last 30-40 years. (You may want to read: The Beverages You Drink May be Making you Fat!)
Here’s what you can keep in mind to gain back some control over how much you eat. “Portions” refer to how much we are served by a restaurant or food packager or what we serve ourselves and it may have little to do with what we need. “Serving sizes” relate to the recommended amount of food a person needs based on sex, age, and activity level.
You can get a sense of how much you need by referring to the USDA Food Pyramid. (Be prepared to click on lots of links!) Or better yet, determine your caloric needs and then refer to the 1200 calorie diet plan or 1500 calorie diet plan I share on this site. You’ll get an idea of how many servings you need from each food group and how much constitutes a serving. (Read Calories Count to determine your caloric needs for weight loss or maintenance.)

You might also find it helpful to have a visual in your mind of the size of a serving. The National Heart, Lung, and Blood Institute has come up with some visual guidelines
to give you an easy to remember picture in your mind of the size of a serving for different foods.
What Does a Serving Look Like?
Vegetables and Fruits:
1 cup of salad greens = a baseball
1 baked potato = a fist
1 medium fruit = a baseball
1/2 cup cut fresh fruit = 1/2 baseball
1/4 cup of raisins = a large egg
Grain Products:
1 cup of cereal flakes = 1 fist
1 pancake = compact disc
1/2 cup cooked rice, pasta, or potato = 1/2 baseball
1 piece of cornbread = a bar of soap
Dairy and Cheese:
1 1/2 oz. cheese = 4 stacked dice or 2 cheese slices (Yes, my drawing only shows 3 Dice!)
1/2 cup ice cream = 1/2 baseball
Meat and Alternatives:
3 oz. meat, fish, or poultry = a deck of cards
3 oz. grilled/baked fish = a checkbook
2 Tbsp. of Peanut Butter = a ping pong ball
Fats:
1 tsp. margarine or spreads = 1 die (referring to dice)

If you have been making progress with respect to eating a healthier diet then getting a handle on portion size may be your next step to successful weight loss and maintenance. Good luck!
In my next post I will share the menu for day 2 of the 7 Day Diet Plan for weight loss with a healthy 1200 calorie diet including how you can modify the plan for a 1300, 1400, or 1500 calorie diet. Till then watch those calories, portion sizes, and eat healthy food!
